I have conected a bluetooth headset (N35) to the computer in Ubuntu 21.10, and I can hear them fine with A2DP. But if I select HSP or HFP, they don't work, I can only hear a strange noise, and the microphone doesn't work.

I've seen similar questions with this topic, but the answers doesn't work for me. Anyone can help?

20.10 is no longer supported and a newer version with a newer kernel might fix 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.
