Ubuntu – Ubuntu 15.10 bluetooth headset playback problem


My bluetooth headset works fine with phones, windows. But when I connect it to my Ubuntu 15.10, the audio starts stuttering after a few seconds. Sometimes it skips or goes fast. In "Sounds", I have selected the "High Fidelity Playback (A2DP Sink)" profile.

I am using wifi on the same system.

Output of lspci -knn | grep Net -A2; lsusb:

The problem must be with radio interference. Wi-Fi and BT use same frequencies in 2.4 GHz band.

There is a technology called "bluetooth coexistence" that allows to avoid interference.

Unfortunately bluetooth coexistence does not work well in Broadcom wireless proprietary linux drivers.

And there is no other alternative driver for this adapter.

I am afraid there is no solution for that, except replacement of the wireless adapter.
