Modern A/V receivers with HDMI I/O generally have an adjustable delay for
addressing this issue.

My HDTV's *only* output of any kind other than the picture is digital coax
(stereo, not multichannel), which does indeed have the proper amount of
delay for use with a standard DAC.

If I wanted multichannel, then I'd have to use one of the outputs of the
cable box. I've tested some of them and they all cause lip synch problems
unless additional delay is applied.

An AV amplifier would have an adjustable delay feature to bring the sound
into time-alignment with the picture. If the OP wants multi-channel sound
then this is his best option, if he only wants 2 channel stereo then using
the digital audio output from the TV will do the job for a lot less dosh.
