5.1 audio drop out on Blu-ray Only - Blu-ray Forum

pspoop · 12-10-2006, 11:33 PM

Maybe you guys can help me figure this out.

I got a PS3 over the weekend and I'm connecting with component and optical cables. Everything works great playing games and DVDS, but when I put a Blu Ray disc in, the dolby digital continually breaks up like a scratched CD, but it's only the audio...the picture stays consistent, but the audio gets choppy.

I have a Sony receiver (about 3 years old) that works fine with my DVDs, 360, etc., but the PS3 audio is the only problem. I changed the sound field, and it skipped less...but I can't tell if the problem is the receiver or the PS3. Any thoughts?

It should work normally. What if you don't allow any sound field processing at all? Would that work better?

If you have another optical input that's not used, try that one.

Make sure you have Bitstream selected as audio output. Why? optical does not suport enough bandwith to do PCM wav.

Secondly, with optical your only limited to the standard Dolbly Digital 5.1 and DTS 5.1 tracks.

To get uncompressed you have to use HDMI. Of course, your HT system must suport HDMI. A TV that supports HDMI may have 6ch analog outputs, but your HT system must support 6ch audio which most "HT systems in a BOX" don't.

Normaly on a standard DVD player you can output PCM via coaxil. I don't think PS3 supports coaxil.

Yeah, I've been using Bitstream. The audio starts but it breaks up occasionally-frequently during parts of teh movie.

Is there any way its trying to encode a more powerful format (over optical) than just DD. Because I can't make sense of why only with the PS3 ,and only with Blu Ray playback does it skip.

Deciazulado · 12-11-2006, 11:39 AM

Have you tried your PS3 unit on another receiver to see if its the receiver or the player?

Could be your unit has a defect?

pspoop · 12-11-2006, 03:31 PM

I actually used my neighbor's bose 3-2-1 unit and it didnt experience the problem. So it must be the receiver. Could it be a problem with the speaker wiring, or is it likely just an issue that my receiver has in general.

Deciazulado · 12-11-2006, 04:21 PM

Maybe the sampling frequencies/bitrates are to high or incompatible for your receiver, or there's some clock rate issue between the two. Isn't there a way to adjust various audio settings somewhere (I gave a quick overlook to the manual so i don't remember specifics) I think Brian or someone posted setting variations (Games forum?) Hope you find a solution!

I have been having a Clipping problem from Blu-Ray movies in 5.1

Whenever it gets above a certain level (regardless of volume level) it drops out .
I have tried both the PS3 and the Samsung Blu-Ray player. From the Samsung both Optical and Coaxial. My receiver is a Sony and is fairly new as it has component ins.

Any Ideas?

JTK · 12-11-2006, 04:29 PM

How do the cables look? Connected solidly? In good shape?

shock_terminal · 12-11-2006, 04:32 PM

Tried 2 differant Opticals and a Coaxial, firmly connected. Like I said it happens consistantly at certain spots (high audio level).

dobyblue · 12-11-2006, 04:42 PM

Have you thought about hooking it up losslessly with analog audio outs instead of using coaxial or optical?

shock_terminal · 12-11-2006, 04:47 PM

It works w/ analog (prologic) but I really want DD 5.1 to work.

Deciazulado · 12-11-2006, 05:14 PM

Since you tried two players, it seems your receiver is having some kind of overload/prortection tripping...

shock_terminal · 12-11-2006, 05:29 PM

It would seem that way, when I called Sony they said it was a 1.1 Digital reciver and Blu-Ray was 1.3.
I kinda doubt that because that's not even a spec listed on Recivers and if it were that critical it would be.

theknub · 12-11-2006, 06:01 PM

what receiver is it by the way?

there might be some known problem

Werewolk Killer · 12-11-2006, 06:17 PM

Make sure that the receiver is set to speakers A or B only. I had a customer that had the same problem with a Sony receiver and we found that the A and B speakers are on. What seems to be the issue is that some older receivers are using the B channel amp for the surround speakers as well. Give it a try could not hurt.

WriteSimply · 12-11-2006, 11:58 PM

Does this problem exist when playing a DVD or HD source?

Hmm...that doesn't sound right. Sounds like they were referring to HDMI (1.1 vs. 1.3), not to the optical/coax. They were probably confused.

It plays fine on regular DVDs and on my HD-DVR.

pspoop · 12-12-2006, 03:44 PM

I'll try that again, but honestly, I think I changed just about every setting on my Receiver (including the speaker sets). I believe the model is the str de985. It's definitely an issue with the receiver though.

Any other thoughts?

Here's a link to my receiver
