How to configure sound system to use stereo on bluetooth headphone and use internal microphone?

za flag

I am using PX7 Bowers & Wilkins bluetooth headset, it has an internal microphone. I understand that it is impossible to send high fidelity playback when I use the microphone of the headset, but ubuntu simply doesn't use the internal mic, and does not send stereo whatever I do. How to resolve this issue?

So you already know (apparently) that it's either HFP (mono + mic) or A2DP (stereo, no mic). What is the question?

@ChanganAuto The issue is that the second option does not work. The audio is always mono, and I am unable to change othe Mic to the onboard version and use change the audio strea to A2DP. The question is how to resolve it.

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.
