Pair Bose QuietComfort 35 with Ubuntu over Bluetooth (2)

Question

(Relating to Pair Bose QuietComfort 35 with Ubuntu over Bluetooth - seems to be "too old to response to")

This is really frustrating!

I am running Ubuntu 16.04 and am unable to get sound in the headphones. I have tried all suggestions above without success. I have had it working before I reinstalled Ubuntu, but unfortunately I have not noted how I made it working then. Now I can pair, at least from the Ubuntu side what it seems, but there is no voice in the headphones indicating that a pairing has been made and the sound is still coming out from the computer's speakers.

Answer 1

I have a similar issue with a bluetooth (BT) headset, my solution was:

• Open bluetooth (BT) manager (it should show a list with all BT defined)
• If yours is not there,
• Set the headphones(hp) to 'discover mode' and run a Search on the BT manager This should discover the hp and they should appear now. They may not connect though, in that case:
• Right-click on the hp name and select headset, this may still not produce sound,
• Right-click again on the hp name, this time there will be a new option, 'audio profile'
• Select High Fidelity Playback (A2DP sink)
• Now open your 'Sound Settings' and select your headphones and adjust volume.

Hope this helps.
