I'm having this same problem and ignoring it for some time (no sound), but on FreeBSD aire.franks-development.dyndns.biz 6.4-STABLE FreeBSD 6.4-STABLE #9: Sat Dec 13 18:25:36 MST 2008 root@aire.franks-development.dyndns.biz:/usr/obj/usr/src/sys/GENERIC amd64 instead of current. I read the warning: A few Hardware/OEM vendors tend to screw up BIOS settings, thus rendering the snd_hda driver useless, which usually results in a state where the snd_hda driver seems to attach and work, but without any sound. In the man page, and I suspect that may be my problem. Chipset is Intel. I played with the bios, but only got it to be worse (snd_hda not detected at all). [steve@aire ~]$ cat /dev/sndstat FreeBSD Audio Driver (newpcm) Installed devices: pcm0: <Intel 82801G High Definition Audio Controller> at memory 0xfdff8000 irq 16 kld snd_hda [20071129_0050] (1p/1r/1v channels duplex default) Is there any further info that would help? I've been limping along on a usb dongle and it's a bit sad ;) Thanks, Steve
