This should be a very last thing after confirming that you have really AC97 codec chip on your machine. > ------- > > snd-opl3sa2 results in: > > FATAL: Error inserting snd_opl3sa2 > (/lib/modules/2.6.18-4-686/kernel/sound/isa/snd-opl3sa2.ko): No such device > > unless I add some options in /etc/modprobe.d/sound: > > alias snd-card-0 snd-opl3sa2 > alias sound-slot-0 snd-opl3sa2 > options snd-opl3sa2 fm_port=-1 midi_port=-1 port=0x370 wss_port=0x530 > isapnp=0 dma1=1 dma2=0 irq=5 > > (These options were chosen by running alsaconf -> legacy ISAPnP -> probe > opl3sa2) You have to give port option. > I have also tried > > options snd-opl3sa2 fm_port=-1 midi_port=-1 port=0x370 wss_port=0x530 > isapnp=0 sb_port=0x220 dma1=0 dma2=1 irq=5 0x370 isn't the only value that opl3sa chip accepts. > Which is closer to what I have set in the BIOS. > > With these options, the module loads, but I get the following dmesg output: > > pnp: Device 00:0c activated. > ALSA > /usr/src/alsa/alsa-driver-1.0.14rc4/isa/../alsa-kernel/isa/opl3sa2.c:637: > PnP manual resources are invalid, using auto config > ALSA > /usr/src/alsa/alsa-driver-1.0.14rc4/isa/../alsa-kernel/isa/opl3sa2.c:233: > opl3sa2: can't grab port 0x0 > pnp: Device 00:0c disabled. > snd-opl3sa2-pnpbios: probe of 00:0c failed with error -16 > > An attempt at aplay gives > > ALSA lib confmisc.c:769:(parse_card) cannot find card '' > ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_card_driver > returned error: No such device > ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings > ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_concat > returned error: No such device > ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name > ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_refer returned > error: No such device > ALSA lib conf.c:3982:(snd_config_expand) Evaluate error: No such device > ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default > aplay: main:545: audio open error: No such device > > -------------- > > snd-cs4232, snd-cs4231, snd-sb16, and snd-ad1848 all behave similary.

Check the corresponding directory of /sys/bus/pnp/*. Also, you should try ALSA 1.0.14 release instead of the drivers in your old kernel.
