I have an Ubuntu 22.04 LTS and I have some problems with sound in my bluetooth headphones(MAJOR IV). When I play any videos in the browser I have intermittent audio interruptions.I changed my browser, but It didn't help. I changed audio profile from A2DP Sink to HFP and the sound stopped intermittent, but the quality of sound became very bad. I tried to disable the bluetooth continuously scan devices by commands "bluetoothctl" and then "scan off", but I got an error: org.bluez.Error.Failed. So my problem is still unresolved :( I hope you will help me! Thanks for your attention!

P.S. It is the output of lspci -knn | grep Net -A3; lsusb:

The problem is that 2.4 GHz W-Fi shares the same band as Bluetooth.

Run in a terminal

sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi bt_coex_active=N"

and reboot.

The setting can be reverted by

sudo rm /etc/modprobe.d/iwlwifi-opt.conf

But a really good solution is to use 5 GHz Wi-Fi.
