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?

An experimental patch is attached. Give it a try.
It won't fix the problem of channel swapping.
This is also what I don't figure out yet. On older ICH chips, the
surround channels are swapped on alsa-lib. But, ICH4 or newer don't do

The fix isn't difficult. The configuration for each card is found in
/usr/share/alsa/cards directory. Change "surround51" definition in
ICH4.conf just like ICH.conf, using route plugin.

This is also what I don't figure out yet. On older ICH chips, the
surround channels are swapped on alsa-lib. But, ICH4 or newer don't do
this because the bugreports have suggested they work without swapping.
And now you report that it's not...
The fix isn't difficult. The configuration for each card is found in
/usr/share/alsa/cards directory. Change "surround51" definition in
ICH4.conf just like ICH.conf, using route plugin.

The following issue has been set as RELATED TO issue 0001521.

Project: ALSA - driver
Issue ID: 1501
Category: PCI - intel8x0
Reproducibility: always
Severity: major
Priority: normal
Status: new
Distribution: Fedora Core 3
Kernel Version: 2.6.14-rc5-gac9b9c66

======================================================================
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?

An experimental patch is attached. Give it a try.
It won't fix the problem of channel swapping.
