Lost Dolby Digital 5.1 signal

Soundblaster Live Platinum, DTT2500, PowerDVD6.0
Connected by SPDIF Out from Front (Live Drive)
Somehow i have lost the signal for Dolby Digital Signal 5., I know the AC-3 is working and i hear my DVD's thru the front cable.... I am using XPSP2....and of course, have SPDIF bypass enabled...
is it possible that the decoder part of the DTT2500 burned out?....(as a last attempt, i have ordered the cables to connect from the rear digital outlet i.e. to the nine pin mini-din)...
all speakers work when in the Music mode,,,
i have gotten good use from this combination of Creative products
(self built computer)

Jswcpm,
Well, if SPDIF bypass is enabled in both the DVD software and the sound card then the only other thing left to check is the cables. If the new ones fail to work, then it would appear that the decoder has gone out on the DTT2500. If this turns out to be the case there are a few options you can try (and may be surprised at how much speakers have progressed since the DTT2500's). First off things have moved away from the combined package of decoder and speakers in one product. The reason for this is that it gives you a choice in how to combine things. First off you select a set of speakers that fit your requirements. In your case I would suggest either the Inspire T7700 (7.1) or T5400 (5.1) since they are sub $100 speakers that still surpass the wattage and sound reproduction of the DTT2500's. Here are their webpages:
T7700 - http://us.creative.com/products/prod...3&product=5076
T5400 - http://us.creative.com/products/prod...5&product=5077
Then you need to select what kind of decoder you wish to use. You can choose to purchase a new sound card that has a built in decoder. This is especially good if you are just needing to decode audio from sources on your computer (no external sources). If this is the case then you need to look at what the speakers you have can do. If you get 7. then you will want at least the Sound Blaster Audigy 2 Value, however the Audigy 2 ZS is probably the option I would suggest (it does DTS and DVD-Audio disks).
Audigy 2 Value: http://us.creative.com/products/prod...4&product=0653
Audigy 2 ZS: http://us.creative.com/products/prod...04&product=495
If you have the 5.1 speakers then you will be able to use the Live! 5.1 (not the Live! 24bit or Live! LS) or Audigy LS.
Live! 5.1: http://us.creative.com/products/prod...206&product=50
Audigy LS: http://us.creative.com/products/prod...05&product=923
If you want to continue using your current sound card (I wouldn't suggest this as your card is 4.1) then you can use an external decoder like the DDTS-100. This will give you 4.1 in Direct Sound (game and windows audio) and 5.1, 6.1, and 7.1 (with upmix on 7.1 speakers) with DVD movies.

I hope this helps you out.

Dolby Digital/AC3 encoding?

I just bought a K8N Neo4, and hooked it up to my Panasonic audio receiver - just the one cable, S/PDIF optical. I was hoping to get 5.1 sound out of this, but all I get is two channel stereo.
Is there any way to encode a signal that my receiver can use to produce full surround sound (it supports Dolby Digital and DTS signals)?

Nice.
I never even heard of it. I always thought the only way was to go 6ch analog and have your external amp support multi channel in if the source wasn't DD/DTS already in which case it's not DD anyway. Otherwise you only get 2ch PCM on the SPDIF. Then again I only have owned Creative sound cards....geez even then Creative made you buy the breakout box to enable AC3 decoding unless you made a board mod... Of course you still need a multi channel source. What kind of software do they come with? Can you play a 6ch .wav for example and have a DD/DTS stream over SPDIF/Optical? or is only really for games, so for simplicity you can have one cable/fiber and not go analog till it 's on the way to the speakers? Still though except for a few less cables, and when the D/A conversion takes place(and therefore the quality of which component is doing it, sound card or amp) I don't think it's that big of a deal if you have multichannel input amp. DD is still not lossless compression so the big advantage would seem to be for those without multichannel inputs. Otherwise it would be an interesting comparrision for the audiophile which I'm not. You have a pure source and you compress to DD and lose quality and then decode and output vs. Pure source going analog, losing signal quality along the way and outputting. someone on the internet has surely done it.

AUZENTECH, " Dolby Digital Live " Coming 12/21/07 for X-fi Prel

http://www.auzentech.com/site/index.php When Dolby/DTS for the rest?

Wonderful!! I'm d/l this 47MB driver now... will post results after trying............. Something I want to say, I really want Creative can hear us -- your customer that Vista could support driver level decode of Dolby Digital and DST signals and do not let us use software/filters to decode that. I compared the hardware/driver level and PowerDVD/AC3filter decoding of DTS/DD under Windows XP, very huge difference in sound quality!!!!!! I originally buy the X-Fi elite pro is for its hardware decoding capabilities, but now the capabilities disappear on Windows Vista!!!!!!!!!!!!! It is said this is because copyrights issues!!!!!!! I wanna ask there will not be copyrights issues under Windows XP ! !
If there really copyrights issues under Vista, I hope Creative can release a standalone driver patch for us to buy for the hardware DD/DTS capabilities under Vista!!!! I really want Creative can hear us!! Please consider!!!!!
Thanks,Ter

TS5150 Does the optical digital audio port send out a Dolby Digital signal

Does the optical digital audio port send out a Dolby Digital signal

Yes if the media has such an audio track available it can do so.
There is a setting for audio and video allowing DD output to be set for Auto (on/off if connected HDMI device can decode DD), On or Off.
AC

TS5150 No Dolby digital, only PCM 2ch @ 48 k. Tried every method. Get DD with xbox360 on Netflix but only PCM on Apple TV .

I can't get my Apple TV to send a Dolby Digital signal to my receiver. I have tried going through my tv, HDMI in optical out to the receiver, optical direct. Switching DD on and off in the settings menu, ext. if I use Netflix on my xbox it's in DD no issues. I have a Rotel RSX 1065. I know that it is not the issue. If I disconnect the optical cable from the Apple TV the signal is lost, not an input conflict. Reconnect and it's in PCM 2ch @48k.

Hold select down when playing in Netflix to see if it give you any audio options.
Also it is not necessarily the case that Netflix uses the same media file for all devices - the servers may be tailored to feed an optimised file for the device playing it back.

HD TV Show... can't get Dolby Digital 5.1 to Work

I just bought an episode of Chuck (from NBC). In the description of the show it says that it has Dolby Digital 5.1 Surround Sound. I have my macbook-pro hooked up to my surround sound system using a mini-toslink -> optical connector. When playing the episode the Stereo track plays just fine... but if I switch to Surround.... I get no sound.
Any ideas?

I bought LOST season 5 season pass.
I only found out about this 'non-feature' after trying for ages to get it to work and searching for a solution.
When I first complained I got told by support that it was probably a hardware issue and to call the support line. I did, got the same answer, and was then asked to part with more money for continued support, which I declined. I asked point blank whether DD5.1 really only plays back on Apple TV - which was denied.
After continuing to pursue it I finally got an email from 'tier 2' support admitting that 5.1 does only plays back on an Apple TV: here's the text:
+This is+ name removed +from iTunes Store Customer Support and your request+
+has been escalated to me today. I understand that you have been+
+unable to use Dolby surround sound on your computer for your iTunes+
+Store purchases.+
+Dolby 5.1 surround sound is currently only available for the Apple+
+TV. Apple recognizes that no one is better qualified to provide+
+feedback about the content provided on the iTunes Store than the+
+people who use it.+
I got back to them to say I'd like a (small!) partial refund - to cover the costs of my phone bills and disappointment. They've gone silent.
I've now reported it to Trading Standards in the UK as it is misselling. Curiously - since i complained the 'About HD' section - where it used to say +on your Apple TV or Computer+ has been changed.

Dolby digital via Toslink

Hardware
Mac mini (mid 2011)
Yamaha YAS-101
I've connected a mini to a Yamaha YAS-101 via Toslink hoping to receive Dolby Digital 5.1. The problem is that the YAS-101 detects the signal as stereo. I was under the impression that it shouldn't be a problem to achieve this via Toslink? Tested with Itunes and VLC.
The YAS-101 detects DD when playing a bluray from a PS3 so shouldn't be a problem there.
Thankful for any help.

If your Mac Mini has a HDMI port, it's one of the few Apple products that does audio (5.1) and video through the HDMI port.

TS3518 Dolby digital from Apple TV

This used to work fine before the last update. What did apple do for this not to work. I have HDMI out of my Apple TV into my surround sound receiver which decodes dolby digital. I have to turn off dolby digital to get audio. the whole point of using a surround recieve is to use dolby surround. There is no point of renting movies from Apple TV wiothout surround sound capabilities. Why is this not working?

My experience is the same. Loss of Dolby Digital 5.1 output. Amplifier (Yamaha) indicating "PCM" signal, instead of DD. So far, no acknowledgment of the issue from Apple.

Stereo Sound to Rear Speakers Only / Dolby Digital

Just purchased a Toshiba 40S51U LCD TV. Having an issue with the sound when connected to a receiver via the optical out.
I think the issue is as follows: When the program (ie local news) or commercial is broadcast in stereo, the sound is sent only to the surround (rear) speakers. Sound is great (surround works just fine) when watching a show. Assuming the shows are broadcasting 5.1 sound, local news only 2.0.
Signal is over-the-air.
I can switch the sound output to PCM and get reasonable sound for everything, but obviously lose the surround sound. Would like to keep the system in Dolby Digital (AUTO) all the time.
Thanks,
Rob
Solved!
Go to Solution.

Me again -- I'm an idiot and the TV was just fine.
My receiver was set to a non-connected set of speakers -- not sure why anything was working! I changed the speakers to the set actually connected and everything seems to be working OK now. The optical out on the TV was likely never an issue.

Decode Dolby Digital from optical inpu

Hi,
I bought SB X-Fi Extreme Audio PCIE. I know it'sdoesn't have?any hardware supported features, but maybe there is some?software way to decode Dolby Digital send throught optical cable to SB input ?
Second question - which SB model should I buy to get this working ?

I don't think the Audigy 2 NX has decoding hardware onboard, it uses a driver based decoder therfore all decoding is done by the computer. The Extigy is different, it has and actual onboard decoder so it can be used as a stand-alone Dolby Digital decoder, not requiring a computer to operate. I'm not sure whether the NX can decode AC3 from an external source or if it is limited to decoding signals originating from the computer (i.e DVD or AC3 file).

How do I get Dolby digital live or DTS connect to work?

I have the sound blaster Zx sound card and the logitech z906 5.1 surround speaker system. I am connecting to the speakers via optical cable. I figured Dolby digital live and/or DTS would sound great with this set up, only problem when I turn on either of those my speakers go silent. I set Speakers: Soundblaster Z as my default playback device but other than that I am not sure what I need to do to get it to work.
Bruce

I have the z 906 speakers, not the Z-5500 in your link. The manual I already have says the z906 speakers automatically detect the digital signal. I figured the Sound Blaster card would convert an analog signal to digital since it is going into the speakers through the Optical cable, I guess I was wrong.
I have read the link about digital connections on these forums along with the notice in the cinematic tab in the Sound Blaster control panel. I believe they are both saying that I will not be able to use my music player (windows media player) in conjunction with the Dolby DTS and Dolby Digital Live, is this true?
If so then is the only way to listen to the DTS or digital Live effects is through a DVD or Blu ray disc encoded for either of those effects?
If this is true how do I test my dolby digital outputs to make sure they are working correctly?

Proper 5.1 Dolby Digital using Optical in on Audigy 2 ZS

As of yesterday night, I have connected my PS3 to my Audigy 2 ZS via optical in, so that i could hear 5.1 from my PC sound system (Klipsch Promedia Ultra 5.1).From what i've heard somewhere (I don't know if it's true) you need audio to be in the bitstream format in order to hear proper dolby digital 5.1 when using an optical cable. When selecting the (PS3 MENU) Blu-ray optical out as LPCM, I've managed to get audio to all speakers (including subwoofer (doesn't sound like proper LFE emission)) but it'sjust sounds like stereo on each channel, not the proper discrete surround sound. When I set my Blur-ray disc optical out to bitstream (hoping to hear real 5.1) I hear no audio during the film (although somehow on one test i heard sound in the menu). How do i get my sound card to recognize and decode the bitstream format so I can hear dolby 5.1 or is an LPCM signal sufficient for proper 5.1 In the creative audioHQ, I have set the digital input to Dolby Digital/DTS SPDIF-in Decode. This is the only change I have made (on the PC)so far to hear 5.1 sound from an external device (I also got the sound card to recognize the SPDIF-in). Is there more I am supposed to do, or is it enough? Is the AC3 audio filter neccessary for my situation? For additional information, (In the above setups) i do not get audio for DVDs or games (these could be PS3 issues)?Any advice or information would be greatly appreciated?Thanks!

Here is perhaps a better reply ....
The only 5. compressed signal the Video Editor (or the NX) can play is one that originates on the host - via a DVD player like InterVideo or Cyberlink, or from Creative Media Source application - the digital stream is decoded in the driver and then sent to the external device. It cannot act as a stand-alone decoder box in which the signal originates from the S/PDIF jack.

Netflix Dolby Digital 5.1 gone after udpate

Hi,
Is anybody (or everybody) else having that problem ?
Last week I was playing Netflix movies in Dolby Digital 5.1 but now the same movies on the same hardware (Apple TV/ AV reciver) are not Dolby Digital anymore but only prologic.
Other Apple TV items (ie. movies, shows, itunes festival) have no problems streaming in 5.1.
It look like this happen at the time of the latest Apple TV OS update.
Is this a Netflix issue or a Apple issue ?
Tried to contact Netflix....they don't have a clue.
PS, I have the latest generation of Apple TV and I update my Apple TV OS last week (so i'm up to date).

I've encountered the exact same issue. Ever since the latest Apple firmware update I can't get the Netflix app to send a Dolby Digital signal to my receiver. I've tried everything but it just does Pro Logic II. This is for content on Netflix that I know is Dolby Digital 5.1 supported.
As you've said, Dolby Digital still works fine for other content (iTunes festival, movies, etc) but Netflix doesn't seem to trigger it. Something is not quite right with this firmware and Dolby Digital. I can't remember for sure now but I think that, before this firmware, my receiver always had the Dolby Digital light on when the Apple TV was on (even when on the home screen). It now seems to be Pro Logic II all the time except for specific content.
