I would think that this sounds like a version mismatch. How do i come to this result? Well, alsamodules seem to be laoded fine [as you have checked /proc/asound/cards]. Oss emu is working too [as you /dev/dsp test shows]. The OSS emu [modules] don't interact with alsa-lib. But the pcm-test program uses alsa-lib.. which version of alsa-drivers do you use [cat /proc/asound/version]? which verison of alsa-utils do you use [aplay --version] which version of alsa-lib do you use? [$EDITOR /usr/include/alsa/version.h]? Flo P.S.: oh i just see you use ARM. I have no idea, if that platform has specific issues, so this post could be void afterall.. -- kT ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
