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".
NOTE
• 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
received.
• When set to "Bitstream", HE-AAC audio formats can be output
as Dolby Digital.

TROUBLE SHOOTING TIPS


NO POWER
Check the fuse F01. If the fuse is open change the fuse after confirming there is no other faulty component.
If fuse is OK the check C10 voltage is normal or not. If its not normal then change BD01.
If the voltage on C10 is normal the check the SMPS switching ICs IC01 and IC02. If found faulty change IC01 and IC02.
NO DIGITAL AUDIO OUT
Check the current digital audio stetting is its in PCM or Bitstream . IF it's in PCM then change it to Bitstream.
If ther is no diagital audio out even after it to bitstream, check the AV receiver settings. If everything is ok there too then check the AUDIO DATA at AIC Pin 4 (for BD)or AIC3pin 13 (forDVD) using CRO. If there is no audio data the change the main PCB.
If the AUDIO DATA id ok then check DIGITAL AUDIO DATA at pin7 of AIC3 if there is no audio data then change AIC3. If its OK, Check 5V at AIC2 pin 14. If the 5V is missing check the power supply. If 5v is ok the change the main PCB.

Yamaha RX-V595 Receiver will play Dolby Digital 3/2.1 audio Blu-Ray disc with player set to bitstream but will not play DTS-HD 3/2.1 unless output is set to PCM. Is this an issue with the Yamaha Recei


The optical connection (SPDIF) doesn't have enough bandwidth to transfer DTS-HD audio. To use DTS-HD, you must connect the blue-ray player and receiver via HDMI cable.

Each DTS-HD audio track on blue-ray includes also "normal" DTS audio, which is probably used when you select PCM. Player decodes it and sends decoded (non-HD) audio via optical cable to receiver.

Digital output through DAC static


Set the digital output in the TV menu to PCM instead of Dolby Digital. Your DAC probably can't handle DD.

Why can I not change the setting from pcm to dolby digital on my tv


You don't. You change the signal at the source device end, not the TV.

If you have connected a Blu-ray player or a games console, then set the device audio option to Bitstream. This will send a data stream to the TV that it will decode either as Dolby or DTS depending on the source signal format.

Dolby Digital is only an option for an external AV source connected via HDMI. That's the only way to get a Bitstream signal in to the TV. The TV's internal tuner is only capable of PCM audio. It's a DVB-T tuner (standard definition) rather than the DVB-T2 tuner needed for HD. Even then, only the HD channels are encoded in DD.

Iff your BD player or console is decoding to stereo PCM, then it's doing the same job as the TV. There's a small advantage with one of the audio processing modes in how it limits the dynamic range, but other than that PCM and DD will sound identical. This is especially the case with any TV that has no optical audio out, as in this case. The TV can't pass a DD signal out to an external audio system. So all sound is played via the internal speakers or headphone jack. It'll all sound the same, PCM or DD.

How to get audio on Phillips blu ray


If playing direct in to the TV, make sure the player's audio menu is set to "mixdown to PCM" or just PCM rather than Bitstream. The reason is that most Blu-rays contain audio in DTS format. But very few TVs can handle the raw Bitstreams DTS data feed. Let the player do the conversion to an audio format that the TV understands. PCM is pretty universal. It'll be just stereo, but that's okay because your TV probably can't do much more than that anyway.

There is no single answer. It would depend on the nature of your source digital audio (duh). Try them all. I use many non-standard digital modes on music, for example, and they all yield sonic differences with varying degrees of improvement or novelty.

Hello what is the best setting for ps3 slim when played through onkyo 608 pcm or bitstream at the moment it is saying multichanel on the amp if i change it to bitstream it says on the screen some audio...


Bitstream will pass the HD digital audio directly on to the receiver, in either DTS or Dolby format. This allows your receiver to decode these formats. The Onkyo TX-SR608 is capable of decoding all the new HD audio formats, and has quality Burr-Brown digital-analogue converters so it would be a shame not to use bitstream in my opinion.
Electing to output the sound as PCM will utilize the PS3's internal digital audio decoding, and I believe output a two channel analogue signal... which your receiver will then reprocess into simulated surround sound... not ideal really.

5.1 sound system (blue light) does not come on. sound comes and goes, sometimes quiet, sometimes lound. dolby does not seem to work .


what is your source? (DVD, Cable, Blueray, etc.) My guess is that you have your source set to output PCM instead of bitstream. Check this in the menu of your output source. If it is PCM, it will only output 2 channels unless you are using an HDMI cable. If you are using an HDMI cable, the sound should be the same, but it is sent directly to the speakers using your receiver as a pass-thru. Your receiver will not detect it as dolby or dts as it is not actually doing any processing. When you check the menu, bitstream may also be listed as "digital". Hope this works for you.
