Sblive optical spdif in : don't w

I want to use my sbli've 5. platinium to decode a dolby digital signal.
I use a optical wire.
Despite "ac3 decode" is enabled in the surround mixer, and that "spdif bypass" is not enabled, i don't hear anything!!
But when the optical signal is a stereo one, i have no problem (but i hear only stereo of course)
can anyone help me?

HELP!
There is no way to decode an external digital signal??

Optical SPDIF output stopped working- why?

I recently installed a larger HD and more RAM in my 1.63MHz Mini. After getting buttoned back up I noticed the optical SPDIF output stopped working (as in NO laser visible). Is there any possibility that this could be related to the OS (10.5.8)? Seems unlikely since it was fine before installation.
I really need this as it is my only option for interfacing with my playback system.

Hi Rich,
Long shot, but...
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.
Have you done a PRAM reset, CMD+Option+p+r...

Inspire 5700 optical SPDIF issue

I'm using my old Inspire 5700 for surround sound in the basement. I have my Directv HD reciever hooked up to it via optical spdif. I have the Directv receiver set to Dolby Digital. If I am watching a channel that is not DD and switch to a channel that is DD, the 5700 switches over to DD just fine. However, if I go back to a non DD channel, I get no sound. I either have to power off the 5700 and power it back on or hit the Pro Logic button on the remote to get sound back for the non DD channel.
Any ideas?

Well, here it is 2006 and people are still having problems with their inspire 5700 systems!! Amazing is'nt it's I bet you all thought I was gone forever but I'm not!! Do you think that Creative has determined that there is a problem with this system? Heck no!! you people are just unlucky according them. I'll be here forever because I don't like getting ripped off by big companies. Have a nice day and talk to you soon.

Qosmio G30-102 Optical SPDIF out not working

I have bought new Qosmio G30-102 and I am quite sure that SPDIF Optical Out connector is not working.
I can't test it at the moment, but I had a couple of SPDIF sound cards and every one of them had a red light on all the time, which signalized that Optical SPDIF is supported.

Hi,
maybe I would first try a SPDIF device, if I were you, because I agree with the user before, it has definetively a SPDIF out.

Is there a VI which reads audio signals off optical SPDIF port?

Hi,
I am trying to capture audio signals from a DAT unit on to the computer's hard drive. Could you please tell me how can I read these signals off an optical SPDIF port using Labview and save the streamed data as a wav file? I am using an audio capturing interface called the Edirol UA-5 to transfer the audio signals from the DAT unit to the Mac's hard drive.
Thanks,
Bhuvana

Hi Bhuvana,
There are not any VIs in LabVIEW designed specifically for SPDIF. There is, however, a tutorial on reading an SPDIF signal using LabVIEW FPGA. You may also be interested in this thread which discusses the use of a digital data acquisition board and the rate needed to read an SPDIF signal.

X-Fi support digital OPTICAL SPDIF outp

From what I've been able to tell so far is that the only way to get the optical output is to spend a lot of money on the platinum version of the X-Fi. Am I wrong or is Creative being creative in manipulating their sales and their bottom line?
Thank you.
ATTN Creative: We the consumers need an affordable X-Fi card with digital OPTICAL output without the front 5 /4 bay or the external platinum device! Space inside my PC is precious as I have a multimedia type microatx box. Get your engineers working on a solution!

I have nothing against the coaxial method, I just have mostly optical inputs in my yamaha reciever with the exeption of one thats coaxial but I believe my x-box is using that right now. Anyhow I looked all over the net for the digital kit and could not find one. I just have to ask what does creative have against them? To me it seems like their trying to skew the market towards their $400 dollar package. I don't know about you...

XFI Xtrememusic Optical SPDIF input problem

Hi everyone,
I am unable to utilise the optical input of the XFI to decode Dolby Digital / DTS streams.
Setup:
PS3 to Creative Digital I/O dongle via optical cable.
Creative Digital I/O to XFI Xtrememusic via provided connector.
PS3 playing a DVD with both DD and DTS soundtracks.
Problem:
No sound at all, no matter whether I choose DD or DTS.
If I set my PS3 to output only PCM audio, there is stereo sound heard, so I can confirm the physical connections are good.
I am unable to select any "SPDIF Input Settings" options in either the Creative Audio Console's "SPDIF I/O" tab or the Creative Volume Panel's "Digital I/O" section.
. Audio Console's drop-down list is greyed out and not selectable.
2. Volume Panel's "SPDIF Input Settings" drop-down list is not even visible. (i.e. there is nothing displayed to the right of "Digital Output Sampling Rate")
Steps taken to try to resolve issue:
. Checked Creative Website for latest drivers and applications and installed them.
2. Tried to follow the electronic guide/manual but could not choose "SPDIF Bypass" due to the missing "SPDIF Input Settings" option.
The online flash tutorial (Beginner's Guide -> Digital I/O) shows these settings but it is just empty for me on my computer.
Can anyone please tell me how I can get my Xtrememusic to decode DD/DTS via optical input? I've searched everywhere and found no answers. Thanks in advance!

Have you tried other device options in .asoundrc? According to the ALSA wiki, the digital device is the one marked IEC958. That would be card 1 device 1.
You might want to read that entire topic in the ALSA wiki if you have not done so already. It has methods for directly testing the digital output using aplay.

Optical SPDIF Problem

Hi. I have been using the optical output on my board to connect to my Logitech Z-680'z for a while without any problems. All of a sudden yesterday I turned on my speakers and I hear an awful hiss. They were in optical mode. If I start playing some audio while it is hissing, the hiss goes away, even if I pause it. It seems that if its not getting a signal it just plays loud static for some reason. It is very annoying and I am afraid I will blow my speakers eventually because of it. The analog outputs are fine but the quality isn't great with them. This could also be a problem with the Logitechs or the cable but I can't be sure what is causing it. Any suggestions? Thank you.

All drivers are the latest version and I have tried other ones as well. I can't put the speakers further from the monitor, but I am 100% sure that is not the problem. The sound that is coming out is basically white noise. I am thinking it is a problem with the optical cable, so I am going to get another one and see if that works.

SBLIVE 5.1 : dts drops using spdif under zoomplayer and recl

Hello there... I really need a big help.
I'm usign a personnale HT PC done with athlon 2800 XP, gforce 5200 and SBLIVE 5..
I plugged SBLIVE using spdif out connector to my sherwood R-945 ( DTS, DD, DPL ... ). Everything works fine under Dolby Digital 5. sound, except maybe some tearing and bypassed it using reclock.
Ok.
So I tried DTS sound, the sound seems to be really great ... except of : some drops which happens really randomly ... using again this spdif connector ..
Can someone have or had the same problem and found a solution ( drivers ... firmware ... configuration tools ).
Thx a lot,
Cyril

same here. Win7 media player isn't allowing me to go into "Advanced..." options to edit SPDIF settings, and VLC player SPDIF isnt working either.
The other strange thing I've noticed is that previously (in Vista64) I would only receive output to the optical when I specifically instructed applications to do so; however now in Win7 64 drivers I'm getting output to the optical from audio intended for 6 channel analogue. It seems like there's an option that is patching audio for the 6chan out to optical out. I am still getting output on the 6channel, but it is also goes to the optical.
This is a fresh install of Win7 64 and installed the SBXF_PCDRV_LB_2_8_003.exe drivers.

What is the SPDIF Optical Out meant for?

I have connected the optical s/pdif out from my Neo2 Platinum to my Panasonic 5.1 Receiver, but I can´t hear anything. The "red light" reaches the receiver, but it can´t decode the signal somehow. I had this with my Audigy 2 card: When I enabled "96khz" my receiver couldn´t read the signal, but when I changed this option to "48khz" it works perfectly. Unfortunately I can´t see this option within the AC97 drivers. So what can I do?
Yesterday I had PowerDVD and Winamp running side by side. I could actually hear the PowerDVD movie, but not the MP3 from Winamp. So it has something to do with the signal from the mainboard. How can I change this?

Quote from: bassmadrigal on 14-July-05, 15:42:01
The spdif out is only capable of relaying dolby encoded sound to the receiver. It is unable to transfer 2 channel..
Um. No.
Per the original question - the optical connector carries the exact same signal as the coaxial digital.
The funny truth is that SPDIF wasn't intended for listening. It was intended for karaoke. They thought they'd make CDs with the lyrics encoded in the less significant bits of the audio stream, and have the karaoke machine strip them out of the bitstream.
But audiophiles started using the SPDIF digital out on their CD players to connect them to audiophile-grade DACs.
Since it wasn't really designed for audio, there's some occasional (mostly insignificant) bit distortion, and the distortion can be made worse by a ground loop introduced by the shield on the coaxial connection.
The optical connection overcomes those issues pretty well. There's no electrical connection and thus no possibility of multiple paths to ground, and the data latches built into the optical transmitter and receiver guarantee that bits are better defined.
Don't pay a lot for optical spdif ("toslink") cables. The only feature worth anything is strain relief on the connector, to keep you from accidentally yanking the fiber out of the connector. The common plastic fiber works just as well as glass on hookups less than about 150 feet in length.
The relivant specifications are IEC60958 and IEC61937. Google for 'em, it's interesting reading.
ANYWAY, as per the specific question.
Pursuant to IEC60958 and AC97 specifications, and restricted by the choice of the ALC850 codec chip, the digital audio connectors on the Neo2 are capable of 48khz 16 bit transmissions.
This includes 48khz 16 bit PCM stereo audio and Dolby Digital compressed audio up to and including 48khz DTS.
Whether or not the windows drivers are capable of the dolby passthrough, i dunno, I've never booted windows on mine. Linux (with ALSA drivers) surely can.
Some audio codec chips are capable of more rates. IEC60958 and it's extensions allow for 32khz, 44.1khz and 96khz in addition to the AC97-mandated 48khz. 18 and 24 bit resolutions are also allowed.
If you intend to build a system for use as a home-theater PC, i highly recommend finding a motherboard with a codec that will at least do 44.1khz. Resampling the audio to 48khz can do horrible things to it. 32khz is only needed for some videos you might download from the internet, some VCDs, etc. You'd already know if you needed 96khz.
Your games are 5.1 but they are not encoding Dolby surround on the fly, so the digital connector is only going to get you 2 channels unless you are watching a DVD or something.
The exception is nForce2 SoundStorm boards, which have an on-the-fly dolby digital encoder.
Dolby is starting to license out their real-time encoder, so it may be possible in the future to buy a piece of software that will push your 6 channel game audio through your digital output.
This is why most surround receivers have a multi-channel input. You're just going to have to get a bunch of cables and run analog.
I also highly recommend that you invest in ground loop isolators.
Since your computer has a three-pronged power plug, it has it's own route to earth ground. Most stereo equipment does not.
When you plug the analog audio output from your computer into your home stereo receiver, in most cases you will hear a 60hz hum on the speakers. This is a harmless (but annoying) tone generated by the multiple paths to ground in your electrical connections.
I've had good experiences with RCA type ground loop isolators intended for car audio use. This has RCA connectors just like your stereo. You'll plug the isolator into the stereo and the computer into the isolator using normal audio cables.
I've had good experiences with Scosche ESO34 ground loop isolators. I've paid about $10/ea for them on ebay. You may pay as much as $15 or $20 for them at car audio specialty stores. Sometimes you can get them cheaper, especially if you're buying more than one of them.
Other RCA type ground isolators probably work just as well. I actually have a box of half a dozen of some other brand that i haven't tried yet, that i paid about $2/ea for.
Some come with brown wires dangling out of them, for earth ground. Personally i wouldn't connect them to anything.
Some of the nicer sound cards - most of the Audigy line for example - has on-card ground isolation, and won't need an outboard isolator. Motherboard audio almost certainly does not have ground isolation.

Audigy 4 Pro - can only get 2 channel sound via SPDIF/optical connecti

I have two PC's, one with an Audigy 4 Pro and one with an Audigy 2 Platinum (A2P), I have my 5. speakers hooked up to the A2P and the A4P connected via the SPDIF to the A2P, I would expect to get 5. - both are setup to use 5. speakers, (I know that as a standard Digital coax/optical connections should handle multi speaker configs my entire A/V sound system (7. Dolby) uses optical and coax and it works fine).
If I run the channel test on the Audigy 4 I can get nothing but sound through the left and right speakers, if I run the test on the Audigy 2 (speakers direct connected) the sound is fine, if I reconnect the speakers to my Audigy 4 I get sound on all speakers so it looks like its an issue with the SPDIF and optical inputs (I tried both).
I have emailed tech support, I'm waiting for them to come back and tell me that the Audigy 4 cannot transmit more than two channels down the SPDIF/optical outs, thats my suspicion anyway, if that is the case then I'm not going to be a happy man and the Audigy will be going back to the store. Could be a driver problem of course as I cant believe they would implement Dolby and THX and only transmit two channels on the optical outs, that would be a bit dumb considering the primary use for digital connections is sound system interconnects.
Anyone with any ideas about this let me know, perhaps theres a hidden setting somewhere or a registry setting that switches the digital outs to carry all signals.

Just before everyone kicks off, heres a response I got from a tech guy at Creative themselves.
If you connect speakers to your sound card using a digital cable
(RCA/SPDIF or optical) then the software speaker test will only output
from two speakers. The reason for this is that the speaker test signal is
not in AC3 nor DTS format.
The signal on a digital connection is either
Optical SPDIF - which is either Stereo PCM signal or AC-3/DTS Bitstream
RCA SPDIF - which is either Stereo PCM signal or AC-3/DTS Bitstream
If you play AC3 (Dolby Digital) or DTS encoded signals, the amplifier
decodes this and outputs it to all 6 speakers (5 satellites & subwoofer)
discretely.
When playing back stereo signals (such as Wav/CD Audio or MP3/WMA files)
the amplifier may generate 5. output based on the incoming stereo PCM
signal, provided Dolby Pro Logic decoding is available and activated.
Therefore the speaker test should not be relied on when using RCA or
Optical digital connections.
This applies to all speaker systems equipped with RCA or Optical digital
connections.
This makes sense to me and I'm pretty happy with it, basically as the reply says above the speaker test does not encode to AC3 hence if you hook two Audigys together and run the test you only get 2 channel output, if you play a DVD which is AC3/DTS encoded on one Audigy and listen to speakers hooked up to the other when both Audigys are connected via SPDIF or optical you should in theory get full playback on all speakers. Hopefully
Cheers

Analog/6 channel direct or SPDIF/optical for dvd playba

Using x-fi platinum.
Just wondering if anyone knows which is best for dvd/BLU RAY?audio, I have the X-fi hooked to logitech's z5500 both analog and optical/spdif. I use the 6 channel direct/analog when I game for EAX effects and optical for music and movie playback. I never really explored the pros and cons using the analog for straight Movie play back till recentily and?I ?can't seem to find any info on Google about this. I just want to know which is best, analog or spidif for movie play back? I can get 5. surround sound either way though just need to know which method is the better. IF the speakers were PCM 5. would know which way to go but they aren'. Any thoughts would be nice.

So no one has any thoughts on this?

Can anyone confirm spdif in (optical/coax) on xfi DD/DTS decoding in vis

Doesn't work here, and I thought the X-Fi's could decode DTS/DD streams coming from other sources. I get no sound when connecting to the digital i/o adapter (the one that plugs into the flexijack), and I've hunted out enable digital io under speaker output playback device, and adjusted all levels and selected digital in as recording default device. Anyone have their Xfis decoding digital streams from external devices like xbox's or the like in Vista?

Decoding cannot be done through the flexijack at the back. If you want to decode something using an optical cable (I don't know if they have coaxial, but probably), you'll have to buy the dri've bay console or the external box thing. Neither are cheap, neither are?a neat way of doing it if you want to keep the connection permanent. I have (or had now that I'm using mobo sound with Vista) my PS2 plugged into the optical port and then the flexijack. Works fine for normal sound, but enable Dolby or DTS and it stops working. There is a discussion somewhere else on the forums about trying to decode things with the flexijack, and it's basically impossible. Hacking the drivers to enable the option didn't work. At least it's not something you can blame on Vista!Message Edited by Silent_Shark on 2-22-20060:29 AM
