Question about Sony STR-DH520 A/V Receiver

Open Question

Dolby digital or PCM sound fluctuation

I get nothing or sound fluctuation when playing films, CDs and console games when trying to listen in any Dolby digital or PCM audio through my av receiver. I have adjusted hdmi settings on the reciever and on the blu ray player, ps3, Xbox 360, and sky box and no luck. Changing them to bitstream and or PCM. Still no luck. The instruction manual has not helped. I hope it's something ive done or not doing and not the reciever. Hope anyone can help.

SOURCE: No Audio

Hi,

Your receiver is the Denon AVR 2105 and not the Sony STR-DG510 5.1 Channels Receiver?

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.

We hooked it up and have no sound


From the Console Settings screen in the System area of the Xbox Dashboard, you can configure the video output of your Xbox 360 console for a widescreen, high-definition TV, determine your audio options, and check your console's serial number and Xbox Dashboard version.
Go to correct section for ... Audio

Change your audio output settings for games from this screen. These audio settings do not affect DVD movie playback. For DVD audio settings, refer to an individual DVD movie's setup screen.

Settings consist of:

  • Analog Output Settings: choose Mono to merge the left and right audio signals so that you can hear all sound through a connection to a monaural TV or monitor; choose Dolby Pro Logic II to listen in normal stereo (no audio surround receiver required) or to listen to Dolby Pro Logic or Dolby Pro Logic II soundtracks from compatible games or other media.

    Dolby Pro Logic consists of four channels of audio: front left/center/right and a monaural surround channel that is mirrored in each of your rear left/right speakers. Dolby Pro Logic II uses digital signal processing to generate 5.0 audio (front left/center/right, rear left/right) from any stereo (left/right) programming, whether from movies, music, or games. Unlike movies and music, however, games are specially encoded with Dolby Pro Logic II decoding in mind.

    To listen in either Dolby Pro Logic or Dolby Pro Logic II surround sound, you must connect your cable's left/right (white/red) RCA connectors to a compatible surround receiver. For more information, see our connection page for the cable you're using:
  • Digital Output Settings: configure this setting only if you'll be using the Toslink optical digital-audio output from a compatible Xbox 360 AV cable (optical digital-audio cable sold separately):


    The default digital-audio setting is Dolby Digital 5.1. If this is your preference, you do not have to make a selection from this screen.

My PS3 has no sound when game starts. It does have sound before game. Also, the Blu-Ray movies skip & dont play.


It sounds like the sound signal type might be incorrect. I'd go into sound settings in the options menu, and when it asks whether you want manual or automatic, choose manual. Tell it to send regular PCM audio instead of the default Dolby settings, and see if this fixes your issues.

Surround sound on ps3


Most digital inputs are assignable, so go to set-up menu on your receiver and make sure the optical port (opt1 , opt2, etc.) is assigned to the input (vcr, aux, etc.) that you want switch to to listen to the PS3. You may also need to go into the PS3 settings menu and turn the optical to output the Dolby Digital signal. You have to do this with most DVD players, too.

In the PS3 menu, open Settings > Video Settings > BD/DVD Audio Output Format (HDMI) or (Optical Digital) depending on which one you are using. Set the type to to Bitstream (Linear PCM does not send the DD stream through).

I can hear cds and see video on my hp dvd 1040i multiformat dvd writer but I can not hear audio to the movie/dvds i have rented.


Sounds like you might have a setting that is incorrect for DVDs in the setup menu.

Grab your DVD player remote and press the SETUP button. Navigate to the audio menu. Make sure Spdif is turned off (unless you're using an optical cable for your sound), that the audio stream is set to PCM (standard for CDs) or RAW, and turn off any Dolby/Digital Dolby/Surround Sound/etc. Now play a disc.

There's also another way if your remote has an AUDIO button. While the DVD is playing, press the AUDIO button and you should see a small windo that pops up that will tell you what the audio is set to. Press the button and wait a couple of seconds between presses to see if the audio starts playing.

I have a panasonic SC-PT850 DVD home cinema system, and although it says it is DTS and Dolby 5.1 compatable but it does not give out any sound at all when i play Blueray films or Playstation 3 games which...


Not so much an answer more a shared problem with a slight insight. On the Panasonic manual page 40 http://www.panasonic.ae/EN/Manuals/SC-PT550%20-%20850W.pdf
It states the following: This unit can decode the surround signals received through cable TV box, digital broadcasting or satellite broadcasts. Refer to your equipment’s operating instructions for details. Only Dolby Digital and PCM can be played with this connection.
So it sounds like the SA-PT850 unit will decode DTS from an internal source ie DVD but not from an external source ie ps3 or WDTV which is a shame because I own a WDTV. The solution for me is to convert the dts to ac3 (Dolby digital) which works great. But not sure if this is an option for you.

First of all, Linear PCM is the best option to choose. PCM (Pulse Code Modulation) is a format for uncompressed raw audio data.

Some 5.1 sets have Dolby ProLogic II for example. The raw PCM output gets spread at your speakers dynamically. Meaning the decoder of your set interprets it the way it thinks is best. For example, if it gets a high frequency tone, it sends it to the center speakers as for human voice has a very high frequency. The center speaker is meant for dialogs.

But when you choose a compressed, encoded format such as Dolby or DTS the channel devidance is already mixed for you for optimal theatre experience.

When you choose DTS or Dolby in the menu of your Blu-ray Disc it will originally output a raw PCM audio stream. The decoder knows how to decode the DTS data out of it when you use the DTS audio track from the movie. The same goes for Dolby. Some movies can output pure PCM, but then most sets use ProLogic II to devide it over the speakers.
It's kinda hard to explain how it works, bottom line is.. there's nothing wrong.

I hope it makes sense to you and your question is answered.

Greetings,

DarkNeogen.
