Did some reading on the subject. The Sound How-To confirms your suspicisions: Another symptom is sound samples that loop. This is usually caused by an IRQ conflict. The Boot Prompt How-To has information on boot arguments, but they don't seem to work. I tried both "sound=22" and "snd-via82xx=22" (after making sure I had alsa-modules-2.4.27-1-686 installed), but the card gets configured with IRQ 18. Here's the dmesg output: Via 686a/8233/8235 audio driver 1.9.1-ac3 via82cxxx: Six channel audio available PCI: Setting latency timer of device 00:11.5 to 64 ac97_codec: AC97 Audio codec, id: VIA97 (Unknown) via82cxxx: board #1 at 0xE000, IRQ 18 [EMAIL PROTECTED]:~$ cat /proc/cmdline root=/dev/hdb2 ro snd-via82xx=22 Any ideas what else I should try?
