From 6020c008dfe6b68626de7de7b4fa99982e345c86 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 19 Nov 2007 11:56:26 +0100 Subject: [ALSA] hda-codec - Revert volume knob controls in STAC codecs Volume knob controls with STAC codecs seem to cause problems with some devices. Volumes change very slowly or silent suddenly. It's likely due to conflict between the software and the hardware volume knob setup. Since we'll have a virtual master control in future, it's safer to remove this control completely right now.
