kad77:

Let's discuss the direction of the Linux page; how it should be organized and updated, etc.

Many bits of interesting info have been removed, because they aren't directly relevant to using gimli's loader method.


Christian:

My ATV is set up w/ gentoo. Alsa is installed, but the volume is extremely low, almost no sound at all. I tried compiling ALSA as part of the kernel or modules, I tried loading the ALSA modules w/ the four or five options for the ALC882 given at the alsa-project.org website - nothing.

If anyone has succeeded w/ sound on our little box - please tell everyone how, maybe post your kernel .config? Thanks...

davilla:

For 2.6.20.6 kernel, the easier way (no patching required) it to add to /etc/modprobe.d/alsa-base

options snd-hda-intel model=3stack-dig

If you are running the most recent alsa release, it has ALC885 additions (for the MacPro) so use

options snd-hda-intel model=macpro

Analog sound output is still weak but much better. The ALC885 pin def needs some work.

A patch for analog audio has been created, see the forum (http://forum.awkwardtv.org/viewtopic.php?f=23&t=167&hilit=&start=70)
