Hello,
I've just landed on FreeBSD planet, so things are still a bit confused, =
but I'm trying.
I have a Dell Inspiron 640m (Core2Duo T5500) with Intel 82801G ICH7 =
integrated sound device.
I get no particular error or warning (see various outputs below), but I =
have no sound at all (either in KDE or in console # cat anyfile > =
/dev/dsp), I just can't figure it out.
I've been trying to get sound working, with the hdac drivers from Mr =
Ariff's page. I "made" hdac.ko, it didn't work. I patched it with both =
current.diff and snd_RELENG_6_20070312_150_lowlatency.diff.gz (I've got =
to be honest : I didn't really know what I was doing)
There were errors : hunks failed, and it seems it didn't find hdac.c to =
patch - I had not redirected the output, so it's lost, unless there's =
some kind of log ?
I tried various setups and entries in /boot/loader.conf - nothing =
worked, so I removed all sound related entries, rebooted, and simply=20
# kldstat hdac
Here are the outputs :

I also tried setting vchans to 4 but no use. As I said, I'm new to =
FreeBSD, so I may very well misunderstand the way the system works.
And I'd really like to get this sound to work, as I'm supposed to use =
this computer to go and sell music around...
