As workaround a mix between Oliver's solution and this in the duplicated thread (https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1871794/comments/25) worked for me on Ubuntu 20.04 / kernel 5.4.0-42-generic / MSI Prestige 14
I removed from my system /lib/firmware/intel/ibt* and copied /lib/firmware/intel/ibt* inside linux-firmware_1.183.2_all.deb (http://archive.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.183.2_all.deb)
Didn't have to make any changes to /etc/pulse/default.pa but reverted the audio configuration to default by removing ~/.config/pulse
