[alsa-devel] snd-hda-intel (Cirrus Logic CS4206): MacBookPro6, 2 : No S/PDIF with Linux 2.6.36C
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 :).
TIA.
Here I attached alsa-info.sh's result for both kernel.

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 :).
Could you please download http://www.alsa-project.org/alsa-info.sh and either upload the results, and reply back with the URL to the results, or attach the resulting text file to your reply? We need a bit more information about your hardware before we can help you any further.

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)
