From 9085009683dd46d95105eda14efa8bda403b459f Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 5 Aug 2007 08:02:45 -0300 Subject: [PATCH] V4L/DVB (5998): ivtv: no need to mute the audio input When changing channels the audio has to be muted. This is done by calling CX2341X_ENC_MUTE_AUDIO and by muted the audio input. The latter is not necessary and is now removed.
