The same device looked almost exactly the same on a 7.1-BETA build, but I
actually had audio output.
I've checked the mixer device, tried muting and unmuting various channels,
all to no avail. The audio devices are created, and every program I've
tried opens them successfully, but I get no actual sound.
I've tried searching around, but I haven't been able to turn anything up.
Is there something I'm missing? Something I should be doing that I'm not?
You are missing new snd_hda man page reading. RTFM. :)
1) Read new man page;
2) Driver provides you two pcm devices for different purposes, so try to use
both (as man page recommends);
3) If your system has several audio connectors - try all of them, they are
not equal any more.
4) Boot with verbose logs enabled to get much more information about your
codec and driver operation (as man page recommends);
5) Connexant audio codecs are rare, so send your verbose output to me, I
would like to see it.

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: 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
