Hi Risto,
I don't use audio/visual stuff on my Linux machines much so think of me
as a newbie in that area.
I understand the business about blacklisting things and putting other
things into /etc/modules. I've done that for other projects.
But I'm having trouble figuring out what "headphone detection" is and
what it's supposed to be good for?
Can you give me more explicit instructions for testing. I.E. fill in
the missing stuff in this checklist:
1) Install a yaboot-fixed Squeeze-powerpc on my PowerMac3,4 machine.
2) Do the blacklist and /etc/modules changes and reboot.
3) download with wget your "alsa-modlues" .deb; then install it with
"dpkg -i <...>.deb" then reboot again.
4) locate an mp3 file from somewhere? (Got a favorite? So far as I can
tell, there aren't any useful ones included as part of the Debian
installation.) Play it (how? -- does alsamixer do that? I don't see
any controls for playing a file in the alsamixer screen... Should I run
rhythmbox at the same time?)
5) Then what? Look for something (what?) to change as I plug a pair of
external speakers in and out the external-headphone jack?
6) Report the results to you and the powerpc mailinglist.
7) Do you want the same experiment done with the blacklist reversed?
Thanks!

Hello Tom, Rick, and the others,
I've tried to add headphone detection support to snd-aoa for
PowerMac3,4. The package is available at:
http://ristosu.wippiespace.com/pub/alsa-modules-2.6.32-5-powerpc_1.0.23+dfsg-2+2.6.32-29_powerpc.deb
It can be installed with 'dpkg -i' and gets loaded by reboot. It
contains both snd-aoa and snd-powermac (already somewhat tested). The
latter is loaded when put into /etc/modules, in which case
snd-aoa
snd-aoa-codec-tas
snd-aoa-fabric-layout
snd-aoa-i2sbus
snd-aoa-soundbus
should be blacklisted.
Try it, and tell me how it went.
Risto
