Trouble-shooting sound problems in FC2 needs a bit of background. The ALSA drivers support the native ALSA devices /dev/snd/* and OSS compatibility devices /dev/dsp, /dev/mixer and friends. Not all applications or utilities use native ALSA devices yet. E.g. system-config-soundcard plays the test sound via /dev/dsp (OSS). playwave uses SDL and ALSA library. ogg123 uses libao, which supports OSS and EsounD. If in XMMS you switch to OSS output, I assume you get the same static noise, right? And the same when you "cat" some WAV file into /dev/dsp. Some users seem to have problems with audio driver routing issues, where ALSA and ALSA OSS seem to be fully separate and one works while the other one doesn't. Setting the mixer levels with an OSS compatible mixer doesn't change the ALSA mixer levels for the same soundcard and things like that. You would use alsamixer for ALSA and e.g. aumix for OSS. > I think the right module is loaded when I checked using 'lsmod', but I can > give the complete output of lsmod if necessary (don't want to send > unnecessary big list right now). ALSA loads two sets of modules, one set for OSS (via modprobe.conf.dist), the other for native ALSA.
