After some more reading and experimentation I was able to build aplay/arecord and they're working.  I also built PortAudio for unix/OSS and it seems to work as well with ALSA's OSS emulation.  Still not sure why I couldn't cat a file to /dev/dsp which has worked for me in the past...

Have you tried madplay? It worked for me through ALSA and A2DP Bluetooth.

Using the current oe (as of tuesday) to build  basic image for a

When I cat a wave file to /dev/dsp, snd-soc-gumstix gives me noise and  
snd-pxa2xx-ac97 gives me silence.

No errors during boot, and the alsa device seems fine based on /proc/ 

reading or writing to /dev/dsp seems to change the sample rate to 8K.

Are other people having success with audio lately?
