Sound outputs on flat screen tv's

In most cases the sound out of the SCART/phono is not affected by the
volume/tone controls - you are assumed to do that with whatever you have the
TV connected to - at least it has no effect on any of my TVs.

We're talking here about sound output from the dedicated phono audio outputs
on modern LCD TVs. I suspect you're thinking of CRT sets, especially since you
appear to view SCART output and dedicated phono outputs as being one and the
same thing.

The SCART on a HD-ready set will work as you describe, but will never carry
audio from HD sources.


By your own admission the sound comes straight off the DAC which is raw,
'uncorrected' audio.

The sound on the dedicated phono audio outputs (if fitted) comes from the TV's
internal DAC. (Even analogue sources get digitized within the LCD TV, so that
a short delay can be added to compensate for image processing time.)
On most sets, the volume and tone control also takes place within the digital
domain - hence it also affects the sound on this output.

Then get yourself a decent set. Tone controls operating on a line output
is a nonsense.

It certainly does. My guess is that most sit to far away from large
TVs to use ordinary headphones.

Don't give up the day job.

More credible explanation than yours.

I'm hard of hearing and have a inductive loop system fitted in my room
working of the loud speaker socket (3.5mm) of an old CRT TV. which is still
active when the internal speakers are in the mute condition. I need this
facility because my wife likes to read while I watch TV.

I've been looking to replace the TV with a Samsung 40 inch flat screen LCD
model. But I find that this model has no L.S. socket output. The audio
output is by a Phono socket. (I can change the plug to phono on problem).
My question is when the internal speakers are muted are the audio phono
sockets still giving output so my inductive loop system (Amplifier) will
still work.

I've asked the supplier but he says he doe's not know, and has no facility
to try it .

Would someone with knowledge please advise me as to the best conclusion to
this problem.

Thanks in advance for any information

It's a fact, except on Planet Plowman obviously...

Duh... except that small screen LCD sets typically don't have headphone
sockets either.

Duh yeh, everythin wot us Bill sez is right, but everythin wot every1
else sez iz just them tryin ter look gud wiv there ego like, unless
there praysin us Bill that is.

Well, normally, phono sockets are at lin e level and not controlled by the
volume, though of course might be by mute, i imagine though if you get used
to putting volume to zero it will work provided the loop system can take a
line level input. It would need to be from both channels of course so a
special lead might be needed.

If my memory serves, the set he has has a speaker/phones socket and this may
well be stereo if its the stereo version. The mute condition is merely by
plugging in I thought. Many sets do have headphone sockets these days so it
may well be possible to do exactly the same with the stereo to monno caveat
mentioned.

If you buy the telly and try the stereo phono output, you should find that
the sound level from that output is not affected by the volume setting.
But if it is, buy a scart to phono (or 3.5 socket) and plug into AV 2 on
the telly. There might be a menu setting that determines what sound goes
out to AV2 -- sound from the tv set's tuner or from AV1. There's a bit of
an issue at the moment with AV2 outputs from HDMI inputs -- can anyone
clarify? Modern tvs generally have stereo outputs, and if a 3.5 jack is
used it will be three pole one, which might need an adaptor for your old
mono 3.5 jack.

This isn't really my subject, so I hope others with clarify/correct.
