[mythtv-users] momentary audio drop when screensaver deactivated

[Mark Perkins]

Mythbuntu: MythTV Version : v0.27.6-27-g3783dc8

For quite a while I have been getting an intermittent momentary loss of
audio of approximately 1sec during recording playback and livetv. It is not
in the recording as rewinding and playing the scene again does not reproduce
the audio drop in the same place. I have just realised that these audio
drops very consistently align with this info message in the frontend (-v
playback) logs:

ScreenSaverX11Private: Calling xscreensaver-command -deactivate

The odd thing is that I don't get an audio drop every time that message
occurs (the message seems to occur quite regularly every 50seconds with -v
playback). However having just watched a tail of the log with a show playing
- everytime I get an audio drop I simultaneously get that message.

At face value it appears that the screensaver is getting deactivated every
50sec, should that be happening? Or should it only happen once each session?
Any theories as to why this would be causing a momentary audio drop?
Any suggestions on what to do to fix or what further information might be
required to diagnose properly?
Can I permanently disable the screensaver so mythfrontend doesn't need to
worry about it?

The hardware is a Zotac Zbox ID41 - Atom processor with NVidia Ion graphics
if I recall correctly I can pull up the full specs if it is believe to be
relevant.
