BluRay Audio Problem

[boise49ers]

I have my bluray running through HDMI and the audio ran fine. Now I have hooked that machine with Bluray to projector and run a Optical audio out. Everything works with optical out in Dolby Digital except the Bluray. No audio at all. It is a Sata drive. Any idea what maybe wrong. Thanks

Did you check Control Panel/Hardware and Sound/Manage Audio Devices? There you usually have to find your Digital Audio (S/PDIF) and make sure it's enabled, and also make sure your AMD HDMI Output isn't the default. That should work.

Are you running thru a receiver?

 

[boise49ers]

Are you running thru a receiver?

Yep and the computer programs such as games and internet work fine,
it is just the disk drive that doesn't work.

 

[Mussels]

optical isnt compatible with some HDMI audio standards (namely, anything not DD/DTS) so isnt it just possible you're playing back streams your decoder cant play?

 

[Jetster]

Or you dont have optical checked in FFshow

 

[H82LUZ73]

you using your AMD Hdimi sound out to the av/receiver So what is it that you use for Blu Ray playback PDVD10-11 ?Make sure you set it to non decoded high-definition audio source to external device.As for playing games with Dolby Digital you cant` unless the av/receiver has the option.

 

[boise49ers]

I'm using the Realtek optical out. ATI high Def Audio is disabled. The games and all programs
play Dolby Digital. The disk drive is the only devise not playing any audio.
I tried to update the firmware , but says the best driver is already installed.

What is FF show ?

What is FF show ?

here u go: http://sourceforge.net/projects/ffdshow/

i hope that helps ^^;

 

[boise49ers]

here u go: http://sourceforge.net/projects/ffdshow/

i hope that helps ^^;

Downloaded at and the install instructions say run Exe. File,
But there is no exe. file when I extracted all the files. I'll look
for it elsewhere. Thanks

 

[Shou Miko]

i only use FFShow with Combined Community Codec Pack (CCCP) myself.

http://www.cccp-project.net/ for files and for DVD and Discs it's PowerDVD 11 ^^;

 

[Jetster]

Bingo ^^

 

[Mussels]

its FFDshow, btw guys.

and yes, i use it with CCCP as well.


i still think he's trying to send an incompatible audio stream over SPDIF.

It's a possibility..but.

Most receivers will downscale Dolby True HD 7.1 to regular Dolby Digital 5.1 or downscale DTS HD Masters 7.1 to regular DTS 5.1 if the receiver is incapable of processing the new HD formats.

 

[H82LUZ73]

yes he is ,if he wants all the digital signals to the av/receiver he needs to use the amd hdmi out,if the only thing not playing out is blu ray.The optical on board will not allow uncompressed signals.He will only get pcm or just Dolby digital.Not the DTS Master HD or Dolby HD.I have Power DVD11 and need it set for AMD/ hdmi out(actually has no effect on gam eplay too i use it for primary out) and non decoded high-definition audio source to external device for blu rays.These can be found under the audio options in PDVD11 and the non decoded will only show up when there is blu ray present.

Yes But 95% of the movies out there (yes i watch a lot of them )Are only DTS master 5.1 maybe about lets say i watch 24 movies in a week only one will be in full 7.1.It is cheaper and quicker for them to use 5.1 .Only Big money makers movies like lets say THOR will be 7.1 but other blockbusters will be 5.1 like Green Lantern.

Not if it cant get to it. SPDIF

That sucks, doesn't SPDIF work with a Dolby Digital Plus (DD+) sound track?

I guess the OP needs HDMI then. BTW I'm looking to upgrade to a HD compatible receiver myself soon.


Edit:

H82LUZ73, so only DD True HD 5.1 and DTS HD Masters 5.1 can be downscaled to regular DD 5.1 and DTS 5.1 over SPDIF. Whereas the DD True HD 7.1 and DTS HD Masters 7.1 can NOT be downscaled to regular DD 5.1 and DTS 5.1 over SPDIF. Is that correct?

no they are a different breed all together,If you try playing them over spdif you will either get

PCM format (most of the time this)
Dolby Digital (if the blu ray has the option)

most of the time it comes pcm to the receiver.

And yes HDMI is the better of the too if you watch Blu Rays .

As for receivers ,I recommend Onkyo,Dennon ...You might pay a little more but the customer service (with Onkyo right now) is awesome.Dennon has about the same too.

See I thought SPDIF was bandwith limited to 5.1 compressed stream, and HDMI really just bumped up the bandwith for 7.1 UNcompressed and consequentially had enough room for video too?

that is how it works. but if you try and send 7.1, or 5,1 UNcompressed over SPDIF, then the receiver gets no signal it can understand, so no audio.

Yes, thats correct. 5.1 compressed is basically DD 5.1 and DTS 5.1

HDMI does do video and uncompressed audio which is multi channel PCM, DD True HD and DTS Masters upto 7.1.

So your assumptions are correct

 

[7.62]

Well yes, but it doesnt solve OP problem. Is he trying to send 'native' bluray audio down a DVD stream?
He said that it used to work. I think he is sending UNcompressed audio to a reciever that like compressed audio.

we wont know until he tells us what audio streams he's sending.

He aka Me gave up and went back to analog and I'm running Dolby PLII instead.
Tired of fighting it. Still sounds OK.
