[Solved] VLC no longer plays sound on right speaker

Recently VLC stopped playing sound on the right side. Both on my speakers and my bluetooth headphones.

- Output mode is set to stereo.
- Same files play audio fine on both sides using mpv
- other applications also play sound on both sides

I'd been hoping this was a bug but recent updates haven't fixed it.
Anything else I could check for the cause? (I'm using pulseaudio on kde)

Post

pacmd list-sink-inputs

while playing something for starters and/or look through/delete ~/.config/vlc/vlcrc to make sure you don't have some faulty vlc config

Playing the same video both in vlc and mpv at the same time:

                module-stream-restore.id = "sink-input-by-media-role:video"

Fresh vlcrc makes no difference.

CLearly this is the problem:

volume: front-left: 65536 / 100% / 0,00 dB,   front-right: 3221 /   5% / -78,51 dB
                balance -0,95

Any idea how to fix it?

Re: [Solved] VLC no longer plays sound on right speaker

pactl set-sink-volume 84 100%,100% #just use whatever sink index the inputs command gives you

should work, otherwise use pavucontrol or the right click advanced option menu in KDE's plasma-pa mixer, use the corresponding "adjusting all channels" to split the channel into it's two components and bump the right one back up
