I am not sure if this is the correct NG but here goes.
I have a vintage Techics Hi-fi system that has stood idle since the
arrival of widescreen TV, mainly because it is on the opposite side of
the room.

The TV is connected to a computer that runs Mythtv an serves as an HTPC.
It has a cheap 3-speaker pc system that is an improvement on the TV's
speaker but is in no way "good".

We plan to move and I wondered if the hi-fi system could be geared to the
TV and /or computer. I am uncertain as to the best way to connect up.

The question is, what audio outputs the TV has (if any). Some "modern"
TVs don't have an audio output, or only optical, but you can get HDMI
adapters to extract the audio from one of the TV sockets I think.

My Sony has a 3.5mm jack socket, and it can be configured (through the
menus) to act as a line output rather than for a headphone, but the
headphone output should work all right, as the mismatch in level
compensates for the mismatch in impedance.

Thanks for this but I think I really need to replace the 2:1 computer
sound system with the hi-fi system.

It looks like you have clarified this. The grren socket aotputs analog
sound and that can go straight into the amplifier.

Thank you.

yes. I am driving my hifi from a 'headphone' socket. that way the volume
control on the TV works.

I think on that TV the only other alternative is optical, and that needs
a converter.

When I lived in a much smaller house with my settee only about 4 feet from
the (14") TV, I had my hi-fi unit next to the TV, and took a line-out feed
from the VCR to the hi-fi, and listened using wired headphones. This was
because the sound circuit and speaker in the TV were fairly poor - and
anyway they were mono because the TV predated NICAM. I very rarely, if ever,
had the volume turned up on the TV.

One thing that was interesting was to play the sound of ITV
(Southern/Meridian) through the TV and sound from ITV (Thames/LWT) through
the hi-fi and headphones - I could receive from both regions - and there was
a time lag that was just perceivable, especially on the "bongs" of News at
Ten. Nowadays, with fully digital feed to the transmitters and from the
transmitters to the TV, I imagine that the time difference might be *much*
greater depending on buffering.

Yup in theory fine, as long as the amp has some spare inputs and you can
get a suitable line level signal to feed them. Note that the PC will see
the audio device on the end of the HDMI lead and its own analogue
outputs as separate audio output devices, so you may need to switch
between them if swapping from TV to HiFi audio.

(or take a feed to the amp from the the TV to capture whatever its
"playing". Sometimes this may need to be via a optical to phone
converter since not all modern TVs have analogue audio outputs for some
daft reason, but most have a SPDIF / Toslink out)

Not a problem if you are taking the feed off the TV itself. The delay in
the optical to DAC converter is at most a few us.

and a 20? YO Phillips cassette/radio in the kitchen. If both are on
and tuned to the same BBC FM channel I can hear that they are out
of sync for some reason.

Are you sure one of them isn't on DAB or using a DAB digital tuner of
some sort for FM reception which introduces an interesting delay on
programme content (as well as being highly inefficient).

Most noticeable when the pips are on the hour and you can hear more than
one tuner in different rooms. A classical FM decoder should produce a
radio output with at most a few us timing error.

No audible delay between any FM tuners I've ever heard. But may well be
within the computer, which likely changes the analogue to digital and then
back to analogue for its speakers.

Roberts Play using FM has a bit of an echo with other (frequency
synthesiser type) FM radios.

Motorola smart phone FM radio function has a delay of about 1/3 second.
So there must be some digital processing, even with FM.

(DAB is about 3 seconds behind.)

I don't see why not. I have an optical to phono output on the Samsung bought
from Amazon. The only issue I had was that hdmi lead to pc, put pc sound
into tv after the optical output, so had to pretend it was not hdmi by using
a vga to hdmi box and leaving the sound going via my external sound card
which has phonos too, so one could simply switch it as another source. I
have an annoying pulse though tht goes sheesh every few seconds if the hdmi
is connected on any input, Suspect some polling from the TV even in standby
is actually getting in via an earth loop somewhere, but I guess I will find
it in the end!
I do find however that modern tvs max output via line on these dongles is a
lot lower than the sound effects the TV makes and all other sound inputs so
one obviously does need some kind of level adjustment device I think. Too
many different standards, clearly!

A modern TV may well not have phono outputs. It likely has a headphone
socket, but maybe an ugly way to do it. But it will have an optical sound
output - toslink. You can buy toslink to phono adaptors for not a lot. But
they are mains powered.

If you don't want to run cables between them, pass.

Just don't put the speakers close to the TV. I've a pair of good KEF but
wouldn't want them within a yard of the TV - but don't have room for them
anyway.
I bought a reasonable sound bar and it's agreat improvement. No point in
paying too much as I don't want a sub and going for excellent sound would be

Many reasonably up to date speakers from the late CRT days had shielded
magnets.

Here's one for you to ponder. If stray magnetism affected a TV, what did
it do to other speakers in the same box? I'm surprised Russ Andrews
doesn't have a product to sort this.

There's a whole world of connectors out there, to go from
1/8" to stereo phono. I made up a bunch of adapter cables for my
receiver/mixer, so I could combine all audio device signals
into the one unit.

There are also cables with one type on one end, and the

Keep it simple. Selecting a gazillion switches just to watch TV is not fun.

On the other hand, you probably have multichannel outputs from your
computer sound card.

And I'm now counting that you effectively you have 5.1 speakers.
