Recently, I bought bluetooth headphones, Redmi Buds 3 Pro. I can't use them to record sound or make phone calls because the apps don't use the microphone of the headphones.
According to this review (as online proof for the reader) https://www.techadvisor.com/article/722813/xiaomi-redmi-buds-3-pro-review.html the headphones do have microphones.
There's an app called mi buds m8 with which you can control them but there's no difference. I also tested it with another set of headphones, jlab jbuds, with which it doesn't work either.
Is this a bug in grapheneos or aosp? How can I proceed from here?
