pulseaudio module-tunnel-sink times out on connect

  • PipeWire version (pipewire --version): pipewire Compiled with libpipewire 0.3.42 Linked with libpipewire 0.3.42
  • Distribution and distribution version (PRETTY_NAME from /etc/os-release): OpenSUSE Tumbleweed
  • Desktop Environment: KDE
  • Kernel version (uname -r): 5.15.8

Description of Problem:

module-tunnel-sink appears to simply hang and then error out on attempted use

How Reproducible:

Every time, at least on my system.

Steps to Reproduce:

  1. Enable module-native-protocol-tcp (in this case I do connections both ways so this is on both machines)
  2. Attempt to use module-tunnel-sink to connect to the remote pw instance

Actual Results:

in syslog and the connection hanging (along with other audio) until it times out

Expected Results:

sinks appear and work over the network as expected

Additional Info (as attachments):

I've looked for a way to do this natively in pipewire (with remotes?) but the documentation Ive found is either nonexistent or so sparse that its unhelpful. This MAY be a wireplumber issue. But I'm not sure. The issues occur on the other machine as well if I attempt to do a sink from there. Similar logs of Exec format error etc.
