Desktop app 18.7.10 - Could not start audio source

[Terry_S]

I've come across a few threads handling this notification (eg https://www.3cx.com/community/threads/could-not-start-audio-source-with-v18-desktop-client.83401/), but none seem to provide a definitive solution.
We only work with the desktop app and verified the microphone permission in windows 10 (build 19043).
Out of 5 days days, on average 3 days this problem pops up on a few devices.
Nothing to see in the logs (appdata) or eventvwr.

I've tried reinstalling, reconfiguring but it remains the same.
Rebooting the computer (HP Compaq Elite 8300) resolves it, until it inevatibly happens again (same day, 2 days later at max).
These are domain controlled computers, but we do not control microphone through GPO.
Server version 18.0 (managed through our cloud partner).

Any suggestions?

Hi!

The latest version of the 3CX Desktop App is v18.8.508 and is bundled together with 3CX V18 Update 3 Hotfix 1:


If you haven't done so already, update your 3CX Server to this version. Then your Desktop App(s) should give you a notification that there is an update available. Install it and see if the issue remains.
