I recently bought a Jabra Elite 75t to connect to my computer. I did the following:

  1. Entered Pair Mode with my headphones
  2. Opened Settings -> Bluetooth
  3. Clicked on "Jabra Elite 75t" to pair the device
  4. Device was paired

When listening to youtube I intermittently get choppy audio with this device. I never experienced this with a wired setup before.

I tried the following fixes but nothing has worked; there is still some choppiness to it:

The headphones seem to work fine on my Android phone, so I'm not sure what the issue is with Ubuntu (I'm on 20.04). This is the output from running lspci -knn | grep Net -A3; lsusb on my terminal:

Anything I'm doing wrong or advice on how to solve this?

Run in a terminal

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

and reboot.

That should fix BT and 2.4 GHz Wi-Fi problem.

  • Yes it seems to have worked with very few problems so far! Thank you very much. Can I ask what exactly this fixes?

    This command disables BT-Wi-Fi coexistence algorithm that doesn't work well with some Intel devices.

My solution is probably related to the first answer in this thread. After trying a couple of configurations I found on the net, nothing worked for me. Then I thought maybe my WiFi signal is clashing with the Bluetooth signal, and voila - it worked.

Just switch off your WiFi adapter and it should work. However, if you need to use your WiFi then I suspect the problem is actually with network discovery feature. If you can somehow kill this feature and connect directly to known networks, the Bluetooth should work.

    If both frequencies are provided, pinning your wifi to 5.5GHz solves the problem as well :) Dec 29, 2022 at 11:17

Really simple solution to try:

bluetoothctl scan off

This stops the adapter from scanning for more devices. Especially in bluetooth-busy areas this can overwhelm the adapter.

If the Bluetooth window is open this means it's scanning for devices. Closing the bluetooth connection window can be equivalent to bluetoothctl scan off depending on your distro. It is on Fedora 35.
