Digital Audio Output on TV

I have my digital audio output of my Sharp TV connected to my Pioneer Reviever but I get no audio (Digital Audio Oput)when the input of the TV is in HDMI (Input 4). This is my PS3. I get an audio signal when the TV is on regular cable.

Any suggestions?

Re: Digital Audio Output on TV

When using HDMI as the source, the Dolby Digital data will NOT be passed through. If you switch your cable box or satelitte receiver to PCM audio it will pass that through.

Jacks on back of tv set which are audio out

On a typical Aquos the audio out is available in three methods. On the attached image the section identified "OUTPUT"t has starting on the left is a headset connection. The next is an optical connection, This optical is by far the best choice due to having a digital connection to your amplifier. The connection to the right of the label output are two RCA connections one red and the other white. These two connections (left and right channel) provide a superior connection over the headsets located on the far left but not as good as the optical.

Other RCA connections on the back of the TV marked Red and White are for audio input to the TV. There maybe some setup in the TV menu required to direct the audio output to the back panel connections.

Hi I've just brought the sharp HTS-L75 and I don't know how to active it to my tv menu model LC-42LE771K?

There are several different options. But you will probably want to use the HDMI (w/ ARC) connection from the TV to the subwoofer. (HDMI cable) The soundbar attaches to the sub with a standard speaker cable. You will need to configure the 'Sound Mode' and 'Digital Out' settings in the TVs Sound Menu to output the audio on the digital output / HDMI connection.

I have a Sharp Aquos LC-60LE640X TV and I am trying to connect a Samsung HW-H751 Soundbar to it. I have hooked up the optical cable, adaptor and sub woofer, I have tested the Bluetooth function throug

If you are connecting the soundbar to your TV with the digital audio cable, make sure to select "D IN" using the source button on the soundbar. Bluetooth (BT) is a separate source from another device. (phone, etc.) The TV will need to be set to use the digital audio output and probably PCM format. (?) The subwoofer is preconfigured at the factory to mate up with your soundbar. (See below instructions - your soundbar includes the amplifier:)

Digital audio output setting:
After connecting an amplifier with digital audio input and
external speakers as shown, you should set an audio
output format compatible with the programme you are
watching or the device connected.
Go to "HOME" > "TV Menu" > "Setup" > "Option" >
"Terminal setting" > "Digital audio output" > select
"PCM" or "Bitstream".
• When set to "Bitstream", Dolby Digital is output when the Dolby
Digital or Dolby Digital Plus audio formats are received. When
set to "PCM", PCM is output no matter what audio formats are
• When set to "Bitstream", HE-AAC audio formats can be output
as Dolby Digital.

I just purchased a Coby TV Model number TFTV 3255. I am very happy with the set. However it has only ONE audio output. The manual, on page 7, "coaxial output" ,an optical audio cable is required....

If it is a single output and looks like an RCA type, then I would say that the cable you would need is a digital coaxial cable. The optical input/output will have a different shape and is not as big of an opening as a digital coaxial input/output.

Unable to access digital audio output options

Well you also need to have a digital feed to the television. example: When I run my optical cable from my dvd player to my television directly. I went in to my menu options on my source and enabled this. If you are wanting to run this feed to your a/v amp? You may want to run the original feed from your dvd player to your amplifier directly, you will get a sound quality that is far superior to what you seem to be doing here.

No Digital Audio From Sharp LC-37D64U

Try changing the the Audio Setup in the Digital Setup Menu.
If you have your manual, go to pg 11 and pg 28 for Digital Audio Output. If you need a copy of your manual, here's the link.,1083,127,00.html
Page 11 has info on the problem and page 28 to solve it.
If that doesn't work, I would try downloading the latest software to fix is problem. Page 28,2310,,00.html?model_num=LC-37D64U&s_func_disp_id=27&x=42&y=11
