Question about Sony Playstation 3 (PS3) Console

1 Answer

Playstation 3 I have a playstation 3 80GB. I can not get full digital sound from the units optical output when playing DVD's or Blue Ray disks. Have switched, on the menu, to bitstream output, but the unit only puts out PCM sound (not 5.1 or better) Any thoughts?

Re: Playstation 3

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.

Won't load blue ray game

The blue-ray inside your ps3 could be dead. I suggest try playing a DVD-Movie. If this doesn't work than it is dead. To replace it you would either need to call Sony or open the ps3 (This will void your warranty), locate the blue-ray, and find out the model and look in ebay to replace it.

Different Audio output between DVD and Blu-Ray DVD


The issue is that not all videos use DTS. Look at the videos that you are trying to play do they support DTS if so make sure that you are selecting the DTS track in the audio setup.

In regards to your receiver if it does not support Dolby Digital then you might want to look at upgrading to a receiver that supports Dolby Digital and DTS if you want true surround on all your videos.

Let me know if you have any more problems or questions

Sony palystation 3 80g only plays DVDs and sony playstation 2 gam

You need to replace the blu-ray laser. It's a VERY common problem. It's due to a factory defect with the laser.

Most 80GB models use laser model KES-400A or KES-400AAA.

You can either contact Sony for repair 1-800-345-SONY.

They charge $150 or you can go the DIY route for under $100.

PS3 80g only plays DVDs and PS2 games .... help

The reason why DVDS still work and the blu-rays don't is because it's a three part laser. dvd / cd / blu-ray.

The blu-ray portion almost always goes out first.

Blu ray movies do not play

Have you checked your video output for the bluray to make sure it is set properly? You should be able to set it to automatic so it will be able to set the signal at the proper level. It also wouldn't hurt to try a lens cleaner which is for the Bluray and ps3 system. (approx $25 at BestBuy)
