[ale] DVD sound broken after patching CentOS 6.6

[DJ-Pfulio]

Work with aplay for now, until it works.  Then you can deal with mplayer and
other stuff.

aplay -l

if that shows stuff, you have the right drivers. If not, start looking for the
device and driver with

sudo lshw -C  multimedia

Sometimes it is a simple device/file permissions thing or an old config from
prior releases - clean out the ~/.asound stuff and perhaps the /etc/alsa stuff.

I've almost never had good luck with pulse-anything. Find it easier to purge
from the system. The output from aplay -l tells you which devices to setup in
the /etc/asound.conf - so decide if you want analog or digital output and which
device you want to get it ... speakers, headphone, HDMI, digital coax or toslink
... there will be a different device (should be) for each.

Plus don't forget to verify that auto-mute isn't enabled through alsamixer.  I
hate when that happens.

Anyway - hope that is clear enough to get started.
