Hello,

I'm having issues with the internal microphone on an Asus R553 (or S551) laptop.

With the boost set to zero the microphone works but the level of the
recording is very low.
If I try another boost setting I don't get any signal anymore.

I have uploaded alsa-info data here :
http://www.alsa-project.org/db/?f=55b7fb0b4998757d099addae0a411e6a7cebc079

This is on a Linux 4.0 kernel.

Any help is welcome,

Regards,

   Simon
