Kooha freezing when recording microphone audio

[ArnaudLier]

System Info

• Kooha version 2.0.1
• Distro information and version Fedora 36 Silverblue
• Desktop Environment information and version GNOME 42.2
• Display Server Wayland
• Flatpak? Yes

Describe the bug When starting a record with microphone audio enabled, Kooha will freeze and the "Kooha is not responding" popup will appear. After a few moments clicking on "Wait", Kooha finally starts the recording but stopping the record freezes Kooha for good (I've waited some time and it's still not unfreezing).

To Reproduce Steps to reproduce the behavior:

1. Select whatever options you want but with microphone audio enabled.
2. Start recording
3. Contemplate the beauty of the universe while waiting for Kooha to unfreeze.

Expected behavior Be able to record microphone audio without problems.

Additional context

Depending on the run, different types of errors occured, each code block is one run of the program. On the two last runs, the recording screen with actual time didn't show up at all.

I think the problem also killed Firefox as it wasn't responding and there was some problems while trying to play videos during some of my runs. Restarted my system and now Kooha seems to work fine :thinking:

I've started to find this isue with the freezes in the mic recording, but video seems fine. And Im not getting any Kooha is not responding, but mic seems to get progressively worse.

Actually, the video isnt very smooth, you can see the mouse spaz out when I move it around or open windows pop in and out, so there's some issues as well there.

Thanks for reporting! Closing this then since it was not an issue within Kooha.

This may be that issue https://github.com/SeaDve/Kooha/issues/106
