Hello,

I have been having an interesting issue with my PS3 and my Surround sound system. I have the PS3 connected to my TV (Panasonic 42" plasma" Viera g10 series) via HDMI and the PS3 to my surround (Panasonic SC-PT760) using Optical. When I play games the surround works, and when I play dvds. However, when I play a Blu-ray movie, The English audio (Dolby Digital 5.1) won't play through the surround and I have to change audio to HDMI to play through my TV Speakers. When I play it in French, Spanish, etc., The movie plays in surround. I have my PS3 video set up as Bitstream. I don't know what else to check. Thanks!

This is because the high bitrate audio used on Blue Ray (Dolby True HD, DTS HD master audio and Uncompressed PCM) is too high for the optical output. DVDs and games use Dolby digital or DTS which is low enough bandwidth to be sent via optical. The new higher bandwidth audio codecs require the audio to be sent via HDMI to your receiver. Generally they have HDMI inputs and at least one HDMI output which you can send to your TV or projector.
You get the foreign language audio because they are usually stored on the disk as the lower bitrate formats.

That will make no difference I run my PS3 thru optical at the moment too if you try and pass say for example tru hd the ps3 will downmix to dolby digital at 640 and Dts master as vanilla dts at 1.5.

To the original poster, I will check my settings this evening and get back to you.

Actually have you got your audio out settings on optical too?

I think the issue you're having is because panasonic all in ones don't support dts over optical.

For dvd's and blu rays with dolby audio, you should get dd 5.1ch - set your ps3 to output bitstream over optical in video settings.

For dvd's and blu rays with dts audio, you should set your ps3 to output linear pcm over optical. It'll mean you only get stereo, but you can use prologic for a surround effect.

Playing blu rays through optical shouldn't normally be a problem as all blu rays should have a standard dd / dts 5.1ch track for backwards compatibility.

Quantum of Solace is DTS only, on BD, and personally for one, i have always thought DTS soundtracks sounded far better than the Dolby ones.
