The ALC650 (which is what you meant, right?) is indeed not recognized by ALSA's AC97 code, if I understood that part of the sources of 0.9.0rc1 correctly. That can be relatively easily fixed by adding: { 0x414C4720, 0xfffffff0, "ALC650", NULL }, to snd_ac97_codec_ids[] in ac97_codec.c With that little change the ALC650 is apparently detected alright. Only, it doesn't work any better. =) If I try to use the via8233 module, I get the same result as you when playing (no sound, I/O error). But even with the ALC650 added to ac97_codec.c, modprobing snd-intel8x0 doesn't work: root@byblos:~# modprobe snd-intel8x0 /lib/modules/2.4.18/kernel/sound/pci/snd-intel8x0.o: init_module: No such device And the syslog reports that the ICH device wasn't found or is busy. So I guess it's not just a problem of AC97 not recognizing the ALC650. Argh. I'l keep you informed, should I somehow manage to get it to work (unlikely, but eh). :) -- S. _______________________________________________________________ Have big pipes?
