This issue shows how fragile the interaction can be between the ALSA UCM layer, PipeWire/WirePlumber, and SOF firmware when hardware behavior diverges slightly from assumptions baked into existing configs. Even with modern audio stacks, if the UCM definitions don’t correctly represent headphone and speaker paths, desktop audio handling (auto-mute, port switching, jack detection) breaks down for end users. https://geometrydashlite22.github.io
