Hi Dimitris,
Thanks for reaching out. It sounds like only one app can use your audio at a time, and others get cut off. This is often caused by exclusive mode settings or driver issues.
Try these quick steps:
Turn off exclusive mode
Right-click the sound icon > Sounds > Playback tab
Select your default device > Properties > Advanced tab
Uncheck both exclusive mode options
Check volume mixer
Right-click the sound icon > Open Volume Mixer
Make sure all apps are unmuted
Update or reinstall audio drivers
Open Device Manager > Sound, video and game controllers
Right-click your audio device > Update driver
Or uninstall and restart your PC
Try a different output
Switch from Bluetooth to wired or built-in speakers to test
Check app settings
Some apps like Zoom or Discord may take over audio—check their audio settings
Glad that it solved now.
