[Feature request] Switch playing streams

[BloodyAltair]

How about to add an function to switch already playing streams? I've wrote something like that on pacmd:

touch audio_state
SPEAKER="0 analog-output-speaker"
SPEAKER_SH="DEVICE_NAME"
HEADPHONES="1 analog-output-headphones"
HEADPHONES_SH="DEVICE_NAME"

if grep -q speaker "audio_state"; then
            pactl set-sink-port $HEADPHONES
            OUTPUT=$HEADPHONES_SH
            echo "headphones" > audio_state
            timeout 2 kdialog --msgbox "Switched to external audio device"
else
            pactl set-sink-port $SPEAKER
            OUTPUT=$SPEAKER_SH
            echo "speaker" > audio_state
            timeout 2 kdialog --msgbox "Switched to headphones"
fi
# Set default
pacmd set-default-sink $OUTPUT >/dev/null 2>&1

# Switch playing streams to default device
for playing in $(pacmd list-sink-inputs | awk '$1 == "index:" {print $2}')
do
         pacmd move-sink-input $playing $OUTPUT >/dev/null 2>&1
done

Seems like duplicate of #5 , and seems like obsolete with the PipeWire behavior.
