Status in linux package in Ubuntu: Incomplete Status in pulseaudio package in Ubuntu: Incomplete 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: https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/169428 ===================================================== 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.
