set-default-input

name	set-default-input
description	Set the default Pipewire audio input (source / microphone) right now. Use for one-off mic switches; for "always prefer this mic when connected" use microphone-preference-rules instead.

Set Default Input

Switch the current default microphone.

Steps

1. Resolve the ID via list-audio-devices if the user named the device by description.
2. Set:

   wpctl set-default <source-id>
   

3. Confirm with wpctl status — the chosen source should be marked default.

Quick level sanity check

After switching, verify the new mic actually picks up audio — call mic-level-check for a few seconds of RMS readings, or run:

wpctl set-volume <source-id> 1.0
parecord --device=@DEFAULT_SOURCE@ --record-time=2 /tmp/miccheck.wav 2>/dev/null

When to escalate to a persistent rule

If the user is repeatedly running this skill for the same device ("always pick the Jabra when it's there"), suggest moving to microphone-preference-rules so Wireplumber handles it automatically on connect.
