Thanks for your reply. I have now tried snd-nm256, snd-opl3sa2, snd-cs4232, snd-cs4231, snd-sb16, and snd-ad1848 with this hardware (Dell Inspiron 3500, Neomagic NM2200 MagicMedia 256AV). So far no joy! snd-nm256 seems to come closest to working. If I set force_ac97=1, the module loads with the encouraging dmesg output: nm256: Mapping port 1 from 0x2709a0 - 0x27ec00 And aplay /home/family/wavs/curly.wav gives: Playing WAVE '/home/family/wavs/curly.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: pcm_write:1265: write error: Input/output error ...close, but still no sound. ------- 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) 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 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. I get som options by going through the legacy ISAPnP section of alsaconf, loading seems to proceed without incident, but an attempt at aplay results in the same set of "no such device" errors. Incidentally, in the BIOS I've selected custom audio settings with the following values: SB I/O Address: 220 WSS I/O Address: 530 Adlib I/O Address: 388 Interrupt: IRQ5 1st DMA Channel: DMA 0 2nd DMA Channel: DMA 1 Does this list of parameters give any clue as to which chip I really have? Another clue: When I run alsaconf and it searches for sound cards, it finds both the nm256 and the opl3sa2 - strange? Much obliged for further troubleshooting help! - Jabez > -----Original Message----- > From: Takashi Iwai [mailto:tiwai@xxxxxxx] > Sent: Tuesday, June 05, 2007 7:09 AM > To: J. McClelland and C.
