I don't know if this is the problem or not,but in the past pluseaudio
had to be disabled.If it wasn't it would create the exact problems you
are exhibiting .. If you have pluseaudio enabled try removing it and see
if that helps...
Here is how i have my frontend logging setup..
Use this script:
#/bin/sh
mythfrontend > /var/log/mythtv/mythfrontend.log 2>&1 &
1. Make an empty text file in /var/log/myth mythfrontend.log
2. Put the script some place in your path :echo $PATH
3. Make the script executable..
4. Put the command to run the script in a launcher or automate the
launching how ever you see fit....
