Check your settings on the unit and also the source of the sound. Sometimes it can get switched to PCM by mistake, or can be interfered with by something like a setting for down-mixing, which should be switched off.

If your tv and reciever have optical audio (square-ish hole with a red light), that would be the easiest way. Just get an optical audio cable and plug it into the optical out on the tv and into the optical in on the Sony.

Unit will not power up, when plugged in to AC the mute -20 dB is lamp is illuminated. Is there a reset feature?


Sony consumer grade electronics are notorious for electronic component failure due to the low quality grade of their components. It's likely that the whole circuit is not receiving power. If you are handy you can search the internet for a service manual and follow the flow chart to troubleshoot the defective circuit.

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.

Rear speakers do not work


Make sure of what audio mode you've set your receiver to, as well as what the source audio signal contains.

Some modes, such as Dolby Digital/Pro Logic will adopt the input format, and subsequently use only the front left and right speakers if there are no LFE/Center/Surround channels present. Setting the mode to Pro Logic II or IIx, on the other hand, will force a signal to be spread out to the various extra channels.

Using the Automatic Field Detect mode will usually provide the most appropriate solution for the input signal, otherwise.


Also note that if your audio source is from a PC and you are playing games, some games will, when you are using the digital output of many sound cards (most notably the Sound Blaster Live! and Audigy 1-2 and Audigy SE model cards) output only stereo as their signal, but still in a digital format. Your receiver will pick this up as a stereo specific signal and avoid using the subwoofer, center and surround channels.

Unfortunately, for those cards, there is no work-around beyond using analogue output or getting a more recent, better compatability sound card, as it is a limitation between the drivers, the card and the game in question, rather than your receiver that has the issue.

If the above doesn't help alleviate your issue and/or you could clarify on what your source audio is and whether you encounter this issue with all source-types or not, please post a follow up response.

I'm going to surround sound mode, and my rear speakers are not working. I do a tone test, and they def work, but I can't get them working right?


Since you seem to be having problems with 'simulated' surround, how does ACTUAL surround material behave?

Have you tried AFD with certifiable multichannel source material to verify the surround speakers receive programmed sound??

Do the Dolby Digital or Pro Logic indicators light?

What about the other modes?

How can i get the dts sound field to work. Shouldn't it automatically switch to that sound field. I have a samsung bluray dvd that hooked up to it.  The dolby pro logic and pro logic 2 indicator...


If you are playing media that has both dolby digital audio and dts audio, your player and your receiver will decode the first audio codec listed first by default unless you select it otherwise yourself. If your remote or receiver has an A.F.D. (auto format decode) button, press it until your display shows that the sound source is dolby digital or DTS, whichever sound mode it was you wanted when you started your DVD.

Surround sound for Blu Ray on older Sony receiver


Hello, it sounds to me like the receiver doesn't support the sound format being sent from the blu-ray player. This is because the blu-ray disc would have HD encoded sound such as DTS HD Master Audio or Dolby True HD. Most receivers have not been fitted with these sound formats untill quite recently. The reason for the menu sound playing correctly would be for the PCM (Pulse-code Modulation) which sends simple two channel digital sound supported by all digital receivers. It may be possible to use Dolby Pro Logic or similar formats to give a surround feel, but the only way to get true surround sound in this way would be decode the sound externally and input it through several phono cables into the multichannel input, however blu-ray sound comes in 7.1 so the receiver would need to be able to accept this to get the full effect. If it is possible, see if the blu-ray player will allow downsampling to a surround sound format that your receiver can accept such as Dolby Digital or DTS. Hope this helps.

Only Direct sound works good, and only two speakers


Some sound fields have reverberant effects that need adjusting so the levels become audible, such as in "stadium" mode. While playing one of these sound fields, navigate through the speaker setup menu and make adjustments to the "effects" percentage, and levels. Be aware however, that only in 4 channel stereo mode will your surround speakers produce sound 100% of the time. Also, in any form of Dolby Pro Logic mode you will hear more sound from the surround speakers originating from stereo source material than from monoaural material...example, a television station broadcast in stereo versus mono.
