Hello.
I've been trying to get the microphone of my bluetooth headphones (Soundcore Life Q30) working and, as expected, it only works on HSP/HFP, the problem is that the audio quality is really bad, changing the codec to mSBC should fix it, but instead i get a loud buzzing noise that hurts my ears, from what i could gather, this is a problem with the kernel on 5.16 and downgrading to 5.15 should fix it.
