The "pcm" mixer setting doesn't change the sound's volume at all, except at 0 where it mutes the sound as expected. The "vol" mixer setting has absolutely no control over sound, it doesn't change anything whether I set it to 0 or 100. If I set the "speaker" mixer setting to 0, it outputs a very loud beep. If I set it to 1, there is a small beep. If I set it higher, up to 49, the beep gets louder, and at 50 and above it doesn't output the beep anymore. I don't have a "ogain" channel. Interesting, isn't it? :-) As said in the topic, this is a SiS 7012 sound card. It has a CMI9761 ac97 codec (id == 0x434d4982 == "CMI" 0x82). It isn't in the list of supported codec ids on FreeBSD. It is however listed in ALSA's source code, and has chipset specific support code. I merged one of the workaround, which is for the specific revision of the CMI9761 chipset I have. Unfortunately, nothing changed. I wonder if anyone else is having problems with this chipset/ac97 codec, or if it's working fine for others. If someone more knowledgeable than me in AC97 code is interested to look at the problem, I'd be glad. I don't know enough about this to even know where exactly the problem may lie. Cheers, Maxime
