Summary:                    intel8x0 surround channels missing and swapped
Description: 
By default, the front channels are OK, the rear channels come out on the
center/LFE jack and the center/LFE channels don't come out at all.

Using ICH5/AD1985 (Intel P865PERL motherboard).

Anomolies found: double-rate slot (DRSLOT) is set to 7,8 instead of the
default
10,11 (register 0x20=0400 instead of 0).  After setting 0x20 to 0, the
rear
channel jack starts working.  RL/RR and Center/LFE are still swapped.

I would assume the swappage was hardware, but the Center and LFE volume
controls
affect the speakers on the Center/LFE jack which would indicate the driver
is
incorrectly routing the signals.

Setting DR slot to 7/8 is intentional, as found in ac97_codec.c.
The question is whether this still has influence even DRA bit is off on
extended status regsiter.
Could you check whether reg 0x2a bit 1 (0x0002) is off during playback of
48khz (or less) samples?

0x2a, bit 1 is off: 0:2a = 05f1
