alsa-project/alsa-ucm-conf pull request #821 was opened from oortcomet:

The ALC4080 codec in NVIDIA DGX exposes the front microphone as the dedicated "Front Mic - Input Jack" terminal. Use this terminal instead of the indexed "Mic - Input Jack",index=1 control, which PipeWire rejects and therefore cannot use to track front-mic availability.

This patch redefines Mic1 according to the codec firmware with the front mic's terminal name.
