The combination of "Line-In As Surround" and "Duplicate Front" is already
weird.

Attach /etc/asound.state and /proc/asound/card0/codec97#0/* files for
debugging.

I too have the same problem with my Nvidia CK8 based sound card, and have
uploaded the requested files.
 
I am running Gentoo Linux with 2.6.10 kernel, and alsa 1.0.8
My LFE and Centers are reversed, along with the right rear missing.
Everything surround (that is not the LF and RF) are also alot softer.

I have full 5.1 with 1.0.6 that is in the kernel I am running, except it
is still mixed way too softly.

Thanks!

One more thing I think I have *found* using speaker test.
Under both 1.0.8 and 1.0.6 the LFE/CENTER and Rear Surround jacks seem to
be swapped.
Oddly enough in 1.0.6 Doom3 has correct surround, while in 1.0.8 it
doesn't work correctly.

Correction : 1.0.6 isn't correct either. I only noticed that I was using
the OSS analog 5.1 from doom3, not the alsa. Even with 1.0.6 alsa surround
doesn't work properly.

nforce2 built in sound on an a7n8x-e deluxe motherboard
am also experiencing this issue on 2.6.10. Very frustrating, its a
showstopper on migration from windows to linux. Will attach
/etc/asound.state and /proc/asound/card0/codec97#0/* files tonight.

I think that my issue report # 902 describes the same problem, although I
have examined that it's the rear socket's channel second not working
regardless of mixer settings. Could anyone check if it's so?

Exact same problem here, right rear surround speaker doesn't work in a 4.0
setup with the "Line-in as Surround" option set.
Works fine with kernel 2.6.10, but 2.6.11 doesn't. Also tried plain alsa
release 1.0.8 and recent checkout from CVS. These also don't work.
asound.state the same in both cases (2.6.10 compared against the others),
also the ac97#0-0+regs only differs in some volume settings. But also
tested it by setting the exact same register settings.

System:
Asus A7N8X-X
Debian Unstable
Kernel 2.6.11-ck1

Can you try the latest CVS version?

----------------------------------------------------------------------
 tiwai - 03-09-05 18:43 
----------------------------------------------------------------------
Don't forget to update both alsa-driver and alsa-lib!

----------------------------------------------------------------------
 jor - 03-09-05 19:24 
----------------------------------------------------------------------
Yes, tried new CVS checkout and recompiled the kernel modules. It's working
again.
I guess the "Fix stereo mutes on Surround volume control" CVS diff on
ac97_codec.c does the trick, Many thanks. :)

no luck over here:
asus a7n8x-e deluxe
fedora core 3
not sure I built it right.
I did from my home directory as root
mkdir alsa
cd alsa
cvs -q -f -z3 -d  ":pserver:anonymous:@cvs.sourceforge.net:/cvsroot/alsa" 
co -P alsa-driver alsa-kernel alsa-lib

./configure didn't work... something is wrong with the documentation....
so tried
./cvscompile
and
make install
 did this for both alsa-driver and alsa-lib per suggestion, did I need to
do it in a particular order?

----------------------------------------------------------------------
 slammer - 03-10-05 11:55 
----------------------------------------------------------------------
Have you read "Compilation from CVS sources" section in alsa-lib/INSTALL
and alsa-driver/INSTALL  ?

----------------------------------------------------------------------
 slammer - 03-10-05 13:17 
----------------------------------------------------------------------
I confirm it too. CVS version fixes my issue reported in 902 so I guess
it's the same bug ;)
Great job guys!

I was reading the howto's off the main page, hadn't occured to me that the
INSTALL would contain entirely different instructions. Anyhow, as you can
see, I "did it right" according to the install instruction in INSTALL and
still have the problem. I am running kernel-2.6.10-1.770 for fc3, looks
like this may be the problem as those of you reporting it fixed are
running 2.6.11 of some sort. FC3 hasn't released that yet. I could roll my
own, I know it "shouldn't" break anything, might do that when I can find
the time. I have a wife and family though, and they miss me since I
started this linux thing.

----------------------------------------------------------------------
 slammer - 03-10-05 23:28 
----------------------------------------------------------------------
Yeah. Me too should get life... such things just eat me and digest with
bones. Anyhow I know it's none of my competence but, since this was fixed,
people would really use at least rc version soon.

----------------------------------------------------------------------
 tiwai - 03-16-05 14:49 
----------------------------------------------------------------------
Yes, now 1.0.9rc1 was out.  So, please give it a try.

----------------------------------------------------------------------
 stephenv - 03-16-05 16:41 
----------------------------------------------------------------------
tiwai, Thanks for not closing this out. I will test with rc1 tonight and
let you know my results.

----------------------------------------------------------------------
 jor - 03-19-05 18:06 
----------------------------------------------------------------------
yes, 1.0.9rc1 also works, and I see the patch in 2.6.11.5. So I'm happy
again :)
