Today I connected to my gear4 bluetooth speaker with profile headset_head_unit and it is constantly humming at low volume.

The humming stopped when issueing the command: pactl set-card-profile 0 off

maybe this is related to: https://askubuntu.com/questions/292786/static-background-noise-while-using-new-headset So I will see if load-module module-udev-detect tsched=0 makes a difference. ... I have tried this 0971f74fce6e6b001e610761989c92a8a8a63ac9 but it didn't make a difference, so I reverted the changes
