I'm trying to use my headphones with my Ubuntu 13.10. My headphones are Nokia BH-905i, which can be connected via Bluetooth or green+pink wires.

If I use bluetooth, voice quality is terrible or microphone doesn't work. If I try to choose "Headset" option from In and Out tabs in Sound Settings, they're disabling each together.

In Out tab, I'm using "High sound quality A2DP", because it betters voice quality.

How could I get my microphone working? Sound out works fine.


By design, the Bluetooth A2DP profile is unidirectional. We can not use a microphone unless our headset and adapter were capable to be paired simultaneously on both HSP, and A2DP protocol, or the application switches from A2DP to HSP on demand.

I've just installed a solution for Bluetooth not selecting the mic on my Bose QC35 II on Ubuntu 16.04 LTS.

Since the internal mic on my Samsung laptop is too close to the fan audio sounds like inside an airplane for all participants in a videocall.

The solution is Blueman that adds functionality for Bluetooth.

Install it: sudo apt-get install blueman

I had to restart network-manager (sudo service network-manager restart) after WiFi stopped working (could be unrelated, but hey better have it just in case).

Blueman GUI

I can now switch to Headeset Head Unit (HSP/HFP) and choose the headset mic in Sound settings

Sound settings - input

Still a bit of a hassle when it does not switch automatically (like Android does) but it's still better than being in a Jumbojet storage!

    The question was on getting the microphone to work in A2DP mode, which AFAIK still is not possible. Using a mic in HFP mode is rather trivial and should work OOB without any additional applications needed. If you needed blueman in addition to get it working there may be an issue with your audio setup in the fist place. – Takkat Jan 31 '18 at 12:48
  • Well Takkat, it's a known problem with using BT mic in headphones on Ubuntu so it's not an audio setup for the mic problem... And sorry I accidentially downvoted your answer yesterday, could not reverse it. =( – Valross.nu Feb 1 '18 at 13:44
  • en.wikipedia.org/wiki/… - it is inherent to the Bluetooth profile definition. Nothing we or any other OS could do to overcome this - but you are quite correct in that issues with HFP-mode sadly still exist. – Takkat Feb 1 '18 at 14:23
  • I disagree here because most OS do make the switch between the two protocols without user interaction. As pointed out Android or Windows or ios switches automatically, where Ubuntu does not... So there is a solution in place for automation between the two... – Valross.nu Feb 2 '18 at 23:59

Already commented above that HFP is two-way and A2DP is one way.

But they also use different links: https://stackoverflow.com/questions/40033827/what-is-the-difference-between-acl-and-sco-link-in-bluetooth (or updated versions of those)
