name	set-default-output
description	Set the default Pipewire audio output (sink) — speakers, headphones, HDMI, Bluetooth, etc. Use when the user wants to switch where system audio plays right now, without writing a persistent rule.

Set Default Output

Change the current default sink (audio output). For persistent "always prefer X when connected" behaviour, use microphone-preference-rules (analogous skill exists for outputs — extend that pattern).

Steps

1. If the user named a device by description (e.g. "the Jabra"), call list-audio-devices first to resolve the ID.
2. Set the default:

   wpctl set-default <sink-id>
   

3. Verify:

   wpctl status | head -40
   

   The chosen sink should now have * next to it.

Moving currently-playing streams

Setting the default sink does not move already-running streams by default on every system. To move them too:

for stream in $(wpctl status | awk '/Streams:/{f=1;next} f && /│.*├/ {print $2}' | tr -d '.'); do
  wpctl move "$stream" <sink-id>
done

A more reliable approach is pw-cli with move-node, or use pactl move-sink-input <stream-id> <sink-name> for each PulseAudio-style stream.

When the user asks for "output also goes to X"

That's not a default change — that's a combined/loopback sink. Defer to the route-on-device-connect skill, which can set up a module-combine-sink style routing so audio plays to two outputs simultaneously.
