I'm using J.River Jukebox with ASIO and Win XP, works great.  I trialed J.River Media Center and I couldn't tell a difference.

I have found this ASIO driver www.usb-audio.com to be superior to ASIO4All.

According to J.River, ASIO support is one (of many) reasons to upgrade to Media Center from Jukebox.

The "media jukebox" homepage also says that it supports Asio playback
I wonder what the difference is...

[srb]

Hmmmm.....
 
Mijknarf, does the ASIO driver show up under Tools > Options > Audio > Audio Output > Output Mode?

I know in my case it doesn't support WASAPI, so I guess for me it's a non-issue, but I'm curious.

Mine shows up under output mode because I have not updated my Jukebox software to the most recent version.  Apparently it's no longer included in the Jukebox version???

[Mijknarf]

SRB,

I'm running version 12.  The most recent is version 14.  Not sure when ASIO was taken out?

[rtate]

So If Asio was taken out  of the newer versions, can I manually reinstall it or
is it not supported at all ?

rtate- when I downloaded Media Center 15 last week I'm pretty sure ASIO was there with it because it showed up in the drop down list I was using to setup the audio interface. Its possible that the program saw like someone mentioned another install of ASIO that was already on my PC but we're talking from years ago.
 In either case I went and found the latest and greatest ASIO for all and installed it to make sure I had I good install and it worked fine. I don't remember exactly where I got it from, I think I just Googled it and followed the links shown, so yep you'd be ok.

Hi all.  I'm a developer at J. River.

You can read more about J. River Media Center audio output modes here:
http://wiki.jriver.com/index.php/Audio_Output_Modes

WASAPI, WASAPI - Event Style, ASIO, Kernel Streaming, Direct Sound, Wave Out, and Disk Writer are all supported natively with Media Center.  Media Jukebox only has Directsound, Waveout, and Disk Writer.

As you can read at the link, we recommend ASIO, then WASAPI - Event Style, then WASAPI, then Kernel Streaming in that order. 

There's no reason to use ASIO4All as it's simply a wrapper around Kernel Streaming (and we natively support Kernel Streaming, so you can just use it directly).

Thanks.

It does appear that they have removed ASIO and WASAPI support from MediaJukebox.  I have JRMC 15 installed on this laptop and it sees the ASIO driver for my USB Mobile-Pre device just fine. Out of curiosity I downloaded MediaJukebox 14 and installed it and it does not list ASIO or WASAPI as an output choice.

J Rive jukebox is Media Center 14.
If you want to know the differences simply search http://yabb.jriver.com/interact/index.php?board=19.0 on “Available here”
This gives you an overview of all what has been added to 15/16

WASAPI is not installed by JRMC
It is simple part of Win from Vista on.

ASIO only works if you have a sound card supporting it (license)

ASIO4ALL is kernel streaming, often it don’t work on modern mobos running Win7

[rtate]

So I installed Media Jukebox and would like to optimize the settings for the best quality
playback.
Should/Can I install asio4all if so ,how do I go about getting it to work.Right now I have
Asio4all saved on my desltop.
If not how do I go "hardware direct"   

[eclein]

monkey-Thanks for that info, very good source to use and if I understood it a caveman can understand it. I tried" WASAPI-event" but it did not work out so I'm using WASAPI, I never had good success with ASIO myself, that doesn't mean everybody else can't use it successfully so don't not try it.....

MediaJukebox no longer supports ASIO so ASIO4ALL is useless for this program.

I have MC16 and initially all I could use was kernel streaming. Unticking the the "play from memory" in output settings solved this problem giving me access to WASAPI and WASAPI Event Style but I still can't use ASIO. A previous post talked about not being able to use ASIO unless I had a sound card that supported it and therefore a licence. Surely the idea of direct streaming is to bypass the crappy soundcards that come with all PCs. I use a uDAC2 via my USB output as my DAC and I have disabled the soundcard in my BIOS. So what do I do now if I want ASIO and is it really that much different to either WASAPI or kernel streaming?

WASAPI, ASIO and Kernel Streaming bypass the internal Windows Mixer to give bit-perfect output and avoid internal resampling, and also allow the sound device to have exclusive control, if enabled.  They do not bypass the soundcard.  In your case, the uDAC2 USB DAC is your soundcard, and as such, it needs to support ASIO - which it presumably does.
 
It looks like others have used ASIO with the uDAC2 so I don't know what your particular problem might be, but since you apparently have Windows Vista/7, the WASAPI driver is designed to take advantage of the new audio stack within those operating systems, and is the driver of choice for myself and many others.
 
J. River recommends choosing the sound driver in this order:
 
1) If your hardware has a native, well-behaved, ASIO driver, use ASIO
2) Otherwise, on Windows Vista, Windows 7, or newer, use WASAPI exclusive
3) Otherwise, use Kernel Streaming if it works
 
The order of recommendation is not for sound quality (they all bypass the Windows mixer), but for guaranteed compatibility and stable operation.  So perhaps your ASIO driver is not so "well-behaved"? 
 
In any case, I would choose WASAPI.  I do have "Play files from memory instead of disk" enabled and I am able to choose any of the sound drivers.  If not already enabled, you might want to try enabling "Open device for exclusive access" under Audio Output > Output Mode Settings and see if that will allow you to also enable memory play.

G'day Steve

Thanks for the reply and adding to my pool of knowledge. When I went to WASAPI event style mode I found the uDAC2 already had the box ticked for exclusive use. I reticked play from memory and this is all OK. However, ASIO still won't work and maybe I have to adjust the settings but ASIO doesn't recognise my uDAC2. This is not an issue as the sound I'm getting from the other outputs is superb.

My Fiio E7 just landed in the country today and I already have an E9 to hook it up to. Let's see if ASIO recognises the E7?

Hello Steve

I started another thread in the DC that might have been better posted here.

Here's what it says and I'd be interested in your feedback

I finally got ASIO to work in JRiver MC16 by installing the ASIO4ALL plug in and now this little green arrow comes up in hidden icons section of the task bar. It may be my imagination but ASIO sounds better than kernel streaming or WASAPI. Clicking on the green icon brings up a window that gives me some configuration options for ASIO and I'd like to know what to change or leave.

 At the moment default appears to be:

 Latency compensation 32 samples IN and 32 samples OUT

 Hardware buffer (when ticked) gives a buffer offset of 10ms but nonticked which is default has kernel buffers 2. I can slide this up to 4

 Always resample 44.1<->48khz is ticked.   Is resampling a good idea?

 Force WDM to 16 bit is not ticked  - does this mean I am already running in 16 bit mode?

 Finally ASIO buffer size is 512 samples

 I am using the E7/E9 as a DAC amp

 So do I change anything or leave all as it is? BTW, ASIO was the top choice from the JRiver website as the preferred method of direct digital streaming and based on my ears I can understand why.
