I’m using pipewire on my system which generally works satisfactory. One of my use-cases is that I sometimes su to another user and also want to use audio from there. To achieve this, I added the following section to my pipewire config:
services.pipewire.config.pipewire = {
context.modules" = [
{
name = "libpipewire-module-protocol-pulse";
args = {
"server.address" = [
"unit.native"
"tcp:4713"
];
};
}
];
}
The other user account has PULSE_SERVER=tcp:127.0.0.1:4713 in his shell environment. This has been working until recently, but now I cannot play audio anymore on that other user. I’ve checked the usual suspects, the port is open and the connection is not blocked by the firewall. Here is what pw-mon shows me when I run pactl info as the other user:

It seems as if the connection is marked as restricted. How can I allow this connection to play audio? There seems to be all kinds of media-session-managers around that are probably related to this, but I don’t really understand yet how all of this plays together. But I’d like to play audio in this scenario again. Has anyone got this running and can provide some configuration here? I am using 21.11.
