Linux jamulus version feedbacks because MUTE ME is not muting me....

Starting with Jamulus for Linux. Sounds get killed by feedback killer because extreme feedbacks occure via Microphone. Even while MUTE ME is pressed (or not pressed, doesn't matter)

Start Jamulus on Linux

Mute sound when mute button is pressed

**Screenshots**

Linux
AME="TUXEDO OS"
VERSION="24.04.3 LTS"
ID=tuxedo
ID_LIKE="ubuntu debian"
PRETTY_NAME="TUXEDO OS"
VERSION_ID="24.04"

**Version of Jamulus**

3.11.0

**Additional context**

Start by reproducing the MUTE ME behavior on Linux with Jamulus 3.11.0 on the reported TUXEDO OS environment, then trace the microphone and feedback path involved in muting. Done means pressing MUTE ME prevents the microphone from producing feedback while the issue remains reproducible conditions are covered.
