I faced the same problem on about 10 new Samsung devices running Android 14

I have the same issue, and I have further information:
When I compile Element's code with targetSdk set to 33, the issue does not happen. Probably Google changed something between targetSdk 33 and targetSdk 34, IDK what.

I can confirm this on a Pixel 6a using GrapheneOS.

This should be fixed urgently as it keeps me from doing hands-off calls.

I confirm this.

@bmarty Hello. Is there any chance that this bug can be patched? Those who that don't know how to downgrade or use GitHub are basically cant use this app calls. I see there are updates for Element X but not for this client.

I can confirm this is still the case on 1.6.22 [40106222] (G-9a4602bf).

Tested on the OnePlus 7T Pro (A14).

Calls are nearly unusable. Including the fix from PR in the next release would be highly appreciated.

This has been an annoyance for quite some time. Whenever browsing to another app or the screensaver kicks in, my microphone is muted. On Element 1.6.22, GrapheneOS build 2024092900 android 14, pixel 6pro.

[dmgartung]

So I tested new released version 1.6.22 and the bug still present in that version.

The changes from this ticket were made a day or two after the 1.6.22 release. They appear to be on an approximate monthly release cycle. I don't see that the PR has been merged yet.
