Bug Description
Binary package hint: alsa-base
In the current alsa-base on Jaunty, the MacBook Pro's soundcard isn't appropriately detected.
This results in no sound and a constant illumination of the SPDIF mode of the headphone jack.
To fix the problem, one must add: "options snd_hda_intel model=mbp3" to /etc/modprobe.
# dmidecode -s system-product-name
MacBookPro3,1
# apt-cache policy alsa-base
alsa-base:
Installed: 1.0.18.
Candidate: 1.0.18.
Version table:
*** 1.0.18.

Attached is the ./alsa-info.sh script AFTER I updated /etc/modprobe. d/alsa- base and sound works.
As an aside, the default volume for "FRONT" seemed to be so low that the volume keys on the keyboard only really matter at the highest few settings (beyond that, the volume was effectively zero, until "FRONT" was cranked up).
