I’ve started experiencing a weird issue with the Plexamp flatpak on Linux recently. Basically when I launch the app and first try to play a song, there’s no audio output and the playback seekbar will keep skipping backwards/forwards by 1 second. The only way I can fix this is to go into the setting…

It’s been fixed in the release from today.

Linux Mint 22.2, can confirm the issue and the workaround to change audio device.

Can we get some acknowledgement from Plex about this issue, given that this seems to affect a large group of Linux users? I’m happy to help test any potential fixes.

Appears to be fixed in 4.13.0. I had to switch it back and forth one last time but it seems to stick now. Thanks to whoever at Plex fixed the bug.

Where are you seeing 4.13.0 available? Discover Store still has 4.12.4 as the latest.

Correction: I still have the issue again after a reboot so it looks like it’s not fixed yet, and 4.13.0 may have been pulled from flathub. If anyone at Plex is reading this and working on it, I’m happy to help test a potential fix before it’s released.

Can confirm. Issue still here. I think the cache simply reset itself on the first launch after 4.13.0 upgrade. I had the impression that it worked well more than once, but now I have the problem every time I launch it. Besides, I have the problem on Gnome or KDE, so it’s probably related to PipeW…

having the same issue with version 4.13. quite annoying. downgrade to 4.12.3 seems to help, but as the app always updates itself it’s not even a permanent workaround.

I’m also seeing this on 4.12.4. In case it matters, my system has pipewire 1.4.9

Same here. Using the latest Appimage.
