Pulseaudio: use 5.1 for videos and 2.1 for music

Is there any way to automate the process described in the title?

I only was able to make pulse play stereo files with 2.0 (without sub) and movie files in 5.1 by adding "disable-remixing=yes" in daemon.conf
how can i make sub in stereo work and still be able to have 5.1 for music automatically?

Dunno about pulseaudio, but this can be done in ALSA - here's my ~/.asoundrc as an example.

The music player needs to output to the upmixing PCM.

Check this link there a lot of stuff that you can do at command line while running your section and not at your rc.conf. Also check /etc/pulse folder.

Dunno about pulseaudio, but this can be done in ALSA - here's my ~/.asoundrc as an example.

The music player needs to output to the upmixing PCM.

using your config i get this:

➜  ~  speaker-test -D upmix_20to51 -c 2 -t wav

speaker-test 1.0.25

Playback device is upmix_20to51
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
ALSA lib pcm_ladspa.c:1512:(snd_pcm_ladspa_add_plugin) Unable to find or load plugin '(null)' ID 1672, path '/usr/lib/ladspa'
Playback open error: -2,No such file or directory

Unable to find or load plugin '(null)' ID 1672, path '/usr/lib/ladspa'

So install that plugin.

Don't blindly use my config. Also, READ all the useful comments I put inside it
