Re: sound on intel imac [solved]

Hello Daid,

Thanks for your reply.

After my post I knuckled down and worked systematically through the
model= options for ALC883/888 and ALC882/885, having gleaned from the
internet that these are most similar to the 889A. The possible choices
are listed in /usr/src/linux/Documentation/alsa/HD-Audio-Models.txt.
Several choices produced sound, but only this (for ALC882/885):

options snd-hda-intel model=mbp3

in /etc/modprobe.d/alsa.conf, followed by running update-modules,

produces sound and turns off the speakers when the headphones are
plugged in.

This was one of the options I tried before posting, having found it
using google, but it did not work. I _think_ I made the mistake of
rerunning alsaconf after editing /etc/modprobe.d/alsa.conf, which of
course erased my edit! Dumb.

Best wishes,
Roger

I had some trouble getting everything working on a newer kernel. I'll
post the solved results of that on this list presently.

If I didn't suggest it, pommed is a nice little daemon for using the
Mac hotkeys. It was doing silly things today, but once I rebuilt and
had the correct kernel settings, all was good.

My sound was going to 0 at around 30% today, which was some
interference between an older kernel and a newer kernel settings.
Startup gave me funny messages about the sound card whenever I'd boot
directly from one kernel into another, and I decided once everything
else was working, if I just switched to the older kernel and back to
the newer one, it could properly initalize itself. It worked! Who
knows with these things..

Let me know if you need any other hardware working, since I've got it
all I think. (Never tested bluetooth, but it shows up, and I deleted
my old IR setup since I switched away from KDE, but it worked.)

Regards,
daid
