Troubleshooting
Setting and keeping bluetooth profile for headset
We want to use the profile sbc sbc_xq for our BT headset Sony WH-1000XM3.
- Set the profile manually - profile should be persistent on reboot / reconnect.
- In principe WirePlumber should remember the last selected profile.
- See [1]
# See available profile and device id with 'pactl list'
pactl set-card-profile bluez_card.38_18_4C_4B_6A_3A a2dp-sink-sbc_xq
- Configure profile
- When using pipewire-media-session, the default profile could be selected in bluez-monitor.conf, but this file no longer exists with WirePlumber.
- (UPDATE - Archlinux - Pipewire) Edit /etc/wireplumber/bluetooth.lua.d/51-bluez-config.lua (or ~/.config/wireplumber/bluetooth.lua.d/51-bluez-config.lua):
bluez_monitor.properties = {
["bluez5.enable-sbc-xq"] = true,
["bluez5.enable-msbc"] = true,
["bluez5.codecs"] = "[sbc sbc_xq]",
}
Crackling / Stuttering audio
This applies in a VM. Not sure these apply when PipeWire is run on the host.
