Should I be asking you about the old snd_hda? 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
r...@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).
[st...@aire ~]$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: 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
