            Bug ID: 37955
           Summary: USB DAC sound problems
           Product: Wine
           Version: 1.7.35
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

Hello,
I use the Fiio e10 external USB dac as a "sound card".
My PulseAudio-enabled Archlinux box works mostly very well with it. I did the
following to get it working:
1. Set up correct sampling frequency (96000) in the PulseAudio setup. However,
some programs (especially games) were still making trouble.
2. Set up correct sampling frequency for OpenAL in /etc/alsoft.conf. This has
solved all problems I had - except Wine, unfortunatelly. 
3. Sound in Wine doesn't work very well. It is hard to describe, but it is
really messed up. Games don't work and the sound test in winecfg doesn't work
either.
I am searching for a way of how to try and fix at least the sampling rate (I
ASSUME that it might be the root cause), but neither winecfg nor regedit allow
to specify it.
I keep getting this error:

ALSA lib pcm.c:7843:(snd_pcm_recover) underrun occurred

Do you have any idea of what to do?
If I use the built-in sound card, sound works well, but that's not the solution
I like.
