ps3 optical settings advice please

[stow123]

Im waiting for an optical cable will then be hooking up my ps3 to my reciever its a pretty old reciever although it does support dts 5.1 and dolby 5.1 and pro logic II .I know i pick dolby digital 5.1 and dts thats obvious but im not sure what pcm settings to pick theres 2ch 88.2kHz and 176.4Khz how do i know if theyre ok to pick so i dont damage my speakers.Also whats AAC as thats on the list too and whats it mean in the manual when it says if bitstream is selected for optical some of the sound might not be played.

When it says that some of the sound wont be played when bitstreaming over optical, means that High-def audio codecs will be downplayed to their core component tracks so that the information can be passed through the cable. An optical cable does not have the bandwith to bitstream high def audio codecs or more than 2.1 PCM. If you want a surround sound experience and you are using an optical cable, you must set it up to bitstream the core DTS or Dolby Digital tracks to the receiver.

Set it to 88.2kHz. At least that's how it works with my setup. If you turn on 176.4kHz, it most likely won't deliver any sound at all since TOSLINK doesn't support it.

Also whats AAC as thats on the list too and

AAC is the audio encoding format used by Apple, like the ones used on iTunes and Quicktime. Since you said your receiver is old, do not check this box. Let the PS3 decode AAC to PCM via optical.

whats it mean in the manual when it says if bitstream is selected for optical some of the sound might not be played.

Most probably about 5.1 LPCM soundtrack on BD. If you want true 5.1 on your setup, set it to bitstream and check the Dolby Digital and DTS box.

ok I have a question to go kind of along with the first post...

I have my Audio Outputs on Linear PCM (optical) on my PS3 (80GB). Now my issue is that I was watching Gods and Generals, 101 Dalmations (Platinum) & Indiana Jones over the weekend and certain random parts of the voice audio not complete audio (music & sound effects) where not playing???

Any reason why this is? I am running an Onkyo receiver not sure what model, but its newer.

Is my issue just a matter of changing my Audio Output Options to Bitstream?

Any help would be greatly appreciated

Thanks

I assume these are DVDs. The reason is these tracks are probably in 5.1 and are downmixed for 2.0 PCM delivery via optical. Downmixing will not give you the full 5.1 effect so some effects or vocals or music may not be heard prominently.

set it to auto and let the ps3 decide whats compatible.

[lgans316]

Resident Evil : Extinction (Dolby True HD 16-bit via TOSLINK) - Showing as DD Multi-Channel at 448 Kbps

300 (Dolby True HD 16-bit via TOSLINK) - Showing as DD Multi-Channel at 640 Kbps

PS3 owners looking to take advantage of the audio bit rate via TOSLINK should embrace DTS / DTS-HD MA over the other audio formats.

Contradicts what is mentioned in the below chart.

Read the thread on Home Theater Audio CODECs. It will help you understand the differences between the CODECs as well as the connections needed.

As far as damage to your speakers are concerned, you don't have to worry. If you turn the volume up and your speakers cannot handle the signal, you will either hear distorations or you will blow your speakers. Before that happens, you will probably damage your hearing permanently.
