(SOUND I810_AUDIO)Allow AC97 re-routing: D845PEBT2 sound from wrong connector

Description of problem:
Sound configuration properly detects the integrated sound chip on the Intel
D845PEBT2 motherboard but no sound is played on normal front channel connection
as in Windows. If speakers are connected to rear channel outputs, sound plays
normally. It seems that 810_audio.o module is not handling 6 channel sound chip
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Actual Results: Chipset is properly detected as intel 810
no sound plays is speakers are connected to normal lime speaker connector. Sound
is played on rear channel (right and left) connector.
Expected Results: Sound should come from lime connector
I also have the Intel D845PEBT2 desktop motherboard, running RH 8.0.94,
and can vouch that the sound does indeed come out of the rear speaker
connector. But it comes out of the front speaker connector with Win/XP.
This particular computer is dual-boot (my kids use it mostly), so its
a pin to keep switching the speaker output.
It sounds like the driver is getting loaded properly. Once loaded, the driver
is sending sound to the wrong output. This sounds like it is a driver problem
rather than a redhat-config-soundcard problem. Transferring.
Seems Windows knows about the odd setup of this boardf and has drivers using non
standard channels. We don't currently support doing that but it seems we need to
look at it eventually

I haven't tried this yet (maybe this weekend), but I see that Intel now has Alsa
sound drivers for their desktop boards here...
From the release notes...
Devices Needing Additional Drivers to Function with Red Hat 9.0: Â· ADI* 1985 AC
97 audio will not function properly after a normal installation of Red Hat 9.0.
Red Hat 9.0 will attempt to install and load AC 97 audio drivers and it will
appear that the audio solution is properly configured when it really is not.
Download the appropriate driver for the desktop board being used and install
them using the instructions provided with the driver.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
