Bug description:
Hello,
I have a problem - after one of the updates (sorry for being not precise - I
can only track it back to the time I have been surely listening something on
headphones - it has to be beginning of this year because last time I have been
listening more on my SB Live for sure was in last one-two weeks of February
2019 - I have suddenly lost "stereo" on my headphones.
I have speakers connected to on-board sound card and headphones connected to
SB Live Value for few years, so I did not mess with outputs or something - one
day I changed Audacious output to SbLive in pavucontrol (as usually) and that
time the sound was weirdly filtered.
I have found that this must be "surround upmix" which I do not need and tried
to disable it,
enable-remixing = no and the same for "LFE remixing" in
/etc/pulse/daemon.conf did not work.
It does not matter what configuration I choose in pavucontrol- analog stereo
duplex, "analog stereo output", "Analog surround 5.1" or 4.1 - for all "Analog
output" scenarios the output is the same except for "mono" (no sound at all).
I have tried do "skip" pulseaudio choosing "ALSA" output in Audacious + the
alsa configuration for stereo but the upmix is still present.
I have followed the old thread in Launchpad Answers:

=====================================================
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...
=====================================================
I have next tried to follow the path from ubuntu sound troubleshooting
guide, I have purged everything, installed back and now I'm here
again with this "upmix" on SBLive! Value.
Thanks in advance for help :)
Tom
