#243745 — Problems with videos playback for my user

I'm on Debian sid, using pipewire (just in case that makes any difference). Since a few hours my user is not able to playback videos anymore.

All browsers and mplayer in general behave like this: they do not play just the "video" part, but they normally play any sound tracks the videos come with. They play just a few starting frames of the video and then the video freezes, while sound keeps playing correctly as if video was playing too.

vlc plays the video correctly, but it plays stuttering sound like there were a lot of xruns.

xine is a mix of the others, as it plays both video and sound, but they both stutter a lot.

Everything was working ok until a few hours ago. Then I installed Steam, but I'm not sure that's the cause of the problem and I suspect it is not, because Steam was installed system-wide and other users on the same system do not have any video playback problem. Also Steam installation did not update pipewire, which is the same 0.3.42 version that was working like a charm a few hours ago and it is still working like a charm for other users on the same system.

I use Xfce, while other users use Gnome, but I've already tried logging out and logging back in with Gnome with my user and the problem is the same.

All this happens regardless of the video being online or downloaded offline.

Any clues?

Any or all of of these:

- Check CPU usage.
- Uninstall Steam
- reboot

Thanks, nice try, but, besides I've cleared all three steps just in case (CPU always below 5% while playing videos), none of those can explain why video playback still works correctly for all the users except mine.

Since I needed videos to play, I had to workaround the problem. I logged in as root, renamed my /home/lucio directory to /home/lucio-old, created a new /home/lucio directory, copied over my data, .bash*, .config/google-chrome, .config/xfce*, .thunderbird and some other folders and now videos do playback correctly even with my user. That shows without a doubt that something was broken in my home directory: I just can't imagine exactly what.

As your examples show, the culprits are usually in your dotfiles.
When I first start to use a new Debian version, I generally
quarantine the more complex ones, let the first run of the software
create new ones, then compare the two versions and/or reinstate
them as appropriate. Sometimes it means manually patching the new
version with the modifications made in the old version.

Cheers,
David.
