The following is appended to /var/log/syslog when trying to change profile in pavucontrol: Aug 14 14:59:02 k-laptop pulseaudio[18882]: Refused to switch profile to a2dp_sink: Not connected I'm currently using patched pulseaudio-modules-bt from here: https://github.com/EHfive/pulseaudio-modules-bt. But the problem persists with both packages. The working workaround I found is: sudo systemctl restart bluetooth.service bluetoothctl # list device MACs devices # use a MAC from the list above connect <MAC> After doing this, it is possible to switch to A2DP profile in pavucontrol. But such restart is required each time device is connected.
