Some channels get lost with output to jack

[yurivict]

When I play a movie where the audio is described as dts 6ch 48000Hz to jack (-ao jack), some sound doesn't play.

Some channels get lost?

mpv-0.26.0 on FreeBSD

Did you try --audio-channels=stereo?

Need to see log. Not sure how Jack works exactly, but I imagine it's accepting all 6 channels but you don't have it set up to mix that down, in which case @zc62's solution should work.

Same here with 0.27.2 and -ao pulse. --audio-channels=stereo does not help. vlc plays the some file through pulseaudio correctly.

$ mpv foo.mkv
[...]
 (+) Audio --aid=1 --alang=fre (*) (ac3 6ch 48000Hz)
[...]
AO: [pulse] 48000Hz 5.1(side) 6ch float
$ mpv foo.mkv  --audio-channels=stereo
[...]
 (+) Audio --aid=1 --alang=fre (*) (ac3 6ch 48000Hz)
[...]
AO: [pulse] 48000Hz stereo 2ch float

It seems like I have voices in both L and R but sound effects only in R.

Jack has absolutely nothing to do with pulse.

This seemed related to the issue as I have maybe the same symptoms with another audio output plugin. I'll open another issue if instructed to do so.

stale issue.
