I just wanted to confirm I did get this working. (sort of)
I have it set up now so that I get seperate speaker/headphone controls. Not exactly what I'd hoped for, as I know it works in windows properly, but at least I can now mute the speakers and use the headphone, which is what I wanted in the first place.
It's as simple as:
1) Install alsa 1.0.13
(Well, this wasn't so simple. It's not part of the fedora repository and I had to find all the 1.0.13 rpms doing searches.)
In total, on FC6 x86_64 I had to install:
2) edit /etc/modprobe.conf and do the following:
- options snd-hda-intel index=0
+ options snd-hda-intel index=0 disable_msi=1
Walla, all working.
(Now, if anyone knows how to either get A) power management or B) stop crashes when ctrl-alt-fx'in I'm in business!)
