[alsa-devel] [PATCH] snd-hda-intel: Jack Mode changes for Sigmatel boards

Fri May 29 18:41:38 CEST 2009


The (hopefully) final version of the patch.

This patch changes Line In as Out Switch and Mic In as Out Switch to
enums for consistency, and causes all mic and line in ports to be probed
and controls to be added appropriately.
