[gentoo-user] DVD: Video->Yes, Audio-> But actor can be heard speaking!

[gentoo-user] DVD: Video->Yes, Audio-> But actor can be heard speaking!

[meino.cramer]

Hi,

I've got a mysterious (at least to me ;) effect on system:
When playing DVDs with different players (vlc/mplayer)
video and audio seem to be ok.
With one exception:
I only /see/ the actors moving their mouths...there his
not a single voice audible.
Background sound and everything else is fine.

I tried to increase the volume of "all suspicious"
levels of alsamixer and checked for muted channels
but no success.

I recompiled mplayer and vlc -- no effect.

System:
Linux 3.10.12 #1 SMP PREEMPT x86_64 AMD Phenom(tm) II X6 1090T Processor AuthenticAMD GNU/Linux
media-libs/alsa-lib 1.0.27.2  (-alisp -debug -doc -python ABI_MIPS="-n32 -n64 -o32" ABI_X86="64 -32 -x32" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python2_7")
and two simple speakers (stereo) via simple earphone jack

What is going on here? ;)

Thank you very much for any help in advance!

Sounds like your channel mixing is misconfigured. Unfortunately I can
only give you that pointer, but not how to dereference it. ;-)
The player thinks you have some kind of surround system, so you only
hear two out of x channels.

alsamixer (from command line) should show if ALSA is configured for
multichannel mode and give the option to change to plain stereo.

HiFrank,

thanks for your help! I will try to use it as *help. :)

Whats interesting with all that is: "previously" (read "before 
that problem") everyhing works fine.
And then ...once in a sudden... "something" had shuffled the
channels.

Is there any /sys/... or /proc/... entry to which I could shout "stereo"
to switch back to good 'ole stereo instead of this surround stuff ?

Best regards,
mcc
