'Twas brillig, and Mohammad Bahathir Hashim at 26/10/10 06:08 did gyre and gimble:
Hi, I want to use MacBook Pro (6,2) Mid-2010 15" with GNU/Linux all the time. IMHO, GNU/Linux provides me the best performance and flexibility for audio and video.
Problem 1: No SPDIF when using Linux 2.6.36, but it working fine with 2.6.35
Problem 2 ? : xFront Speaker -> controls the woofer sound level Surround -> controls the left and right channel speakers' sound level.
Both kernels 2.6.3[56] show the same problem/feature :).
My guess at the fix:
ALSA: hda - Fix wrong SPDIF NID assignment for CA0110
http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=commit;h=24b...
(the base64 encoding of your alsa-info attachment didn't come through in a friendly way so I didn't bother decoding it, and hence this is just a guess)
