Hey there, if you are able to reproduce this again, could you also include your voice diagnostic info? To obtain it:
  1. First enable Developer mode: fluxer://settings/user?tab=advanced_settings&section=advanced-settings-developer
  2. Click on your user at the bottom left of the app
  3. There will be a new option called "Copy voice diagnostics"
For screensharing and voice call issues specifically, this information is very helpful for troubleshooting. Ideally, you copy this info while in the voice call while this issue is happening. Unfortunately I tried following your steps and this did not happen for me. I tested with Stable Desktop 2026.1006.171735, Web 2026.1008.22643, Linux 7.2.9-200.fc44.x86_64 (x64), Electron 44.4.1, Chrome 152.0.7977.78, Node 24.21.0, Locale en-US and I'm on Fedora 44 with KDE Plasma.

The "trivial fix" in the name of the second file is indeed pretty trivial and refers to literally this: I open KDE sound settings and click the radio button for my headphones to make them the default audio output device. So that apps (including Fluxer) send their sound to my ears for me to hear again. Additional info: I asked a person if they could hear themself in my screenshare right after I started it and deliberately delayed fixing the bug, they said they could not hear themself (just like I couldn't hear them either). I figured that might be a useful test. Also, feel free to DM me on Fluxer to arrange a call where we could try to help fix the bug.
