Re: bluetooth audio under pipewire: playback silent?

Hi Peter,

could Pulseaudio be involved? In that case you might try setting bluetooth as its default output, something like this:

pactl set-default-sink `pactl list short sinks | grep -i blue | awk 'BEGIN {FS=" "} {print $1}'`

or in a shell script:

#####
echo "Current PA default sink:"
pactl get-default-sink

NEW_SINK=`pactl list short sinks | grep -i blue | awk 'BEGIN {FS=" "} {print $1}'`

pactl set-default-sink $NEW_SINK

echo "New PA default sink:"
pactl get-default-sink
#####

Cheers,
Marc
