No sound when playing DSF file through SOTM -sms100 and AUdio-GD DAC NFB-7

Themask · February 11, 2015

Hi everybody,

I need help to setup my systems based on SOTM-sms 100 feeding an Audio-GD NFB Dac by USB. The dac is with ESS Sabre 9018 DSD capable.

Playing PCM files is trouble free, but if I try a dsf file, I can see that the file is played but there is no sound!

I have tried with Logitech Media Server 7.9 with the DSD player plugin activated and the file type sate to native and dsdplay on LMS server side. On the SOTM side I have tried different values for the buffer and period count with squeeze lite activated without success :-(

I have also tried with minimserver combined with minimstreamer and the parameters dsf:dopwav and dff:dopwav, still no sound with dsf files.

What am I missing?

Thanks in advance

Serge

Serge,

Welcome to CA. Which NFB DAC is that? Where is Minimserver installed? What does Minimwatch's log show (if all DSF files show errors that is where we begin).

Themask · February 11, 2015

Hi Ted, it's the model NFB-7.

The minimserver is installed on my Synology NAS

Here is an extract of the minimwatch log set to verbose level:

Hope that can help.

Could you set to info mode and rerun...then make a text file of it and attach/post on the Minimserver forum too. Simon is excellent and getting back to you. I don't know what the log is saying but the words "transcoding" are not good. There should be no transcoding.

Dopes the rest of the verbose log show all the hundreds of files/directories it scanned?

Themask · February 11, 2015

Yes, exactly. hundred of lines about my directories. It is still scanning my folders. I will wait and try again when the scan is completed.Then I will post the log on Minimserver forum.

Thanks

Hi Serge,

Are you certain the NFB-7 supports DoP (DSD over PCM)? I believe the SOtM-sMS 100 plays DSD files via its USB ouput as DoP, so requires the connected DAC to support DoP. I've had a quick look at Audio-gd site and there doesn't seem to be any mention of DoP support. However, they do provide an ASIO driver for Windows, which could well be for native DSD support rather than DoP.

Hi,

Good point. I'm not sure about the answer so...sent an email to the constructor.

Meanwhile after few testing found that you can hear the sound but the volume level is very very low!Even to hear this, I have to almost set the volume knob on the preamp to the max and put ms ears very close to the speakers! Weird!

Any other idea?

Thanks

Serge

Cebolla · February 11, 2015

Yes, a very very low music volume can be a symptom of the DAC not supporting an inputted DoP signal. My Pioneer N-50 streamer, which has an internal PCM only DAC, does this if I get it to play DoP. It also masks the low volume with hiss/white noise.

The NFB-7 implementation of DoP is extrange, in my system DoP works with Audirvana but i get no sound with HQPlayer

Hi,

do you mean I will need a computer to play the dsd file with the Audio-GD NFB-7?

I have tried everything I can but still no sound. I'm little bit desperate. :-(

Serge

Cebolla · February 13, 2015

Which Audirvana version of DoP did you use: 'Initial dCS method' or 'DSD over PCM standard 1.0'? Also, what resolution of DSD files were you playing for both your Audirvana & HQPlayer tests (e.g single rate 64fs, double rate 128fs, etc)?

I believe double rate DSD wasn't defined until version 1.1 of DoP, so this might be the issue.

Cebolla · February 13, 2015

do you mean I will need a computer to play the dsd file with the Audio-GD NFB-7?

Unlikely, though finding out why DoP input to the NFB-7 works from one software player and not from another would most likely explain why it doesn't seem to be working from your SOtM-sMS 100 hardware player. If anything it shows more hope as the NFB-7 does appear to support DoP in some form.

Hi,

thanks for the reply. I don't use a computer to play the files. The SOTM is connected between a NAs (RJ45) and directly to the DAC NFB-7 by USB. There is no computer involved in the chain, and I don't want to use a computer/software.

Is this possible?

Thx

Serge

I think what Cebolla is suggesting is if you could use a computer as a temporary measure you can try a few configuration options that aren't possible with the SotM. With the computer you may be able to get to the route of the problem and either SotM or Audio-gd may be in a better informed position to help you.

I think the suggestion is that your NFB-7 may support only an earlier version of DoP (or perhaps a later version) which the SotM is not supporting.

ted_b · February 13, 2015

Guys, the SoTM server IS a computer. It supports DoP (all versions of DoP are supposedly backward compatible to 1.0), he has Minimserver hopefully set for DoP (he says he put dsf:dop, dff:dop in the stream.transcode block) and he is using some control point. I think the Minimserver log is our best weapon. What does it say about any of your DSF files? Not even a TXXX or TDAT warning?

I will scan just one specific DSD album and check the log. I have too many warnings in the log for other flac files.

It will be more relevant.

Will post the log.

Thanks

You have to transcode with minimstreamer. Add dsf:dop, dff:dop to the minimstreamer transcode properties box in minimserver.

This works on my sms-100.

Thanks but...please reread the thread. He said it here, in his first post:

and I reiterated that he has it covered here, today:

Indeed. Of course, it's also quite clear that the OP is using the SOtM to get away from using a traditional computer and its playback software.

Cebolla · February 13, 2015

Guys, the SoTM server IS a computer.

Well, yes of course it is - but why the association, when we we're clearly referencing a traditional computer running playback software? The SOtM is not being used as one of those as it's restricted to just doing its network audio playback/streaming duties, an important feature as far as the OP is concerned it seems.

It supports DoP (all versions of DoP are supposedly backward compatible to 1.0), he has Minimserver hopefully set for DoP (he says he put dsf:dop, dff:dop in the stream.transcode block) and he is using some control point. I think the Minimserver log is our best weapon.

The point of DoP compatibity was referring to the DAC itself, not the SOtM or more accurately MinimServer's transcoding function. If the DAC's implementation of DoP is at an older incompatible version, there's no way of MinimServer's transcoder automatically recognising that, even if it could make the adjustment through any supposed backwards compatibility.

It's certainly worth checking the DSD file integrity via MinimServer's log. However, DoP transcoding by MinimServer appears to have working during the DSD file playback by the SOtM, as the OP mentioned hearing the telltale sign of a very low sound of music playing, ie, it's likely the DAC was seeing the DoP signal as normal PCM, rather than being triggered by it into the mode for receiving DoP. Question is, why?

ted_b · February 13, 2015

Any time I've encountered a DoP incompatibility (especially the early days in late 2011 when marker/flags were inconsistent) the result is significant noise/hiss with a background of music. Is that what you are getting, Serge? You describe it as "no music" so I did not think of Dac DoP incompatibility, but as Cebolla points out, it is another one of the leading culprits here I guess. I assume you cannot borrow another DAC?

Any time I've encountered a DoP incompatibility (especially the early days in late 2011 when marker/flags were inconsistent) the result is significant noise/hiss with a background of music. Is that what you are getting, Serge? You describe it as "no music" so I did not think of Dac DoP incompatibility, but as Cebolla points out, it is another one of the leading culprits here I guess. I assume you cannot borrow another DAC?

Hi Ted,

Yes, "the result is significant noise/hiss with a background of music". I have to set the volume knob almost to the max to be able to hear the background "music". I don't have at the moment another DSD dac

I will try to find one...

Thanks

Serge

Serge,

The NFB-7 does seem to support DoP in some way, as indicated by Juliocat (using Audirvana). Unfortunately, Juliocat didn't mention the actual setting used in Audirvana nor the DSD file resolutions used, which may help in further investigations.

Obviously it's not working with your DSD files, Minimserver (or Logitech Media Server) providing the DoP via transcoding and pass through during playback by the SOtM sMS-100. Since you are getting a hiss/white noise and very low volume music, it indicates the NFB-7 is receiving the DoP signal, but not recognising it, so converts it to analogue as if it were normal PCM. I'm no MinimServer log expert, but the last one you posted does appear to confirm this, in that it is transcoding the DSD file you're playing to DoP without any issues.

Incidentally, you haven't yet mentioned what resolution of DSD files you are streaming.

Hopefully Audio-gd will get back to you on the NFB-7's DoP support, particularly if they can tell you the DoP version it supports and/or any restrictions on using it.

Hi,

My files are DSD64. (extract from iso to .dsf)

Thx

No sound when playing DSF file through SOTM -sms100 and AUdio-GD DAC NFB-7
