I have a problem that may be related to yours. When I play any video with mplayer and I use / or * to change the volume I get this error message: [AO_ALSA] Unable to find simple control 'PCM',0. But I do have sound, which I can turn up or down with the gnome volume control. All this, with pulseaudio running. If pulseaudio is not running, I don't get any sound at all from mplayer. Haven't tried other programs. Also echo "Hello world" | flite flite: pcm_params.c:2351: sndrv_pcm_hw_params: Assertion `err >= 0' failed. Aborted Probably related to above.
