From 5322bf2790fb91328aac1783bb1963ea3a172bcf Mon Sep 17 00:00:00 2001 From: David Henningsson Date: Wed, 5 Jan 2011 11:03:56 +0100 Subject: [PATCH] ALSA: HDA: Fix volume control indices for Mics (Realtek) If more than one mic is present with different locations, e g "Front Mic" and "Rear Mic", they can use the same index (0), since their names are different. Previous behavior was to have "Front Mic" as index 1, causing it to be ignored by e g PulseAudio.
