From 6680427791c94e611220a6cb34ae47dac9e3aa98 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 30 Apr 2012 04:58:27 -0300 Subject: [PATCH] [media] mxb: fix audio handling Instead of using custom ioctls use the VIDIOC_ENUM/G/S/_AUDIO ioctls. Also send the same audio to both CDROM-out and line-out. This is what you would expect and anyway, the CDROM-out connector is unlikely to be used these days as it is obsolete.
