Touch and 96/24 files

mjock3 · « **on:** 6 Oct 2011, 11:14 pm »

I got a couple 96/24 files that I am trying to play through the digital out to a Bel Canto 2.0 DAC, but am unable to do so. Bel Canto tells me it can handle 96/24 but I get nothing. I can play the through the analog outputs but not digital. Anyone know of something that I may be doing wrong??

Thank you,

Mark

Do other files of less sampling play fine? Are there differences in the digital format of files of lesser sampling rates?

To my knowledge all files are flac. I did a file that I converted to 16/48 and it played just fine. All the other files play without a hitch.

Thanks,

Mark

Try taking the 24/96 file and "converting" it to 24/96. Sometimes that can fix a minor problem that prevents a file from playing in some setups.

Also, what is your software player, and how is the "output" defined in it's options? Some soundcards/drivers either won't play the file, or need settings changed in order to do so.

Tried taking the 24/96 and converting it to 24/96 uncompressed still won't play.

I am not sure how to answer your other questions, I am using a Dell laptop with the squeezebox server on it. Isn't that all I need? I thought since it plays through the analog outs on the Touch the data from the computer to the Touch is doing what it ought to. If not could you give me more info on what I would need to do to give you the info your are asking for?

Thanks,

Mark

I came across a topic on the Logitech forum where, like you, the user was unable to play 24/96 FLAC files through the digital output to his Burson HA160D DAC. He could play them into another DAC (actually a Yamaha receiver), but not into the Burson DAC.

Do you have another DAC or receiver with digital inputs that you could try to see if the Touch is in fact outputting 24/96 FLAC from the digital outputs, but for some reason is also running into a compatability problem with the Bel Canto DAC?

mjock3:
You were posting in the threads re:the Dynobot mod and IIRC you also installed the Sound Touch Toolbox 2.0 mods. Returning the Touch to factory settings is easy to do, just hold the power button down for a bit but you may also have altered the file settings on the SBS and those settings will remain altered even if you update the server version.

Steve:
I just saw your post and the Touch must have a software alteration for the USB port to fuction as an output. w/o that alteration w/ factory settings, the USB is an input only.

The user in that topic was initially using the USB port for an external hard drive connection, and then later confirmed he still had a problem trying to stream those 24/96 FLAC files from the computer's hard drive as well.

The only thing he mentioned about a USB output, was that the Touch did not have one and that he was using the S/PDIF output.

Steve:
I finally read the thread completely on your link and it does seem similar to this case.
However the op here, jock, has made changes (the TT2.0 mods) which may be causing his problem. Since the internal Touch DAC (the AKM 4420) can convert the files w/o problem and the Bel Canto works w/ 24/48 files, the issue is more probably the alterations.

Larry:
The Logitech forum user could play his 24/96 FLAC files using the internal Touch DAC as can Mark (mjock3). The modifications you mention might be responsible for this playback problem, but I thought I'd mention that there was a user that had a DAC compatability problem. It's likely that one of these is the culprit.

If a 24/96 capable receiver was handy, I thought that would be a quick test to eliminate (or verify) a DAC compatability problem.

Thanks Steve and Larry for your input on this.

I did a reset to factory defaults and it still will not play through the DAC.

Unfortunately I do not have another DAC to swap with the Bel.

According to the manual, apparently the Bel Canto DAC 2 can only play 24/96 DAD files.

DVD audio and it is very different from PCM or flac. The BC DAC2 is from 2002 or so when things like this weren't very common.

I guess I know now.

I was communicating with someone from Bel Canto and they were telling me it was a computer issue that I was not able to listen through the DAC. So I started trying to look into it.

Thanks all,

Mark

I guess it's time for Mark to upgrade to either 2.5 or there referance dac 3.5VB.

As a follow up. I contacted Bel Canto again about the DAD file and was told that it is nothing but a PCM file that is high rez. He believe's something that Chesky did. So for some reason my DAC 2.0 is not playing it. I did get my hands on another DAC and it plays the files fine.

Take a look at the how to rip hi-rez thread in the Hi-Rez circle. The DAD you have may be an MLP (Meridian Lossless Packed) disc vice a PCM disc. There are also HDADs (Alan Parsons) that have a 24/96 layer on one side and a 24/192 layer on the other.

DVDAExplorer and DVD Audio Extractor are the 2 programs. DVDAExplorer is used to rip the proprietary MLP layer off of DADs and HDADs. This is converted to WAV and can then be converted to whatever you want using DBPoweramp (FLAC, ALAC, etc.)

What disc is it that you are having problems with? It sounds like you're trying to feed MLP to the DAC vice WAV, etc.

The OP indicated they are files not discs - "To my knowledge all files are flac. I did a file that I converted to 16/48 and it played just fine. All the other files play without a hitch."

Phil got that, but if the MLP files were converted incorrectly that may be the issue. Just thinking...
