From 7a3c6e67be916c3ca24b5ef0acdc5e32ab4e3559 Mon Sep 17 00:00:00 2001

Subject: [PATCH 08/87] ALSA: hda - Disable dynamic-power control for VIA as
default
commit b5bcc189401c815988b7dd37611fc56f40c9139d upstream.
Since the dynamic pin power-control and the analog low-current mode
may lead to pop-noise, it's safer to set it off as default.
