According to his lspci, he doesn't have a second sound card. Any ideas? Besides that it seems that VolumeKnob is physically broken on STAC9205s, Can anybody here with STAC9205/STAC9204/STAC9254/STAC9255 test it? And last question, about STAC9254/STAC9255 There is no datasheet for that chip on the web, is this just STAC9205 + modem? Best regards, Maxim Levitsky
