Try turning off the Dolby digital audio when using the Toslink. Dolby
can add about 0.5 seconds delay. DTS audio might have less of a delay
and is worth trying. Toslink does NOT have a lip sync specification
because there is no associated video channel. That might explain why
Panasonic isn't very responsive to the problem. If you want tolerable
(not perfect) lip sync, HDMI 1.3 and 1.4 are the only interfaces with
a functional spec.

The strange noises are definitely not normal and should be
investigated. However, I have no clue from where they originate.
