[mythtv-users] ac3 Issues/Questions

[Norm Dressler]

Hi all,

I've been using spdif out with no problems when not using AC3.  When I
set the switch in the setup to pass ac3 a few things happen.  First, I
get a consistent -300ms sync issue and secondly, when I switch to just
listening through my tv rather then my spdif out, I get the digital
static noise through the TV.  I can fix that by changing the audio
source in the menu but...

1) Is there a way to set the -300ms sync in the system settings
somewhere?  

2) Is there a way to set the default audio to non-ac3 and perhaps set a
button on my remote for turning on ac3?

I also see occasionally write underruns -- I can't find a cause for
these.  It's not regular enough for me to track down.

Any help is appreciated.
