From f672f65a1c15b04e09d25701a8b5be47bad9376a Mon Sep 17 00:00:00 2001 From: David Henningsson Date: Tue, 5 Feb 2013 12:06:02 +0100 Subject: ALSA: hda - Fix phantom jacks on VT1708 The VT1708 has no unsol event capability, and polling is set using the "Jack Detect" alsamixer control. In order not to create phantom Jack controls, temporary enable jackpoll during build_controls.
