…systems When only a single audio sink is detected, this adds fallback logic to attempt swapping the ALSA card profile between Analog and HDMI. This gracefully handles logic on hardware with unified chips that mutually exclude ports in PipeWire/PulseAudio. Additionally, automatically pause and resume playback via playerctl around profile swaps, since rebuilding the audio node tree briefly causes media players to pause out of safety.

Description
On systems with unified audio cards (like the HDA Intel PCH), the HDMI output and the Analog (Headphones) output are mutually exclusive ALSA profiles. Because of this, only a single sink is ever exposed to PipeWire/PulseAudio at any given time. As a result, the default
omarchy-cmd-audio-switchscript incorrectly fails with "No audio devices found" instead of allowing the user to switch to the unplugged/inactive profile port.Changes:
If only 1 sink is available and it belongs to a card currently in
analog-stereoorhdmi-stereomode, gracefully commandpactl set-card-profileto forcefully switch to the other one.playerctl(play/status):Changing ALSA profiles destroys and recreates the audio nodes in PipeWire/WirePlumber behind the scenes. This drop-off causes apps (like Media players and Browsers) to hard-pause playback as a safety measure. The script now records playback state before switching profiles, sleeps briefly to let the soundcard re-initialize, and re-triggers
playerctl playto unpause the stream seamlessly.
