Hello there. I am encountering a very bizarre issue that I would like addressed A.S.A.P.



my setup is as follows:



Playstation 3 connected to my Samsung LN46A650 HDTV via HDMI

Panasonic SC-PT960 5.1 Home Theatre System connected to back of my television via optical cable.



Now... I play my PS3's audio through these speakers while playing games and Blu-Rays, but I cannot achieve perfectly clean audio with the Dolby Digital 5.1 box checked in the audio options. Instead, I encounter a strange and hard-to-explain "ZZZT" noise at very brief moments throughout the course of whatever media is being played.



Also, the audio drops briefly and well, just... all sorts of strange behavior is displayed when playing audio with the DD 5.1 box checked.



However, when I uncheck the box, I am reduced to 2.1-channel audio (obviously) within games and movies, but the odd sound effects have completely vanished.



What could possibly be the source of this annoyance? Could my optical cable somehow be faulty? perhaps the speakers don't agree with my setup in some way I'm totally unaware of?! Also... this is a home theatre in a box, so my receiver is a bulky dvd-player instead of a dedicated receiver... perhaps I should try purchasing a new receiver?



Please... if ANYONE has any bit of insight as to what could be causing this I would be endlessly appreciative.



Thanks!

The first thing that comes to mind is that the TV does not send out a 5.1 Dolby Signal via optical. It would only send out a 2.1 and the receiver/dvd player would decode it to Dolby Pro Logic giving you simulated surround sound. You will need to hook up the optical cable directly from the PS3 to your receiver/dvd player. That will allow you to get the true Dolby 5.1 you are looking for.

I do receive true Dolby Digital 5.1 with my current configuration, except for the sound effects. When I try connecting the optical cable from the PS3 straight into the back of my receiver, I still encounter the sound glitches! So I'm seriously out of ideas..

Why don't you try using the rear speakers as your front speakers just to test that its not the speaker itself. Is the system brand new or have you used this with another TV before. If its new I would think that theres a problem with the actual receiver/dvd unit sending the signal out to the rear speakers.
