Title: HD-AVA (and HD-AVP) issues. Defective unit or plain limitations?
Post by: simondadiamond on 25 Sep 2016, 10:56 pm
Hey, sorry for the long post but I have been having issues with my HD-AVA and I am wondering if I have a defective unit, or are these just limitations of the device?


1) No USB DAC input button on the remote control... isn't this kind of one of the main selling points of the device? the amazing DAC? with a slew of buttons, one for the USB DAC should really be there, am I just blind? I have to go through a list of like 20 different inputs to change from USB DAC to HDMI DAC (Which I will be doing a lot)... Also, there seems to be "A,B,C,D" buttons but the manual says they are reserved, I can't seem to save any settings on them. Having these work as button setting presets would "fix" the issue of not having a dedicated USB DAC button!!!

2) USB DAC drivers (or internal wiring) have switched the left and right channel... This would not be a big issue if I was not using both DACS

2.1) When using the USB DAC, the NuPrime seems to detect it (when I click on the info button) as Analog 8ch 48KHz, though the USB driver seems to detect it correctly, 8ch analog doesn't sound right at all so I will trust that it is a bug and I should trust the tiny GUI for the driver.

3) The AutoRoom correction does not seem to detect  my left speaker (tried with different cables, and different speakers, it just skips it and configures the right speaker and the subwoofer.
John Casler reported in another post of mine that this is not normal

4) The EQ and bass management do not seem to have an effect on the USB DAC.
Confirmed normal by Jason from Nuprime

This is a real shame, mostly due to the lack of bass management... it actually sends what I believe to be full range signal to the subwoofer ( I tested all variables with only the subwoofer connected) When using the USB DAC, the subs sounds like a cheap boombox lol, I can hear high frequencies and all!!!  And I can't seem to find a way to put a cutoff frequency as I can with the HDMI multichannel DAC or turn the subwoofer off for that matter, only attenuate it by 10db . The only way would be  to go behind my unit and unplug the subwoofer to avoid this if using the USB DAC. Surely I am missing something?

5) The HDMI handshake does not seem to take place properly, every time I turn my NuPrime on I have to go into the settings on my computer, disable the TV monitor, then re-enable it or I have no audio or video. This could be windows 10/my computer though... not NECESSARILY the NuPrime.

6) I am really not sure if the different sound modes are working properly, as half of them I can't select ( Dolby Pro Logic IIz, DTS Neo:6 which appear on the on screen display but cannot be turned red as pure audio and pure direct).This is probably due to the fact that I only have 2 speakers connected though, so I will see with a 3rd center channel (amp on it's way

You have similar problems with your HD-AVA as I have with a HD-AVP which is a similar device

Yes, the USB does swap the channels around
You cannot select the USB input directly from the remote, you must press Input and scroll down, or turn the left hand knob slowly
The HDMI handshake affects all inputs.  I use USB 80% of the time, yet if I switch on the TV, the sound disappears for about 3 seconds
I noticed that the amp sends the full range to the subwoofer.  However, I was able to configure the sub to ignore everything above 120Hz

In addition I find

The display on the front panel goes out in HDMI mode if another setting other than "Direct" is chosen
I cannot access the GUI menus and can only get them to display by selecting USB and then turning on a TV.  The HOME button does nothing
There is always sound from the rear speakers unless "Direct" is selected.  Jason contradicted me on this, but it is easily discernable
I cannot play SACD discs.  The SACD player states that there is no DSD compliant device attached

However, I discovered someone who lives a hour away who has a HD-AVP.  His GUI menus all work, he can connect to his wifi network.  His display stays on in all modes.  I was unable to check the other perceived shortcomings

Also, NuPrime take 2 months to reply to messages.  I don't want to get to the stage where the warranty has expired and they wash their hands

Having mentioned all this, I am pleased with th USB sound, it is by far the best I have heard

Hey,

Thanks for the input! I am in contact with Jason himself from NuPrime and my dealer is checking in with his sources as well as for me the flipping of the channels and the "fullrange" SUB ( ok if I upgraded my subwoofer to one that had controls on it I could avoid this but I am at the moment not in a position to waste even more money as all my savings went into this unit!!!) are borderline dealbreakers for me...

I seem to be able to use DSD content bitstreamed from JRiver. It's still a new app for me so there may be some conversion going on (especially since its hard to tell as the GUI displays 8ch analog when in USB DAC mode.... lol should be like 2 channel 1bit or something like that for DSD)

Really sorry and I am embarrassed by this situation. You are an international customer so initially the inquiry did not get to our support. But later even if it did get to us, it still took us way too long to get back to you. I have beat up on our support guy several times on this issue. His excuse was that he has been waiting to get the outside engineer who did the AV decoding to response.

Oh no, your warranty will not be expired and if there is any defect, you have my word that the date you report it is the effective date.
We also don't pay close attention to warranty expiration date. If it is a problem, we will take responsibility.
For example, if your product just happens to fail one month after warranty expiration (or two months...), we will still fix it free of charge.

I want NuPrime to have a culture of treating customer right (we have many customers that come back for many years since NuForce). And we don't hide problem.  If we screw up, like this case, we admit to it. 

We have been relying on international distributors to handle their customers problem, but we need to do a better job of a) supporting them and b) allow international customers to reach us more effectively.  USA customers have a help desk system for reporting.
So I am going to setup a separate help desk system for international customers and dealers.

Ok, thank you.  I will be a bit more patient

A few years back I had a BMW (a fairly upmarket model) but the local agent was atrocious, losing the cover plate when changing the oil, leaving off the brake fluid reservoir cap, and snotty to boot.  It developed an oil leak within the 3 year warranty and they had 5 goes at trying to fix it, continually telling me that this was not a guarantee fault and attempting to recover the workshop fees.  The last time I took it in 10 days prior to the expiry of the warranty.  They told me they were awaiting some part and kept the car, and the day after the warranty expired, quoted an astronomical amount to fix what they had 5 goes at fixing before.  My local garage fixed a rubber plug which had been inserted back to front, in 10 mins and did it for free.  So I have been bitten by a supposed upmarket car dealer and are not familiar with NuPrime and their ethicacy, but at least you do receive some feedback on this forum

I think the 8ch display is just window-dressing.  I looked at another HD-AVP which does not do some of the strange things that mine does, and his is the same in this respect

I have an issue with trying to read files from a USB thump drive, or portable USB drive.  How do I select it?

The manual says I need to plug in the USB drive, then select File Manager to access the drive.  It doesn't work.  All I get in File Manager is two options:  Network, and uPNP.  My drives are not showing up.  They are formatted FAT32 as that's the format that usually works with other similar devices.. but the manual doesn't mention anything about formatting the USB drives.

Help?

It did not work on my HD-AVP either, yet worked on another HD-AVP I looked at.  The "Media" button on the remote displayed USB Cruzer on the screen and when Enter was pressed, showed the music files on the drive

Please send this "USB drive problem" to support@nuprimeaudio.com.
For your AVP, please also try another USB drive to see if it makes any different. I am only speculating that it could be some USB drives are  borderline connecting with AVP such that it can be seen by one AVP but not another. So it might not be the problem with AVP but the USB thumb drive. It is hard to say.
Anyway, please contact our support staff to check it out.

I fired up the AVP today, but this time, I plugged in the USB thumb drive before turning on the AVP, hopefully making the AVP see the USB when it booted.

And it worked.  I was able to plug unplug both thumb drives that weren't working yesterday, one formatted FAT32, the other Mac OS Extended (Journaled).  I was able to navigate and play files on both thumb drives.
Unfortunately, no amount of plugging / unplugging made my portable 2.5" hard drive seen by the AVP.   I even tried a powered hub to give the HD more juice, but no go.

I have no problem with the portable drive (Western Digital) connecting to HD-AVP.  Try another portable drive if you have one (I have 4 or 5 lying around over the years)

I used 3 different Western Digital Passport 1T drives at the SHOW and they all worded fine as did the USB sticks.

I wonder what "size" drives U R using and if that might factor in.  I don't know the size limit.  :scratch:

I guess I am confused here.  As Jason knows I am a Nuprime fan and own an IDA-8 and both of the "10" pieces.  If you got or get a unit that doesn't operate as advertised or per the instructions in the manual send it back for a replacement or if the dealer balks a refund.  The amount of time you guys are spending trying to make "quirky" units work is time out of your life.  You paid for a fully functioning unit so get one. If not file a claim with PayPal or your CC company.  It's really that simple.  If your unit doesn't work out of the box you don't need to contact "support" send it back.

Post by: triumph on 11 Oct 2016, 03:06 am
Quirky is right... functionalities keep adding up the longer I get the unit!

Today, 2 of my drives worked out right away.  Both the Seagate and the WD (320G, I keyed in the wrong size earlier) are working fine.  But the Toshiba and a Fujitsu (found that one in a drawer) do not.

It's like the AVP software is slowly learning about me... scary!  Skynet, anyone?

Unlike stereo products which are very straight forward, AVP, WR-100, and other later products that involve complex features with software app, OS, firmware are sometimes not so easy to determine whether it is a bug or not.
In any case, a guiding principle is "Customer Satisfaction".
Title: Re: HD-AVA (and HD-AVP) issues. Defective unit or plain limitations?
Post by: JackD on 11 Oct 2016, 05:19 am
Thank you Jason as I guess that was my point.  If the product doesn't work due to software or even hardware issues let the factory figure it out and not the buyer in the field especially if you live outside the US.  If the dealer or even worse the distributor balks outside the US then let the financial parties fight it out while you sit on the sidelines. I had a faulty IDA-8 from the first batch and I just got a new flawless one in less than a week. I let the support staff figure out what was wrong with the first unit.  Not my problem to deal with.  So to all of you guys that are getting a unit that has issues just send it back.  Quit looking for answers on the forum.  If out of the box it doesn't work as the manual says it should send it back. But that doesn't apply to those who hook stuff up without reading the manual first.  Something I learned a long time ago when buying used or new.  Read the manual before the product shows up at your door and then you won't have problems or surprises.
Title: Re: HD-AVA (and HD-AVP) issues. Defective unit or plain limitations?
Post by: triumph on 11 Oct 2016, 06:11 am
Thanks Jason.  Yes, stereo is much easier!  :) 

Jack, I did read the manual... but since you don't have the AVP, I guess you didn't read it... it is quite... succinct... to be honest.  Most functions are not covered by the manual, so I guess posting here will let others understand how the AVP works, without getting customer service swamped with the same questions over and over with no time to devote on other things. 

I hope my USB DAC problem is a software problem and not hardware.

So, on to testing…

I had a separation problem with the iMac that is connected to the AVP. 
I made an audio file to steer the sound hard right and hard left.  When I played on the iMac, both channels were still playing, with a slight 5 or 6dB less in the channel that was supposed to be quiet.

I took my Mac Mini down and hooked it up.  Now, I get good separation R and L.  So, my iMac has an audio driver problem…

Switching to the mini helped finding how things are wired in either software or hardware.  That’s for NuPrime’s engineer to find out, I guess…  :)

With the Mini, I find that the right surround channel is playing the right front channel, and the left surround channel is playing the right front channel.

With the centre channel, it is playing the right front channel only.  When sound is panned to the left, there is no sound from the centre channel.

Now, to find if this is related to Apple’s own audio drivers, I will hook a Windows box tomorrow, I just ran out of time today.

Will keep you posted.

Didn't indicate whether or not I thought you did or didn't read the manually but you would be shocked at the number of owners who jump on forums and ask questions and complain while the manual is still in the plastic.  Your problem is obviously bigger than that as it appears are the problems of the others with these two pieces.

I initially had insufficient volume issues using USB until I configured Audirvana to "control" the HD-AVP.

I still have output on the rear channels playing stereo on USB, the GUI on the screen does not operate.   The agent said he would test one but I have not heard from him.  MyDtss takes 2 months to respond to questions and then answers half of them

I have had a 34 year career  installing, setting up and repairing electronic equipment, mainly access control, home theatre, satellite tv, pa systems and have seldom seen a product which has a poor manual and differs so much from what it is supposed to do as this device

Look the USB works well no doubt, the HDMI inputs are (mostly) fine, but all I expected was a device that worked as advertised and not a portion of it.  Telling me that I have got a bargain and I should have paid much more for this product does not wash with me.  In this country the HD-AVP is not particularly cheap

To follow up on my post #18...

I got a Windows 10 box running and tested the hard panned right and left audio file on Windows with the NuPrime Asio driver (BTW, it is located under the uDSD support download folder, but not under the AVP/AVA support folder... Jason, you might want to add the driver inside the AVP folder as well).

Same thing as with the Mini.  Centre channels output from the right channel only, and rear channels are linked to their respective front channels.

Tested the same file on the 7.1 DAC, and there is no channel bleeding happening.  All is fine with the separation with the 7.1 DAC.

Hopefully, this can help NuPrime engineers pin point the problem with the USB DAC.

The AVP is in a class on its own.  There is nothing on the market with a multichannel DAC, and at this price point.

If we can sort out the USB DAC, which sounds great, then it would be quite the unit.

And if NuPrime wants to hit a homerun, I would suggest these:

- Make the USB button on the remote shuffle between the InPlayer and the USB DAC.  Right now, that button only choose InPlayer.  Should be easy to do with a firmware update.

- Have the USB DAC access the crossover and EQ already there for the 7.1 DAC.

- Although it would probably mean a new unit design with an extra port, if it were possible to have access to the 7.1 DAC via USB as well.  Then, I'm sure NP would sell containers of AVP!  There is nothing on the market right now between the very cheap sounding multichannel U-DAC8 offered by miniDSP, to the much more expensive e28 DAC by Exasound.  NP would have the middle ground all to itself.

- or, ... could the USB DAC be used for Mains R/L all the time, and the multichannel DAC for the other channels only?  Get the best sound for stereo playing and still have access to multichannel DAC.  Although, there must be a reason why it wasn't implemented like that in the first place...

My 2 cents....

A frequently asked question about USB audio as the source is what happened to the outputs?
The USB RCA outputs will have fixed 2V max output (i.e. none volume controlled) from the "DAC-10 equivalent" USB DAC board.
The 7.1 outputs have the following behaviour:
1. If the mode set to Pure Audio, then the main L+R have the volume controlled USB DAC output.
2. If the mode is set to any other, then all 7.1 channels will have outputs.

Mode selection is not available when using the USB DAC. 

There's no way to access Pure Direct, Pure Audio, etc....
Title: Re: HD-AVA (and HD-AVP) issues. Defective unit or plain limitations?
Post by: chrisc on 13 Oct 2016, 06:02 pm
There appears no difference in sound, I agree.  The only alteration I can see is that in Pure Direct mode, the front panel stays on, whereas in other modes, it switches off after 6 seconds  (this is on USB in)

Wait,... are you saying that Mode selection (Pure Direct, Pure Audio, etc..) is available with the USB DAC?

That makes no sense, since the USB DAC doesn't have access to EQ, and such.

If I have a thumb drive, or any other analog or digital inputs, I have access to Mode Selection, either on the remote or the OSD.

But, with the USB DAC selected, Mode Selection with the OSD just jumps from Input to Parameters, and skips Mode.  Same with using the remote while on USB DAC, Mode do not change.  And that was my understanding of the USB DAC, where EQ and playback is controlled by the computer.

Is it not?

Title: Re: HD-AVA (and HD-AVP) issues. Defective unit or plain limitations?
Post by: rustydoglim on 14 Oct 2016, 07:03 pm
Let me confirm. But I think the Mode should be set to Pure Audio before choosing the USB Audio as source.
Title: Re: HD-AVA (and HD-AVP) issues. Defective unit or plain limitations?
Post by: chrisc on 15 Oct 2016, 03:34 pm
Whether or not you choose Pure Audio before or after selecting USB makes no difference.  There is no audible difference either way, and injecting a 1KHz tone into the USB input gives the same output voltage whatever mode is chosen.  All that happens is the display on the front panel alters.  But this is just the display, controlled by another part of the processor.

If you are using HDMI-1 or InPlayer, the front panel display goes out after 4 seconds.  If you then press Pure Audio, the display comes back.  This shows that a part of the command has been accepted by the display logic controller, more than likely a command, "if input Pure Audio, then high display voltage assign" and "if input < Pure Audio, set low display voltage assign".  I have programmed PLCs to do this, to switch on lights upon the threshold of voltage from a daylight sensor falling below a selected level

Likewise at a Wine Farm, you would want the stirrer motor to come on should the temperature at the base of the tank fall below say 6 deg C to enhance firmentation.

However, if you do not check your settings, you can have all sorts of problems arising.  This is what I think happened with the HD-AVP, it was rushed to market without being tested.  Not nearly as bad as Samsung's Note 7, but you get the idea.  I am sure that with the application of some thought and time, many of these anomolies can be sorted.

Well, its 6 weeks since I last commented on the HD-AVP and several more about some deficiencies that the one delivered to me has (cannot use or program GUI menus).  The local supplier promised to exchange this for another and told me twice that he would be sending it to me within a day or two

I'm sorry to say he has not sent anything and does also not respond to emails.  He has a business partner in the city where I live so I complained to him about this.  His attitude was that this other fellow would send another unit when he was good and ready

I have also sent 3 queries to NuPrime's help desk.  I received one reply that I should read the FAQ on the website, nothing more.  No suggestions about how to resolve the problems

You might expect this poor showing from a dodgy used car dealer, but I get the impression that my complaints are a nuisance, and if ignored, will go away.  I operated a successful electronics service business from 1976 to 2012 and can assure you that this is not the way to keep customers

I bought the AVA a few weeks ago and it seemed to work fine. Last weekend I tried USB audio and got issues..
When using USB, the left and right channels are switched and the rear channels are playing also as some others here have reported.

Is there a fix for this or should I just send the product back? I bought it for the USB functionality and my plan is to use it with a PC running dirac room correction so the channel swapping is unacceptable.

If you are using the USB DAC through the USB DAC RCA Mains exclusively, then it should be fine.  It's the multichannel DAC Mains that are swapped when they playback from the USB DAC.

If you need the multichannel DAC Mains, while using the USB DAC, just swap the R/L channels RCA connectors.

About the outputs to the rear channels, I hope you can choose a mode in your multichannel amp that outputs only 2 channels, or turn off the surrounds and centre channels' amps.

I have received a (new) replacement HD-AVP from the agent and it works as expected, thank you.  Shortly, I will compile a list of "tweaks" that owners may apply to their units to overcome apparent faults and anomolies

To answer the last post, if you choose "Pure Direct" either on the remote or on the front panel, you will only get a stereo signal from a USB source, nothing from the rear channels

One upgrade or update that would be welcome, if it is possible, is to have DSD support on HDMI audio.  This will enable a SACD player that uses HDMI output to play the SACD layer on discs.

Does the facilitator know if this is being considered?  Also, what updates are in the pipeline.  I am sure readers would like to know

For the auto room setup, did you use the original high quality microphone that came with HD-AVP? You should email support@nuprimeaudio.com.

Yes the original microphone was used to no avail!... I have been waiting 4 months on  support for this.
 
The nonresponsive left speaker if software related would really need to be fixed!!!

Also the switching of the left and right channel is completely unacceptable. This must be able to be fixed via firmware somehow??? This should be a top priority!!!

I fixed this by turning a connector on the usb dac board 180 degrees and it helped. Got instructions from my dealer.

No luck on the rear channel playing from usb source though.
chrisc: was the solution on this to have a replacement unit or was it solved by some setting that I miss?

So, to get this straight, you opened the HD-AVA/AVP, disconnected the connector going to the RCA outputs of the USB DAC, flipped it, and re-connected it?

If that's so, I'll have to do that!

The replacement unit behaves exactly the same as the first one I received.  However, I was able to ascertain exactly what the various faults (minor ones and major ones) were and convey them to the local agent.  However, he was not interested

In the meantime, as you know, the retail price was reduced by 55% so people who purchased prior to November now have a unit with much less intrinsic value.

I will in due course post what has been occurring with my HD-AVP since December 2016

I was warned not in any circumstances to open the unit, or the guarantee is invalid
