From 37d57dd3b3ac7045d7fd044127e2299f55fc22b2 Mon Sep 17 00:00:00 2001 From: Ricardo Cerqueira Date: Wed, 6 Sep 2006 10:25:38 +0100 Subject: Unmute/mute saa7134 when opening/closing the audio capture device. From: Ricardo Cerqueira 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.
