From 004934ecaf3436173d936a555ec1b131a2867f73 Mon Sep 17 00:00:00 2001 From: David Henningsson Date: Thu, 28 Jun 2012 15:40:17 +0200 Subject: [PATCH] alsa-mixer: Always turn "Inverted Internal Mic" off Some devices have inverted right channel, so when you add left and right, the result is silence, or very faint sound. In recent kernels (3.5, perhaps also 3.4) these are starting to be marked with a special "Inverted Internal Mic" capture switch. While we might want to add some reverse summing mechanism in the future, for now, we just turn the thing off to avoid the problem of recording silence.
