From dafcaaf86a77c086ed663eb25da1ca42800e171c Mon Sep 17 00:00:00 2001 From: Ricardo Cerqueira Date: Wed, 6 Sep 2006 06:25:38 -0300 Subject: V4L/DVB (4613): Unmute/mute saa7134 when opening/closing the audio capture device. This patch should enable unmuting the audio device when opening it (and posterior muting when closing it), doing away with the need for unmute ioctls or v4lctl usage.
