Just wanted to help out with testing stuff.

I compiled your snapshot on my gentoo Linux x86_64

Compilation, installation and loading the drivers went smooth.

And, yes, there is sound...

Here some infos:

So now the funny part:

I was testing a few samplerates:
Used a 1 kHz sine, 0 dBFS, 16 bit mono wave file, 96 kHz sample rate
and rsampled it with sox:
for i in 88200 50400 50000 48000 47250 44100 44056 32000 22050 11025 8000 ; do
sox 0_16_96000.wav -r ${i} 0_16_${i}.wav ; done

and played them with aplay:

for i in 96000 88200 50400 50000 48000 47250 44100 44056 32000 22050
11025 8000 ; do echo "Now playing 0_16_${i}.wav" ; aplay 0_16_${i}.wav
; echo "DONE" ; done


96000 --> O.K.
88200 --> No Sound
50400 --> No Sound
50000 --> No Sound
48000 --> O.K.
47250 --> No Sound
44100 --> No Sound
44056 --> No Sound
32000 --> No Sound

22050 --> SYSTEM FREEZ
Playing WAVE '0_16_22050.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono

11025 --> SYSTEM FREEZ
Playing WAVE '0_16_11025.wav' : Signed 16 bit Little Endian, Rate
11025 Hz, Mono

8000 --> No Sound

Let me know if I can help out testing some more stuff

kind regards
