Looks like the stream setup doesn't match with your device. > I'm using alsa-lib-1.0.14-0.4.rc3.fc7 The more important thing is the version of ALSA driver you're using. Try the latest ALSA version (not released one), HG version, at first. If you don't want / have HG, try the daily snapshot tarball below: ftp://ftp.suse.com/pub/projects/alsa/snapshot/ Then check whether it's a supported device or not. If yours is an unsupported one, you'll see a kernel messages like "unknown model, using BIOS..." Anyway, you can try different model option value for snd-hda-intel module, as listed in Documentation/ALSA-Configuration.txt.
