If you run:

sudo systemctl enable bluetooth.service

It may help
https://www.studioteabag.com/science/dell-venue-pro-linux/DV11P/

Could try the 5.4 kernel
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.1/

See if it helps

You don't need the "lowlatency" debs

the problem seems to be between the Sony headset and Linux. The connection between my external bluetooth speaker and the pc works perfectly. I will try to borrow another bluetooth headset for testing.

I think I have found the reason for the problem:
– Bluetooth speakers using A2DP only work fine.
– Bluetooth headsets using HSP/A2DP do not.
