Make sure that you use alsa-driver-snapshot tarball instead of 1.0.21
released version.  There are many fixes since 1.0.21 release.

This isn't supported yet as we have no hardware information.
Likely one of GPIO pins corresponds to the LED on/off.  You can try
hda-verb to change the GPIO data bit.

It's not about the sound driver but the input layer, as you can find.
You can defien the scan code 0xe014 by yourself.
