Higher quality Bluetooth audio input with Pipewire and mSBC

Installing Pipewire on Fedora 33

Follow the instructions here:

Run the following command to install pipewire (will remove pulseaudio):

sudo dnf install --allowerasing pipewire-pulseaudio

Reboot your machine.

pactl info should now list Server Name: PulseAudio (on PipeWire 0.3.x).

Enable mSBC codec support for HFP

Instructions from here:

The default audio codec in Fedora 33 for HSP/HFP is CVSD, which is an 8 kHz codec. mSBC is a 16 kHz codec. mSBC is disabled by default because it’s not supported on all Bluetooth input devices. To enable it, edit either ~/.config/pipewire/media-session.d/bluez-monitor.conf or /etc/pipewire/media-session.d/bluez-monitor.conf with the following contents:

properties = {
  bluez5.msbc-support = true

Then restart the pipewire service with

systemctl --user restart pipewire.service

In your system settings for audio, you should now have an mSBC codec available for the HSP/HFP protocol.
