, namely both Orca and the two
instances of brltty (one to follow the virtual consoles and one to
follow graphical terminals) were all connecting to the speech-dispatcher
server.
I am now encountering two issues that I believe are independent. I am
happy to report bug if/where appropriate but would like to ask for help
in diagnosing and solving the problem before doing so.
Issue 1: users can't play sound.
My understanding of the problem: Pipewire's socket,
/run/pipewire/pipewire-0, belongs to root.nogroup and is neither
readable nor writable by others. If I run the following command:
chmod o+rw /run/pipewire/pipewire-0
users become able to play sound again, but this has of course to be
repeated after each boot.
