I have pulseaudio working on my headless Pi3 with a bluetooth speaker.

However, if the speaker is powered off and then on, although it automatically reconnects through bluetooth (as seen by bluetoothctl), the pulseaudio no longer lists it as a sink.

I have to use bluetoothctl to disconnect and (re)connect the device. Only then will pulseaudio (re)list the bluetooth speaker as a sink.

Am I missing some set up or configuration?

I have not solved my problem, but I use the script below to reconnect the device to pulseaudio.

Code: Select all

#! /bin/bash
if ! pactl list sinks short | grep bluez >/dev/null;
then
    echo bluez sink not found, attempting to disconnect-reconnect;
    while ! pactl list sinks short | grep bluez >/dev/null;
    do
        echo loop begin
        bluetoothctl <<EOF
disconnect FC:58:FA:B8:1D:46
quit
EOF
        sleep 10
        bluetoothctl <<EOF
connect FC:58:FA:B8:1D:46
quit
EOF
        sleep 10
    done
    pactl set-default-sink bluez_sink.FC_58_FA_B8_1D_46
    pactl set-sink-volume bluez_sink.FC_58_FA_B8_1D_46 32000
else
    echo bluez sink found
fi
