how to disable stereo > 5.1 upmixing

Asked by Rafał Kowina

I'm trying to figure out how to disable stereo upmixing. I've got 5.1 speakers running with Intel HDA soundcard (ALC889a). When I play stereo it's played on all my speakers. Situation is the same on both Exaile and Firefox (youtube). Changing Ubuntu sound settings doesn't do anything. I want to play stereo as a true 2 channel audio, while still having an ability to watch a movie with 5.1, without messing with cables or muting channels in alsamixer. Ubuntu 11.04.

In /etc/pulse/daemon.conf, set enable-remixing=no

Did you uncomment the line by removing the leading ';' and log out/in?

Hello,

i'm on ubuntu 16.04LTS (AMD64, with emu10k1 based soundcard) and since the last update I have similar problem - I have lost ability to listen stereo music on my Soundblaster Live Value (i use earphones).
Even system sounds , web browser content and mp3 files are up-mixed.
Few days ago it was no problem to choose "analag stereo output" in pavucontrol, now it seems that at this output have rear surround channel only (as I suppose, there is "stereo" but vocals are like heard from the other room and there is sometimes reverb as in the bathroom) :/.
I had tried adding "set enable-remixing=no" in both /etc/pulse/daemon.conf and in the home directory configuration file without success.
I have purged pulseaudio but with the ALSA there is the same problem, I have tried purging alsa and reinstalling without effect.
So i thought that it can be emu10k1 driver specific, after digging in the network for solutions I have had tried adding "hint.emu10kx.0.multichannel_disabled " to the module configuration file without visible (or rather soundible ;) effect.
I have tried to check EMU10K1 configuration with aweset, but it gives error message, so maybe the bad magic sits somewhere around?

aweset
/dev/sequencer: No such file or directory

Once again - everything worked fine until the last update. I use xubuntu desktop as my machine is quite old, in despair I have installed unity to find the sound settings / speaker configuration etc and button to "disable all effects" as I have seen somewhere, but there were no such options.

Help me Obi Wan Kenobi, you're my only hope...
