[mythtv] No DVD audio--missing codec?

Scott Traurig straurig at comcast.net
Tue Oct 21 00:16:45 UTC 2008


DVD playback results in no audio. Internal player, 0.22 build 16578, Ubuntu
8.04. 

It ran fine in Ubuntu 7.10. 

The internal player plays the video just fine, accesses DVD menus just fine,
all controls work OK, just no audio. 

Live TV and recorded TV work OK both video and audio.

DVDs play fine in Totem or Mplayer.
 
I'm thinking a codec went missing in the upgrade to 8.04, but how to tell
which one and how best to reload it? (libdvdcss2 went missing but I caught
that one).
 
Below are some relevant snippets of the mythfrontend log (set to "verbose
all").
 
Thanks for taking a look,
 
Scott
