Can't use bluetooth headset in HSP/HFP mode - ubuntu 20.04

I have a logitech wireless headset that can work in 2 different modes: High fidelity stereo audio (A2DP) without microphone and headset (HSP/HFP) with microfone.

The A2DP mode works, but when I try to switch to HSP/HFP the headset mutes and any background media freezes until I go back to A2DP.

This is the dsmeg output I get when I switch modes:

[   92.294393] input: Logitech Wireless Headset (AVRCP) as /devices/virtual/input/input41

PC specs are

Acer A515-54g (Bios v1.17 - lastest)

WIFI: Intel WIFI6 AX201

Intel Core i5 10210u

Dual boot with windows 10 (fast boot disabled)

EDIT:

ACPI errors can be caused by driver problems. The intel AX201 card is a very new one and the system does not detect it properly (as I asked in here). May be the issues are related somehow.

Solution 1:

I've been experiencing this issue as well. There is a confirmed bug for pulseaudio and bluez. Please report that it affects you: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1878194

Solution 2:

I am experiencing the same issue just after moving from 19.10 to 20.04.

When the bluetooth headset is connected it is automatically configured as HSP/HSP but it does not work with this configuration (in 19.10 it did).
