Benchmark DAC2 on Linux


Recommended Posts

I am using Arch Linux with an Ayre QB-9DSD. The only issue I encountered was that if the Linux computer is restarted, the power to the DAC needs to be cycled for it to reconnect. I keep my NUC on all the time with mpd running. You may find things different with the Benchmark.

Thanks guys.

 

Axiom, what do you mean by cycled?

 

Oddly my benchmark worked straight away after I installed Linux and now, a day later it doesn't show up in the sound settings at all? I have no idea what to do. Any advice?

Hi,

I've been using Benchmark DAC2 for over 2 years on Linux. Tried various distro-s - all worked (Ubuntu, Debian, Fedora, Arch). I am running squeezelite player on it and most of the time squeezebox (aka Logitech Media Server) on it as well.

All it takes is for alsa to recognise it (and it did by default). However after fresh linux installation open command line prompt type alsamixer and un-mute DAC2 (if it says MM under the bar make it 00)... in addition squeezelite has a new switch where it can do that on start ... needs some fiddling.

 

My ONLY and Major gripe with DAC2 is that via USB whenever sampling frequency changes (i.e. 96khz song followed by 44.1 regular CD) then DAC needs more time then per specs to 'sync up' with new sample rate. That causes about 0.5 seconds (and on some tracks that is first syllable or drum or something) to get lost ... if you have playlist that mix songs from various albums with different sampling rates - it will get annoying.

The ONLY solution i have found is to ask squeezelite to make 0.6-0.7sec pause between songs of different sample rates and that makes 'gapless' playback system little bit less gapless and as my HD collection grows it annoys more and more.

 

I don't think Benchmark ever released any firmware upgrades that might address the issue ... anyone knows ?

 

Other then that - i love the sound ... and features of DAC2 !

 

Let me know if any other help needed !

Sorry... to cycle the power: unplug from AC outlet, plug in again. My DAC has no power switch, maybe the Benchmark does. I found this was the only way to reconnect the DAC, just unplugging the USB cable did not work.

Thanks so much. I am still having problems! My Nuforce DAC works totally fine (as it always does, on windows too) but the Benchmark remains buggy! I checked alsamixer and its on 00.

 

Its recognised in Linux and I select it in sound settings but it wont make a sound when trying to play anything. Oddly, the U light is on as is the 44 light but standard 16 light doesnt light up either. Any idea why? It does in windows as I am testing it now.

 

Thanks

hi, have you tried speaker-test command ... not having bits light go on means DAC is receiving no data via USB. if speaker-test works or google 'aplay' command if you want to test if WAV file can be played. if that works then something is 'off' with settings in whatever you use for player ... not sure how much this helps... ?

hi,

why dont you try 1st in command line window following command:

aplay -L

on my pc here is the output:

then you pick (assuming Benchmark DAC2 does show up) simple thing like 'default:CARD=B20' and type following:

speaker-test -D default:CARD=B20

 

and copy/paste output of what happens. it should play pink-noise @ 48000 khz and lights on DAC2 will show you that :)

hi

zenpmd
,

you can see that major difference on your output vs mine is that your DAC2 is in USB 1.0 mode:

[color=#333333]front:CARD=B10,DEV=0[/color]
[color=#333333]Benchmark DAC2 [/color]USB[color=#333333] Audio 1.0, [/color]USB[color=#333333] Audio[/color]
[color=#333333]Front speakers[/color]

on my PC you can see this:

[color=#333333]front:CARD=B20,DEV=0
[/color]Benchmark DAC2 USB Audio 2.0, USB Audio
[color=#333333]Front speakers[/color]

 

I never used USB 1.0 mode ... so - look at the manual so i don't mis-instruct you but it is as simple as pressing and holding USB button on remote for 5 seconds and it will switch to USB 2.0 mode ... you might not need even to reboot your PC after that but do that to make it simpler.

 

see then.

 

as for 'speaker-test' command ... once you got it in USB 2.0 mode just copy/paste command ... then see if it works :)

Thanks very much. Results here, now in USB 2.0!

Do you know how to disable Pulse Audio on your distro? Pulse is well known to cause all types of issues including controling sample speed output.
