Speaker gives noise when playing simultaneously from Bluetooth and other source

[scholzri]

Description

When playing music through LMS, Spotify, or AirPlay and then starting playback from another device via Bluetooth, the audio streams interfere with each other or something, resulting in distorted sound with crackling and noise.

It would be helpful to have a software option that automatically stops or ignores playback on other sources when receiving audio through Bluetooth.

2. Plugin Version: 8.5.2
