Samsung forum: No audio out for digital channels on LED TV?

mauiguru,

I agree, this doesn't sound correct. How do you have the television hooked up to the cable, and how do you have the audio set up? Optical or RCA?

Are you using just external speakers or does the RCA lead to an amplifier first?

Keep me posted.

After more reading, I suspect I know what might be happening. When watching DTV channels the optical audio output is 5.1CH. This is the only reference I've found to there being an audio difference between analog and DTV channels.

I'm guessing that 5.1CH requires a compatible decoder and can't be used by just anything with a TOSLINK optical input and that my stereo speakers don't support 5.1CH since they are not a surround system.

I expected anything not capable of playing 5.1CH would just play as normal stereo, but if that is not the case then it fits the symptoms.

I expected to at least hear basic stereo if my speakers don't have 5.1CH support, is this not the case? Must I have 5.1CH digital audio equipment to hear the optical output at all?

Or is there any way to disable the 5.1CH output for those of us who don't use surround sound?

Perhaps I'm completely wrong and the 5.1CH output isn't even related to these symptoms?

FYI, I just found the analog audio output on the TV, it's not labeled and I hadn't noticed it between the USB connectors. I would have found all this info much more quickly if a manual was included with this $3000 TV. (I also wonder if that's even legal since it's the only place I found the Gnu Public License language.) I would really prefer to have a paper manual.

MTS is set to Stereo. It's also grayed out and not changeable.

Analog audio would be a giant backward step for several reasons, cable length being a significant factor as well as not having any available analog inputs on my speakers.

The frustrating thing is that absolutely _all_ my issues would be solved if this TV had variable digital stereo audio out. Unfortunately it looks like there is no way to get digital audio from the TV to the speakers without spending hundreds of dollars on an A/V receiver I shouldn't need. I'll keep looking for a solution, but it's looking pretty grim at this point. (sigh)

On my unit the analog audio output is a mini headphone jack between the USB ports. I noticed in some pictures it is labeled on some units, but not on mine, and being black it's not very visible so I hadn't even noticed it.

Perhaps the TV is so inexpensive because they saved printing costs by including a paper manual. Oh wait... heh.

I seem to have the same problem as everyone else here. I just had a look through the menus and couldn't seem to find any MTS settings. I just bought the latest Samsung LCD series 8 tv and can't get audio on digital channels. Where are the MTS settings??

I just purchased...

LG LED TV Model 47LW6500
http://www.lg.com/us/tv-audio-video/televisions/LG-led-tv-47LW6500.jsp
and
Onkyo TX-8050 Network Stereo
Receiver
http://www.onkyousa.com/model.cfm?m=TX-8050&class=Receiver&p=i

The Onkyo Data Sheet...

http://63.148.251.135/redirect.cfm?type=sell_sheets&file=TX-8050_Info_Sheet.pdf
says "multichannel audio" is not supported and
that sounds rational because this is a Stereo Receiver (and not a Home Theater Surround Sound System).

The LG TV and two built in speakers and no doubt, that is stereo and analog.
The LG TV does not have any RCA jacks for audio out.
However, using a magnifying glass, I was able to read a label on the rear panel
that says " H/P " followed by a Headphones icon.
Below that label is Mini Stereo Headphone Jack.

I purchased a Mini Stereo Headphone Plug to 2 RCA Jack Adapter /
Patch Cord.
Then I connected the patch cord from the LED TV's headphone jack to the Stereo Receiver's "PHONO IN".

BENEFITS: It sounds absolutely excellent.

DRAWBACKS: This is a cludgy workaround (and not a technically correct solution).
1) The specifications for the LED TV's Headphone
Jack and the Stereo Receiver's Phonograph-In Jack are likely to be very different where
the LED TV's Headphone Jack could probably produce voltages larger than the PHONO IN's
maximum voltage. So, the LED TVs volume control should be
used at lower levels only.
Then on the Stereo Receiver, just set the
volume up to around 30 or 40% or so.
2) Now my turntable's RCA plugs are disconnected
from the Stereo Receiver
NOTE: The Onkyo TX-8050's other RCA jacks { CD, TV/TAPE, GAME CBL/SAT, VCR,DVR, BD/DVD } for audio inputs wouldn't work for me. Because the users manual does not characterize / specify the nature of these jacks in detail, I will have to contact Onkyo for support.

IN SEARCH OF A TECHNICALLY CORRECT SOLUTION:
With regards to a technically correct solution, I don't have a thorough understanding of the specifications nor quality issues ( performance, cost, etc ) faced by LED TV manufacturers nor
Stereo Receiver manufacturers.

However, with regard to LED TVs / manufacturers,
my observation as an end user is that LED TV's have
2 Stereo Speakers and a Headphone Jack.
1) Would a reasonable expectation / requirement include
adding a pre-amp type of audio output on RCA Jacks?
2) Would a reasonable expectation / requirement include
adding the ability for users of analog stereo equipment to configure the Fiber Optic audio output to be analog
format only (instead of the default digital home theater
surround 5.1 or whatever it is)?

With regard to modern day stereo receiver manufacturers,
1) would a reasonable expectation / requirement include
adding a miscilaneous / auxiliary audio input?
NOTE: On my 1970s vintage Onkyo Receiver, I always used " TAPE IN " and that worked.
I'll have to ask Onkyo old stereo works and new stereo fails.
Stay tuned.

i had this problem until i change my digital output settings from dolby to pcm... then it worked ?
go into sound .> spdif output > change from dolby to pcm ... i had this problem with all my tv's ... dolby never seems to work...
