[alsa-devel] [FIX]: No SPDIF out from MacBookPro 6, 2, since 2.6.36

[Mohammad Bahathir Hashim]

Hi,

Problem : No SPDIF since 2.6.36
HW : MacBookPro 15" HiRes (mid-2010)
Audio : 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series
Chipset High Definition Audio (rev 06)
HDA codec : Cirrus CS4206

This simple patch will bypass the errata workaround for CS4207, and I
able to use the SPDIF (Toslink) out again.

Suggestion : Make a conditional expression to load the errata
verb/code if the driver detects CS4207.

Thank you.
