Summary:                    Center channel and 32-bit emulation broken when
upgrading alsa-lib from 1.0.8 to 1.0.9 on nForce 4 system
Description: 
I'm running AMD64 gentoo on an nforce4 system, audio is nVidia CK804 with
ALC850. I can emerge the newest alsa-driver package (1.0.9b), but when I
upgrade alsa-lib to 1.0.9, three things happen.  First, my 32 bit sound
applications, like mplayer32, don't work with alsa anymore.  Second, the
center channel on all 5.1 sound goes out.  Third, the a/v synchonization
on mplayer gets hosed using alsa (oss emulation still ok.)

Those mplayer options do nothing to fix the problem.  The bug is in
NFORCE.conf.  Somebody decided to break it for alsa-lib 1.0.9 for unknown
reasons.

Narrowing the problem down to this file took several hours.  At least one
other person (bug # 1206) has the same problem.  I've also found the bug
on an AthlonXP nforce2 board.  My conclusion:  It's likely that nobody
with an nforce motherboard has functioning surround sound in Linux right
now.  

How did this happen?  Was there no TESTING before these changes were made?
 End users (who have no clue how to debug this kind of stuff) will never
be able to straighten this out.

So are you volunteering to buy me an Nforce2 motherboard?

Otherwise, please fuck off.
