audio-switch.ps1

<#
================================================================================
  audio-switch.ps1  -  Switch the default audio output + move running apps to it,
                       then show a fast AMD-style overlay.

  Reads optional "audio-switch.config.json" next to this script (created by
  setup.ps1). Falls back to built-in defaults if missing.

  Usage:
    powershell -ExecutionPolicy Bypass -File audio-switch.ps1 1      # slot 1
    powershell -ExecutionPolicy Bypass -File audio-switch.ps1 2      # slot 2
    powershell -ExecutionPolicy Bypass -File audio-switch.ps1 list   # list devices

  Requires svcl.exe (NirSoft SoundVolumeCommandLine) next to this script.
  Run setup.cmd once to download it and pick your devices.
