Hello, I have strange behaviour problems with on-board sound card using snd_via82c686 module. Sound gets somehow distorted and scratchy out of speakers. Here is pciconf -vl output: --snip-- pcm0_at_pci0:7:5: class=0x040100 card=0x33001462 chip=0x30581106 rev=0x50 hdr=0x00 vendor = 'VIA Technologies Inc' device = 'VT82C686/A/B AC'97 Audio Codec' class = multimedia subclass = audio --snip-- and dmesg -a output: --snip-- pcm0: <VIA VT82C686A> port 0xe400-0xe403,0xe000-0xe003,0xdc00-0xdcff irq 5 at de vice 7.5 on pci0 pcm0: <ICEnsemble ICE1232 AC97 Codec> --snip-- dmesg -a | grep "irq 5" reveals: pcib0: slot 7 INTC is routed to irq 5 pcm0: <VIA VT82C686A> port 0xe400-0xe403,0xe000-0xe003,0xdc00-0xdcff irq 5 at de vice 7.5 on pci0 Sometimes output sounds to be slowed down when CPU is heavily loaded.
