Sound and the 24" iMac

I finally found info on how to make it happen here.

Here's the short version:

• I used Ubuntu 7.10, which has Alsa 1.14, which is a little different.
• Make sure

  options snd-hda-intel model=bbp3

  is somewhere in your modprobe.d files, like in alsa-base.
• Turn on a lot of goo in the mixer.
• Surprisingly the built-in Mic is the digital input!

I now know that XSquawkBox Linux sound does work (but only if X-pane itself is run with --no_sound to allow OSS to open).
