Original GitHub issue: https://github.com/netblue30/firejail/issues/2333

So I realized that mpv, by default, does not control pulseaudio levels but instead controls its own internal volume level and I rebound 9 and 0 to control ao-volume to fix this (in ~/.config/mpv/input.conf). When I run mpv directly with my profile, everything works really well. So far so good. I do an ln -s /usr/local/bin/firejail /usr/local/bin/mpv so it will be sandboxed by default.

Now, I start using mpsyt (mps-youtube) and create a profile for it. This one includes my mpv profile and whitelists a couple of additional things (namely, mpsyt complains a lot if I don't enable DBus and I additionally whitelist the config file and binary). Here is where things get interesting. If I keep the ignore nodbus, mpv reverts to its software mixing defaults for the keybindings. If I comment that line out, mpv controls the pulseaudio volume as I configured it but mpsyt is semi-broken.

Okay, fair enough. Not quite sure why, but let's play along. If that line is the issue, then firejail --ignore=nodbus /usr/bin/mpv <file> (or adding ignore nodbus to the profile file) should also revert to software mixing, right? Nope. That works just fine and mpv continues to control the pulseaudio volume.

Does anyone know why on earth this should be the case? I've included the relevant profiles here.

Original GitHub issue: https://github.com/netblue30/firejail/issues/2333 So I realized that `mpv`, by default, does not control pulseaudio levels but instead controls its own internal volume level and I rebound `9` and `0` to control `ao-volume` to fix this (in `~/.config/mpv/input.conf`). When I run `mpv` directly with my profile, everything works really well. So far so good. I do an `ln -s /usr/local/bin/firejail /usr/local/bin/mpv` so it will be sandboxed by default. Now, I start using `mpsyt` (`mps-youtube`) and create a profile for it.

That works just fine and `mpv` continues to control the pulseaudio volume. Does anyone know why on _earth_ this should be the case? I've included the relevant profiles here.
