[mythtv-users] No audio on MythMusic

[Josu Lazkano]

Hello all, I am having audio problem on my father MythTV. He can not
play audio files since yesterday, there is no any software update
since 2 month, so this is strange.

When he goes to play a music file there is no track progress bar, and
there is no sound.

This is what he gets when he select a song to play:

2012-03-03 14:32:01.011 ScreenSaverX11Private: DPMS Deactivated 1

And this is the full log when he start the MythMusic plugin:

I just have SSH access to the system, so I can not test, just watch
the log files.

Is there something wrong?

This is the mythfrontend version:
