From 219f47e4f96442a7fe8fb646c59c6730690a9e66 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 20 May 2015 06:56:23 +0200 Subject: [PATCH] ALSA: hda - Disable widget power-saving for ALC292 & co We've got reports that ALC3226 (a Dell variant of ALC292) gives click noises at transition from D3 to D0 when the widget power-saving is enabled. Further debugging session showed that avoiding it isn't trivial, unfortunately, since paths are basically activated dynamically while the pins have been already enabled. This patch disables the widget power-saving for such codecs.
