[mythtv-users] No audio strangeness

[Damian]

Hi all,

For some reason, I'm getting no audio through my new MythTV system.

I'm having some tuning difficulties relating to my USB tuner, but that 
can't really be the cause, as videos files playing through MythTV are 
silent too.

Sound is working on the system. If I exit MythTV and go online, I can 
watch a YouTube vid and hear the sound.

Also, within MythTV, if I go to the sound setup section, I can hear that 
'interference' type sound to test my audio setup.

I still can't hear anything on playback though.

Any ideas?
Damian
