I noted in a previous thread that Dave Plowman said you can take the
audio (stereo) signal off the back of the TV via Phono sockets
(avoiding delays) which sounded promising for connecting to my Amp.
Are these available on all modern TVs?

It varies wildly in my limited experience. On some the only audio out
is from the headphone socket and on others with RCA connectors it can
either be at fixed line level or vary with the TV volume control and
some others have only audio out as digital on RCA or TOSlink.

My current (Panasonic CRT) TV does have analogue outputs for sound.
However they audible clip/distort loud sounds and add background noise and
hum. My default assumption is to assume analogue outputs from a normal
domestic TV display are rubbish. I'd hope that an spdif output from a new
set would be OK. But given how badly TV makers seem to treat audio I can't
say I'd be surprised if they fouled that up as well! :-/

Fortunately CRT has no noticable 'processing delay' that makes the sound
obviously out-of-synch. Alas Plasma/LCD/etc do tend to do this, so you end
up needing a delay to resynch the sound and vision. The logical place for
this is in the display since that should get it right by default. But then
see my about comment about TV makers!...

Slainte,

Jim
