Explore a little bit files content under /proc/asound Such as: /proc/asound/cards /proc/asound/devices /proc/asound/pcm /proc/asound/card0/codec* Fallback to simple stuff such as speaker-test -c2 aplay somewavfile.wav aplay -l aplay -L I have found it useful and very interesting to do strace -e trace=open speaker-test -c2 That shows you all config files that alsa-lib opens. ________________________________ CONFIDENTIALITY : This e-mail and any attachments are confidential and may be privileged.
