PS3 5.1 surround sound problem

[colspark]

It seems it's the hd audio formats causing the problem, as you're outputting lpcm over hdmi to your tv and then the tv is trying to pass that on via digital coax to your amp. It's then reverting to 2ch audio.

Correct me if i'm wrong - that's how i read your setup!

If you change audio output over hdmi to bitstream it should only send dd / dts on, as ps3 cannot send hd audio as bitstream.

That might fix it? I assume your tv is capable of passing on 5.1ch bitstream and not just stereo output!

Have you considered just connecting ps3 to your amp directly with optical or an optical / digital coax converter? Might make it a bit less complicated!

It's not in the blueray menu
I think you need to go to sound settings, you should then get a horizontal sub menu (shows HDMI / optical out etc) scroll right once and all the sound settings should be there. Deselect digital 5.1 (it's the only one you can try) you should still have the other 5.1 highlighted (is it dts?). Hopefully this should work as I would have thought that no lossless sound will be sent to the telly. Saying that these things are never simple

Colspark, why would he get 5.1 for DVD's and games though?

[colspark]

I think it's to do with the higher bitrate of the core dd / dts track on blu rays. It's not dthd / dts hd ma, but still superior to standard dd / dts. Perhaps the digital coax can't handle it or tv can't output it?

Could try firstly ensuring audio output is bitstream over hdmi (because lpcm is too much for the digital coax to take from tv to the amp), then do custom sound settings and only tick 5.1ch dd and dts. Might sort it!

EDIT- i see that's pretty much exactly what you've suggested sheff!

Good stuff lot for me to try when I get home!

Looking forward to the wife tutting at me as i click from blueray to setting menu when all she wants to do is watch telly!

Oh I could just connect to your amp directly with optical or an optical / digital coax converter but then my xbox would have no sound. Ahh thought these things were getting simplier.

Colspark, you need to put 'Make sure your audio is set to bitstream' as your footline. I'm sure I've seen you type that more than anything else on here

That's why you find so many on here go for a seperate AV Receiver/Speaker setup. Plenty of inputs for all your toys

Might be worth investing in an optical switch to give you the extra inputs to your home theatre. The sound quality will be greatly enhanced in comparison to the pro-logic version you currently are getting from routing audio through the TV.

Must get me an Onkyo. Have seen this and the 806 on offer in Richer Sounds in the past couple of weeks. I guess you have too if you're the same Uridium from HUKD How to convince 'the boss' of our need for a new receiver is a tricky one.

heh! Yes, "bitstream over optical" and "lpcm over hdmi"- i can type those really really fast now!

as Lee12 said, it would seem the better option, if you have optical input, to just get an optical switch and connect your ps3 and xbox360 direct to your surround.

I don't know much about digital coax, but if it can't handle the higher bitrate of the dd / dts core tracks on blu ray, and that's causing the problem, that might be your only way round it...

You have more HDMI inputs then me Got meself the 605 which only has x2 HDMI but I have the PS3/EP30 plugged up via HDMI. I was worried because I could not do the SkyHD but to my understanding SkyHD only sends 2 channel via HDMI and 5.1 via OPTICAL.

Well I tried and failed still does the annoy clicking noise and comes out in pro logic. Now I have to face up to it's either xbox or ps3 for 5.1. It not fair as there's no real logical reason for it! Bloody sony.


Thanks for all your help.

Get one of these for a tenner then connect from PS3 direct to your surround system

Do you know of a godd optical switch, this may be the solution..
