From ce22e03e62fd37fb2612abb7af1c66cc17038606 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 11 Jan 2008 17:38:35 +0100 Subject: [PATCH] [ALSA] hda-codec - Don't build boost controls for digital mics The ALC auto-probe creates mic boost controls automatically for the probed pins, but it assumes that they are analog mics. The digital mics have no boost controls and must be skipped.
