So far I cannot get sound out using cat /bin/bash > dev/dsp2 aplay -D hw:2,0 -f cd some.wav both return with device does not exist or similar The same for recording. arecord -D hw:2,0 -f cd -d 10 /art/code/alsa/test.wav ALSA lib pcm_hw.c:797:(snd_pcm_hw_open) open /dev/snd/pcmC2D0c failed: No such file or directory arecord: main:447: audio open error: No such file or directory --- ls /dev/snd/ controlC0 controlC3 midiC0D0 pcmC0D1p pcmC1D0c controlC1 controlC4 pcmC0D0c pcmC0D2c pcmC1D0p controlC2 hwC0D0 pcmC0D0p pcmC0D2p timer --- Are the pcm devices created by the mixer code? If so then can you use the descriptor info to hardcode them in? On a side note I would really like to know how you use the descriptor info to write a driver. You asked me for the same thing when you were doing the cmipci driver. It would be a valuable additon to the developers documentation. Something like "Using the information provided in /proc/asound to write a driver". If you/Paul/Jaroslav/Abramo or anyone else who grok it could write up some quick notes I will gladly incorporate them into the online docs. I am going to write up some info now on the installing the usb-audio driver and add it to the wiki. -- Patrick Shirkey - Boost Hardware Ltd.
