Some laptops have a internal analog microphone that is not setup by the BIOS.

Applied to HG tree.
BTW, are there boards / machines that have both analog and digital mics? Currently, we have "Digital Capture Volume". It was introduced as an alternative volume control for digital mics. But, this seems confusing people a lot because this volume works correctly at 50%, corresponding to 0dB. For systems that have only analog mics, this control doesn't make much sense.
Thus, I would love to make this control depending on the presence of digital mic if possible...
thanks,
