My question is, how do we know that the rt715 codec has connected internal microphone to this input? I believe that this should be covered in the machine specific code (runtime check), not in the codec code. #if CONFIG is not sufficient here.
I have moved this part code to the local definition of rt715_set_amp_gain_put and removed from rt715_priv. new code will be like this in V4.

The whole LED trigger mechanism for the sound is covered in my LED generic code : https://lore.kernel.org/alsa-devel/20210211111400.1131020-1-perex@perex.cz/
