This should be controlled by platform data and/or the machine driver, not interactively by the user. With some microphone technologies there is actually a risk of damage with higher micbiases.

All this stuff should be TLV.

I'd expect these to be platform data/machine data rather than user control? The speaker wiring isn't going to vary dynamically...

These comments look inaccuate, fs is the sample rate so a divide of 1 would be fs.

ARRAY_SIZE() or a #define or something rather than a magic number.
