OS: Ubuntu 18.04 LTS
Headphones with bluetooth: JBL T450
PC: Dell Inspiron 5570

When I am watching a movie or listening a music and there is a silence my headphones are muted and just after some sound appears they are unmuted. One of the solutions is to play some sound in the background - then silence in the movie doesn't mute headphones but it's not the solution...
I checked headphones on Windows and they are not muted so I guess there is some mismatch in OS configuration.
Any idea?

PulseAudio has suspended the module after detecting that no audio has been transferred. Disable the module that does so.

To disable loading of the module-suspend-on-idle module, comment out the following line in the configuration file in use (~/.config/pulse/default.pa or /etc/pulse/default.pa):

### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
  • I am afraid it didn't solve my problem. It was only fine just after I reconfigured it like you suggested.

  • I have two profiles in Bluetooth settings for my Headset: High Fidelity Playback(problem with mutting) and Headset Head Unit (NO problems with mutting but sound is terrible).

That's the solution:

$ sudo vim /etc/pulse/default.pa
load-module module-udev-detect ignore_dB=1
