I recommend to use for this Pipewire. On pulseaudio not tested this method. Add new file sudo subl /etc/wireplumber/wireplumber.conf.d/50-bluez.conf With monitor.bluez.properties = { bluez5.enable-msbc = true } Then systemctl --user restart pipewire pipewire-pulse wireplumber sudo systemctl restart bluetooth TLDR I wondered for two weeks why the method described in the official Arch Linux guide, using the WirePlumber configuration file at <strike> /etc/wireplumber/bluetooth.lua.d/51-bluez-config.lua </strike> and syntax like <strike> bluez_monitor.properties = {</strike> It doesnt'work Instead, use /etc/wireplumber/wireplumber.conf.d/50-bluez.conf and syntax described in the beggining of post and will be fine
