I need to add a delay to my digital audio to sync it with the digital TV.
Any recommendations, that don't include listening to the TV speakers?
Are there AV amps with variable delay on the SPDIF (coax or optical)
inputs? Standalone boxes? Or just build one with a couple of ICs
such as http://focus.ti.com/docs/prod/folder...t/tpa5052.html ?

Sorry, not an answer to your question, but I have the opposite - I need to
delay the video :-) I started thinking about if it was possible, but then
came to the conclusion even if I could manage to sync sound and pictures at
one point, it would probably still drift over time because there isn't a
master clock controlling the two.... thoughts anyone?

I find that the best way to change the sync between sound and vision on
digital TV is to switch to another channel for a few moments, then back
again. The sync relationship will be changed. Do that a few times and at
some point you will likely end up with barely adequate sync.

I guess, though that it would not be difficult to make a box with a
couple of bucket brigade delays in - one each for video and audio. A
single rotary knob could adjust the delay in each with max video delay
at the left and max sound delay on the right. For digital TV as it is at
the moment, a 10 second range should just about cover it.
