Optical sound problem

Hi, I have my PS3 connected via HDMI to my screen and via optical to my Sansui RZ4900AV. The problem is I get a high pitched noise to my centre speaker when the PS3 is on. It is not very loud but it is irritating. Any help will be appreciated. Thanks

Re: Optical sound problem

I have the same problem with the RZ-4900AV, it manifests itself when any video application runs through either the optical or coaxial input. in my case it's definitely not the optical cable itself, which works fine on another receiver. optical or coaxial input of audio CD's is fine, but a DVD video on the same DVD player gives the high pitched whine. the same with the PS2 on the optical input, audio CD in the PS2 no problem, PS2 game or DVD video gives the whine... i think, unfortunately, it's a crap receiver... and i solved the problem by buying a RZ-6900AV, which works perfectly in exactly the same environment.

PS3 surround sound

You will need the optical cable. My receiver only passes video through the hdmi. So I hooked up the HDMI cable to the tv, and the optical cable to the receiver. Once that is done you have to go to the audio settings for the PS3 and chose audio through the optical.

Adjust the system's audio output settings. These settings are mainly used when the system is connected to audio devices that support digital audio output, such as AV amplifiers (receivers) for home entertainment systems.
Confirm the formats supported by your audio device.
Settings vary depending on supported formats. For details, refer to the instructions supplied with the audio device.
Select in_soundset.gif (Sound Settings) under in_setting.gif (Settings) in the home menu.
Select [Audio Output Settings].
Select the input connector on the audio device. Channel numbers and audio formats that are supported vary depending on the connector in use.

Select audio output formats.
Select all output formats that are supported by the audio device in use. If [Audio Input Connector / SCART / AV MULTI] is selected in step 4, the screen for selecting audio output formats will not be displayed. If [HDMI] is selected, you can also select to automatically set the audio output format. (In this case, the HDMI device must be turned on.)

Check your settings.
You can go back to the previous screen and revise the settings by pressing the in_left_key.gif button.
soundoutput002.jpg 7.
Save your settings.
The audio output settings are saved on the system.
  • [Linear PCM 2 Ch.] audio is set to be output from all output connectors by default. If you change the audio output settings, audio will be output only from the connectors that were set.
  • If you change the audio output settings, the system will no longer be able to output audio from multiple output connectors at the same time. For example, if your system is connected to a TV via an HDMI cable and to an audio device via a digital optical cable and you switch to [Digital Out (Optical)] under [Audio Output Settings], audio will no longer be output from the TV. To output audio from the TV, switch the setting to [HDMI], or select in_setting.gif (Settings) > in_soundset.gif (Sound Settings) > [Audio Multi-Output] and set the option to [On].
  • If you select [Linear PCM 2 Ch. 88.2 kHz] or [Linear PCM 2 Ch. 176.4 kHz] in step 5, sound may be intermittent or may not be emitted from some audio devices.
  • When using an HDMI cable, only [Linear PCM 2 Ch.] audio will be output from PlayStation®2 and PlayStation® format software. To output Dolby Digital or DTS audio, you must connect the PS3™ system and the audio device using a digital optical cable and switch to [Digital Out (Optical)] under [Audio Output Settings].
  • If a device that is not compatible with the HDCP (High-bandwidth Digital Content Protection) standard is connected to the system using an HDMI cable, video and/or audio cannot be output from the system.

Simultaneous Optical & HDMI Audio on PS3

I'm almost positive it cannot stream the sound through two outputs by design. However if your TV has a digital optical output you can run it to the TV via HDMI and from the TV to the receiver go with the optical. It shouldn't bother the quality at all being HDMI is also a digital interface, you're just passing it through your TV.

No sound from ps3 to home cinema via an optical cable

If you have not run the set up you will need to, however I'm guessing you did because you would have had to make some changes to the settings to get the image to come up on the screen but without being physically at your location I can just guess.

In order to view your PS3 in full 1080p you need the HDMI cable which you already have. If you have not gone into your video settings then you are not viewing via the HDMI cable and you will need to to get things working right.
In order to view via the HDMI cable you would have had to had both the standard PS3 interface cable that comes in the box (the one that goes from the PS3 to your tv with the composite video (yellow) and the left and right audio (red and white) and the HDMI cable pluged into your PS3 and your tv at the same time. then you turn on the PS3 making sure your TV was set to whatever imput the composite and left/right audio is pluged into (typically VIDEO 1,2,3 ect.) and enter the menu, go to the settings and then down to your display settings and change it to HDMI, the image should then leave the screen (because it switched to HDMI) you will need to have your TV remote handy for this because you will need to switch sources on your tv to HDMI 1,2,3 ect, which ever one you have it pluged into. When you have switched to the right HDMI imput there should be an on the screen that is counting down and asking you if you want to accept the changes. Select yes and Move on through the settings selecting the maximum resolution your tv is capeable of
720, 1080i, 1080p) which can be found on the box the tv came in or somewhere on the tv or manual. While running this settings change it should ask you the audio source you are using make sure you select Digital Optical and that it is pluged in to you PS3 and your reciever. Once this is all done you can remeove the standard PS3 hook up that came with the box and put it away you wont need it any more, unless you move the PS3 around and the tv you move it to does not have HDMI in which case you will have to change the settings before you move it back to the standard cable or you will not be able to see it displayed on the tv sceen you move to and it will be impossible to run the settings.

If you have already done that and just want to verify that your source for audio originating from the PS3 is digital optical you can check that in the same settings menu under audio settings. Then make sure the reciver is on and set to whatever imput you have the cable pluged into and you should be good to go.

If all that I have described has been done already then the audio cable could be bad or the problem lies internaly with the PS3 or the reciever.
Good Luck hope this helps

I am pretty sure you need to have an Optical cable running from Your PS3 to your sound system...if you have one...

So basically you will have a HDMI cable running from your PS3 into your TV, another HDMI cable running from your TV into your sound system, then an optical cable running from the PS3 to the Sound system. I sadly own a HDDVD sound system but the optical cable tells it to accept the Blu Ray content.....

Ps3 using digital optical and hdmi cables together

There is a conflict in the fact that HDMI gives you the digital surround sound without the need for the optical lead and when you allocate the optical for the sound thats when the conflict starts, you can only use one or the other.
