hi, I'm trying to get sound working on my hp pavilion zt1130 with VIA VT82C686A chipset. Here's the relevant info. kernel is compiled with device pcm options PNPBIOS $ cat /dev/sndstat FreeBSD Audio Driver (newpcm) Installed devices: pcm0: <VIA VT82C686A> at io 0xe000 irq 9 (1p/1r/0v channels duplex) $ dmesg|grep pcm pcm0: <VIA VT82C686A> port 0xe104-0xe107,0xe100-0xe103,0xe000-0xe0ff irq 9 at device 17.5 on pci0 I've done MAKEDEV snd0, I can play cd's using cdcontrol just fine, and I can cat files to /dev/dsp and /dev/audio for a short time. dmesg gives some interesting errors. at boot: pnpbios: Bad PnP BIOS data checksum when trying to play an mp3 with mpg123 or splay, I get nothing and this: pcm0:play:0: play interrupt timeout, channel dead I've read the following, which sounds similar to the case for this laptop when I was getting sound to work with linux. Playing a sound made it hang shortly after starting it. Strangely, it got fixed when I patched the kernel to add ACPI support. The problem had something to do with non-compliant ACPI tables in the bios. http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/34942 Has anyone been able to fix this or had the same problem?
