From 32ed3f4640631ab7a4c0bc0f1463cf019d510341 Mon Sep 17 00:00:00 2001 From: Matthew Ranostay Date: Thu, 22 Jan 2009 20:53:29 -0500 Subject: [PATCH] ALSA: hda: Add STAC92HD83XXX_PWR_REF quirk Some revisions of the 92hd8xxx codec's not supporting port power downs in which the using of it causes capture and also randomly playback streams to not function at all. Thus by disabling it by default and adding a option to enable it manually will fix all issue on current and future revisions.
