since I upgraded to 22.04 I haven't been able to configure bluetooth speakers as microphone+speaker for video calls and other.
I can use them as hi-fi speakers, but when I try to configure them as "Freehand unit (HFP)" audio becomes crackling and noisy (not sure if in English this option is also named Freehand unit).
I have tryied some solutions related to pulseaudio and also this one but non of them worked.
This other solution seems to complex for me and I didn't try.
My devices are detected, they work as hi-fi play, but not as microphone+speaker. In other laptops or mobile and can use them properly.
