Audio capture doesn't work with non-default sink

[Slater91]

Hello! I have noticed that when a non-default sink is selected, or if the sink is changed after OBS is opened, audio isn't recorded at all (and I noticed the hard way: I recorded a whole interview with no audio...). This is reproducible 100% of the time and with any sink. Sometimes the issue is seen when changing the sink after OBS is started, sometimes even if it is changed before OBS is started, which makes understanding what's going on really difficult.

I am using PipeWire 1.0 with WirePlumber (no difference is seen when using pipewire-media-session) from the PipeWire PPA related to this project on KDE Neon (based on Ubuntu 22.04).

Here are the OBS logs:

Here is the output of pw-dump:
pw-dump.json

Here is a screen recording that showcases the issue:

untitled.mp4

Any idea what might be going on?

I can't reproduce this. Were the sources in the video set to "Default"?

[Slater91]

Yes, they were set to "default". Nothing changes if I manually select the source.

Are you on the latest version? (There's no way to check, sorry, if you don't know just install the latest one)

Sorry for my late reply. I have just updated the plugin and on the latest version it still displays the same behaviour.
