Enable bluetooth headset microphone support in Ubuntu 20.04

Jekson

There is no microphone selection option in the general audio settings interface. Only the notebook's built-in microphone is displayed. There is a selection for headphones, i.e. headphones with a microphone are connected to the system. I can hear the sound.

Here in the penultimate line I see that headset-input not available

    headset-input: Headset (priority 0, latency offset 0 usec, available: no)

how to make the headphone microphone available for selection?

Simple fix. That profile gives good sound NO MIC. Change to the HSP profile not as good sound but both sound and mic.

In theory, you should just go to settings and:

  1. Select in Output your bluetooth device
  2. Select in Configuration the HSP profile instead of A2DP
  3. Now in Input you would see your bluetooth device!

But this doesn't seem to work in 20.04.

=> So follow instructions in https://atish3604.medium.com/solved-bluetooth-headset-mic-not-working-detected-in-ubuntu-20-04-86a5236444d0 (also shown on Use Bluetooth headset with microphone (HFP) in Ubuntu 18.04 but with a mistake as of August 2023).

Now, you will be able to choose between

  • Handsfree: lower quality but both input/output
  • Headset: high quality but only output

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
