Summary: Fixed chip configuration for 5.1 in ALC850 code
Description:
Frustrated by the fact that the 5.1 DVD I just bought had no voices (since
they were on the center channel) I started to dig into it. The details are
in the "steps to reproduce".

Attached is a (very) small patch that fixed it completely on my system
(both the mixer and the channel mix-up). My guess is that the chip was
misconfigured by lack of a bit in the MX76 register. (2 instead of 5 for
bits 6:4)

Ah, OK, I missed the part where you said the patch was based on the ALC850
datasheet.

Maintainers, this patch should be applied for the 1.0.11 release.
