Hello again!
There is a Flutter application. After publishing and installing with Snap application cannot start a system process, but in IDE all works good.

I had found similar post , but it is not marked as resolved
Could you help to resolve this problem please?
Looks like you are trying to run pactl, is it in your stage-packages? pulseaudio-utils looks like is missing.

pactl is the native system command, not separated package

you need to add the audio-playback plug to get access to the pulse socket of the host and as sergio says, you can not run the pactl command from the host, just add the pulseaudio-utils stage package to have it available in your snap …
EDIT: oh, i see you are calling list sources, assuming you want to actually use the sources you find, that will also require the audio-record plug … note that this one needs to be manually connected after snap installation …

I added these plugs and the stage. That’s working! Now I have new exception:

As I understand for this needed the process-control plug, but it included

@mmyr just out of interest - what kind of flutter app are you packaging?

i am pretty sure killall is not included in the base snaps, you would have to seed it via adding psmisc to your stage-packages or use pkill instead, that is there by default.
