It would be good to say which one (kldstat output), but from below I expect you'll have: Id Refs Address Size Name 6 1 0xc5577000 5000 snd_ich.ko 7 1 0xc557c000 1d000 sound.ko > Some info: > > # pciconf -vl > > > > none4@pci0:5:0: class=0x040100 card=0x37301462 chip=0x01b010de rev=0xc2 > hdr=0x00 > vendor = 'NVIDIA Corporation' > device = 'nForce MCP Audio Processing Unit (Dolby Digital)' > class = multimedia > subclass = audio > pcm0@pci0:6:0: class=0x040100 card=0x37301462 chip=0x01b110de rev=0xc2 > hdr=0x00 > vendor = 'NVIDIA Corporation' > device = 'nForce MCP Audio Codec Interface' > class = multimedia > subclass = audio I have: pcm0@pci0:6:0: class=0x040100 card=0x57001462 chip=0x006a10de rev=0xa1 hdr=0x00 vendor = 'NVIDIA Corporation' device = 'nForce MCP-T Audio Codec Interface' class = multimedia subclass = audio I don't have the APU. > # dmesg | grep pcm > pcm0: port 0xe400-0xe47f,0xe000-0xe0ff mem 0xdc180000-0xdc180fff irq 16 at device 6.0 on pci0 > pcm0: > Interrupt storm detected on "irq16: pcm0 nv0++"; throttling interrupt source pcm0: port 0xe400-0xe4ff,0xe800-0xe87f mem 0xe4000000-0xe4000fff irq 21 at device 6.0 on pci0 pcm0: Looks pretty much the same, except that the chipset is slightly different. The important message is the last one: "Interrupt storm". That's the problem; I don't have a real answer, but what version of FreeBSD are you running? It might also help if you can connect the pcm device to a different IRQ from the nv device; but that depends on your motherboard BIOS.
