[ALSA] hda-codec - Implement auto-mic jack sensing on Samsung laptops

Implemented the auto-mic jack sensing for Samsung laptops with AD1986A
codec chip (model=laptop-eapd).

The hardware uses pin 0x1d and 0x1f for the internal and external
mics, respectively.

The discussion around this patch appears to be here: http://thread.gmane.org/gmane.linux.alsa.devel/50989/focus=51457

Anything we can do to help solve this problem?

Can you get alsa-info.sh output of old version with the change above and of the latest version? Run the script with --no-upload option and attach the generated files please.

Also, it'd be helpful to open a bug entry in bugzilla.kernel.org, too...

thanks,

Takashi
