[ale] DVD sound broken after patching CentOS 6.6

[Bob Toxen]

THANKS to all three who replied with helpful info.

When I have it working again I'll report what it took to fix.  I note
that with identical Centos 6.6 on both my desktop/tower and
Thinkpad laptop, I have some DVD on the Thinkpad but not the
tower (but the tower sound card passes sounds generated by the system,
which is puzzling.

More soon.

Bob
