Optical out weird problem

Hi, i've a really weird problem on my mbp audio out. Apparently the optical out seems to go in "sleep" mode in less than a second of inactivity, turning off the speakers which takes like a second to turn on.
The result is that any short, silent-preceeded sound is completely not played.
The behaviour is also described in this thread.

I am also noticing this problem. I have my iMac connected to an Apogee Mini-DAC via optical TOSLINK. I thought I had a bad cable, so I bought a new one, but it's still losing its connection. Now I can definitely say it's the Mac and not the DAC because I will unplug the cable from the Mini-DAC but leave it connected to the Mac. If I play something in iTunes, the red light shines through the cable, but if I stop the song, after a few seconds the light goes out. So, this is not limited to MBP. I have a suspicion that this is a "feature" in order to cut down on energy use, but it sure is annoying.

CLL and Optical Out major problem

So I recently purchased a X-Fi Titanium Fatalty Professional card, I'm using optical out to my 5.1 surround system.
Is Creative Console Launcher not supposed to work with using optical out? It seems to only be reconizing Line Out -4. (Pic Included) I currently get 2.1 sound, but nothing else. Not even with games/DVD's.
I'm using Win7x64 on a fresh install. I have all the proper drivers that I know of.

SB Xtreme Audio Notebook optical out problem with Home TheaterSystem-HELP!

JSB Xtreme Audio Notebook optical out problem with Home TheaterSystem-HELP!, I have this sound card connected?(optical OUT) ?to my home?theater system's digital IN ?through the recommended /8in. optical miniplug-to-optical SPDIF cable. Theater system is set correctly to Digital-In mode. I have no sound!
The cable is a Velocity Toslink-to-Optical Mini Plug digital cable. I don't see any settings in the Creative Console Launcher. The notebook is a Dell XPS M730 (Vista 32).
I have a PS3, DirecTV, and the SB Xtreme Audio Notebook cable on a hub switch that connects to the system's?one Optical IN. The PS3 and DirecTV sound perfect!
The sound card works fine with standard PC speakers. I'm at a loss as?to what to try next. I set this whole system up myself, so I'm pretty good at working out the kinks, except this one!
Karen

OK. I just went to Control Panel - Sound - Playback - Digital Output Device (SB Xtreme Audio Notebook) - Properties - Advanced. I experimented with different sample rates and bit depths. Clicked the test button and lo and behold - sound from the HTS! I've tried iTunes, PowerDVD (configured to digital output) and YouTube - no sound! Am I missing something really obvious?
HA! Just backed out to Playback and selected Digital Output Device (SPDIF) and set as Default. Sound is emunating from HTS! Well, that mystery is solved! Who knew.
Thanks anyway! Any comments or advice will still be appreciated.

Optical out problem

All,
I have a white imac and have recently bought a receiver and 5.1 speakers to go with it. I have connected up amp to PS3 through optical cable and it works fine, but I am hoping to connect my mac straight up to the receiver through the optical out.
I have got the required "mini-optical" extension for my standard optical cable, and then plugged it into the amp but no noise!!!
Looking in the settings on mac it see's that the optical is plugged in, but I still can't get anything out the speakers - any ideas?
It is my girlfriends 25th birthday on Friday and I really need the speakers all woking for then!!!
Cheers
James

Thanks for the reply but i'm running Power DVD Delux and even earlier versions of Power DVD had 5. as standard. I think this is not the problem though. I don't want Power DVD to decode the AC3 I want it to pass through the card to my Yamaha Recei'ver and have that decode the AC3 tracks on both Divx and DVDs. So I click the box that says Digital Output Only and it makes no difference!
I did get this to work about a month after buying the card back in September 2006 now it aint working. I've tried every trick in the book from re-install (6 times) to a cleam boot in XP!!!! nothing works! could it be a duff card!
Remember there's a prize for whoever can solve this!

Having problem with optical out on HD rental movie

Hi all, I just bought an Apple TV for myself for the holidays. I have the optical out going to a DAC then to my stereo, and it works fine for music, Netflix, and iTunes Radio. However, when I rented a movie via iTunes (The Wolverine), optical out no longer worked. I did get sound through HDMI (and thus through my TV--not great, but usable).
Because this is a pure DAC (no Dolby), I had to turn Dolby Digital to Off to get Netflix to work. I tried Audio Output as both Auto and 16 bit, and neither setting worked. Audio Output = Auto works fine for everything else.
Anybody else have a similar issue? Thanks!

Turning Dolby Digital off shouldn't mean not getting any signal out of optical out. I turned it off when I had problems with Netflix movies, but now Netflix movies are fine. I'm getting sound out of optical out with them, which means that something is converting the sound signal to PCM.
The problem is that the conversion doesn't appear to be happening for iTunes movie rentals for some reason.

Digital Optical Out problem on USB LIVE Exter

Jpc's guide to digital outputs was great but it didn't seem to address the problems I'm having with my Soundblaster LIVE USB External! I've contacted support on numerous occasions but with no solution...can anybody help me?My Problem:?I have the Soundblaster LIVE USB External Card and I'm trying to play DIVX movies with AC3 soundtracks in VLC media player and also standard DVDs with Dolby Digital 5. soundtracks using both WINDVD and PowerDVD. The Soundblaster is connected to my YAMAHA Home Cinema Recei'ver via the front Optical out (Not the Rear Coax SPDIF) and the amp is set to decode DD or DTS. I have my speaker settings in the Creative Soundblaster software set to Optical Out Only (the little checkbox) and the speakers are then fixed on 2.. In VLC Media player I've selected SPDIF output and I am getting sound but it's just stereo and the Recei'ver is showing that it's receiving a PCM sound signal. In PowerDVD under the config it shows that the Soundblaster is (in use) but under SPDIF is shows (not in use) and I can find no options in Power DVD to select SPDIF! Again I am getting sound but not full-on DD 5.. In WINDVD under sound config is shows options for selecting SPDIF but it's greyed out and unselectable! The only thing that is slected is Analog sound device! I have sound, again stereo!?So that's it really... I'm just trying to figure out why I am getting sound (in stereo only) but nothing that I try will give me full 5.! I understand the concept that ticking the Optical Output only box in the Creative Soundblaster software should then send a pure AC3 signal to the receiver and that should then decode it as it would a DVD from a DVD player! I have tested the front port of my Recei'ver with a set top DVD player and It gives my 5. with no problem!?Any help would be fab!?I'm so at my wits end with this that I'll offer a prize to anyone who can solve this for me!?CheersOlyMessage Edited by olyscott8 on 03-9-200705:48 AM

Optical Out 5.1 not working

Optical Out 5. not working?Hi everyone.
I have a Sound Blaster X-Fi Xtreme Audio PCI Express card on a windows XP SP3 PC.
I connected the optical OUT to a Sony 5. Home Theather system, DTS and Dolby Digital capable.
When I configure the creative console to output 5. channels, and use the tone or channel tests, I can only hear the front left and front right channels, the others make no sound. My receiver says it's receiving a 2.0 signal, but If I listen to stereo music files or movies, the sound comes out wrong, with low volume and a weird metallic sound. If I set the console to 2., this problem disapears.
Using powerDVD with a 5. DVD, and setting it's options to SPDIF passthrough, the sound it's a perfect 5..
The same happens with Mediaplayer classic using the AC3Filters, and configuring the filter for SPDIF passthrough.
The problem is that the Creative Console doesn't let me choose SPDIF passthrough, I don't have the Digital I/O icon that the help describes and I don't have the mode switcher (it's fixed on Entertainment mode).
What am I doing wrong?
thanks everyone and excuse my broken English.

Re: Optical Out 5. not working
Sorry, I mistook your card for another model. There is no option to select SPDIF passthrough. The Digital Out for this card is always on.
Please note that optical cable will only carry pcm stereo or compressed bit stream AC3, dts. That's the reason you are getting stereo when stereo music files. How many channels you get when playing movies depends on how the movie is encoded too.
I am not sure what is that weird metallic sound, it would be advisable to contact Customer Support to see if they can help you on this.
Sorry, I mistook your card for another model. You are right, there is no option to select SPDIF passthrough. There is no need to, because the Digital Out for this card is always on. Based on your posting, your Home Theater System is already doing the decoding. Please note that optical cable will only carry pcm stereo or compressed bit stream AC3, DTS.

Optical Out to Z-

Hi all, was just trying to play some DVD with the optical out from my X-fi going into my Z-680. I enabled DTS bitstream out in the hope that the decoder on my speaker will do the decoding..but I just got some weird scratchy noise..
Was wondering if anyone could point me in the correct direction?:smileyindifferent:
Currently using WinDVD 5

I have been having the same trouble. Not so much with DVDs but more with games. Like World of warcraft it happens at least once every 5 min and get very irritating so much so i often just shut off the sound which is a shame since i spent all the time and money to have such a great system. can anyone help. I have heard there are problems with the codecs between the longitech 7-680 speakers and sound blaster cards, but i was wondering if anyone had any way to combat this problem. thanks

Xtremegamer no output from optical out in Vista 64.

Hello,
I spent over 2 weeks going over those forums and goggling around the problem I have. ?
Ever since I upgraded from Vista x86 to Vista x64 I cannot get the sound out through my digital out (flexijack) connection. I am connecting to Onkyo SR800 ( I don't think Onkyo is causing the problem since it worked before)
Here is what I tried:
. I verified the optical cable and mini-toslink adapter work.
2 I tried latest drivers from Creative site.
3. I tried older drivers ( SBXF_PCDVT_LB_2_5_0004,? SBXF_PCDVT_LB_2_5_0002 ?SBXF_PCDRV_LB_2_5_0006)
4. I tried changing spdif out to default audio device in vista.
5. I tried changing sampling rate from 48 to 96 Hz in audio console.
6. I readjusted all volume controls in both vista and creative to the maximum.
7 I tried sending test sounds to spdif out.
8. Tried Daniel_K's support packs.
9. Some of the older drivers used to have other tab with Digital I/O checkbox, but that did not help also.
To add some background information:
My onboard audio is disabled and I have no problems outputting sound to my 2 speakers connected to line on the XFI Xtremegamer. In vista x86? I was able to output simultaneously to both my 2 crappy speakers and to my Onkyo receiver (7.). I saw that some people were able to get stereo output through optical out, but I can get a **bleep** squeak out of my onkyo from XFI.
I don't usually post on the boards, because I am able to come across a solution, but this is the first time in my life that I could find a solution. If it wasn't for the price I paid for XFI, I would probably ditched it already and went with onboard Realtek. The problem is that I know XFI sounds better, besides I already spent the money so it's not very useful outside of my computer.

Jmacguire,? thanks for your advice.
It's a very interesting post, I think it should even become a sticky here as it very nicely describes how Vista passes audio to applications.
Unfortunately, that doesn't fix my problem. I tried setting my speakers to 5., and 7.. I also tried setting spdif as a default audio device, but then I get no sound? at all. ?
I went as far as configuring ffdshow filter to enable spdif pass trough. Since I don't even hear a test sound from windows in my receiver, I think that there is some option somewhere that pretty much disables any output to my flexijack.
Also a funny observation,? when I downloaded an iso image of creative officuial drivers ( from April last year I believe)? I had extra options for digital input/output in speakers tab in control panel and in creative audio console.
It seems weird that creative removed those options from newer drivers.
However, checking the checkbox by enable digital I/O did nothing for my problem.
I begin to wonder what would be the most cost effecti've solution to connect my pc to my receiver. I want to use both my computer speakers and my Onkyo receiver, and by using audio jack splitters I will loose stereo signal (if I am correct) and that's a path I do not want to take, but if flexijack will not work in vista 64, I do not have a choice.

When I plug my headphones into the headphone/optical out jack programs hang

I have an iMac 20 inch LCD. On the back their is a jack with a picture of headphones, but it is also labeled as "optical out". I plug my headphones in and they work. Great. That is not my problem today.
My problem is that whenever I plug the headphones in or unplug them, iTunes (and other apps using audio) hangs and when I try to adjust the volume with the keyboard buttons nothing happens for 15 seconds or more and then the volume changes, not that anything is able to play. If I wait for a minute or so then all my applications start working fine again and I am able to hear my music and adjust the volume.
What in the world is going on?
1.8 Ghz G5 1.25GB RAM Mac OS X (10.3.9)

Thank you. That is good information.
Does this mean that there is nothing I can do about the delay? When I think of a delay, I think of maybe 10 seconds. I am having to wait for a minute or more for my audio to switch. While I wait, I have no audio and any audio program hangs. Is there a setting I can change? It seems rather ridiculous that I have to wait so long just to switch from internal speakers to headphones.
It is like this on other Mac machines? Or it is just my iMac? I hate to compare Mac to Windows, but on Windows or Linux computers the switch is instantaneous.

Weird problem involving my external hard drive - help please!

I recently got a formac mini 120 gb firewire hard drive, which had been working fine with my g4 quicksliver.
i then went to a friends (g5 machine) with my drive and he put some data on it - bought it back to mine and managed to re connect the drive and take the data - no problem - very happy.
I recently gave my drive to another friend using a g5 and when it came back, nothing - i don't get the drive symbol appearing. turned the comp on and off many times and tried re-connecting etc still no drive appearing.
Then i took the drive to my friend with a mac lap top power book. connected there - working fine. Baffling. was happy that my data can still be accessed.
I know it's not the firewire cable because i can get power to the drive - i can see the red light at the fron on.
Can anyone help with this weird problem?
Thanks

Thought you could use this info about getting FireWire to work!
First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 30 minutes. plug it back in and try FW.
If that did'nt work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try. Yours might be the 10.4.10 Combo update. I have no idea since you did not fill out your specs. fully when you signed in to this site. Others reading, download the Combo that applies to your system. This link is for PPC Macs not Intel Macs.
If that still did'nt get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
For those of you with Macs that are not PowerBooks or iBooks, a bad internal battery can cause FireWire to not be recognized, so make sure it's good! Also, here is Apple doc.#88338 on getting FireWire to work.
Good Luck!
Cheers!

No optical-out sound on MSI KT4-Ultra!!

Hi, I have recently set up a system based on the MSI KT4-Ultra board. I'm using an Athlon XP 1700+, a Radeon 9000 video card, and I've installed Windows 98.
Although all the drivers and audio applications which MSI provided installed fine, and 2-channel audio from the on-board sound chip works great both for music and for the 3-4 games I've installed so far, I can't seem to get the optical SPDIF port to work! I bought a cable and connected the computer to my Sony MD-player and attempted to copy my CDs onto MD. I go into the MSI control panel and check the box to enable SPDIF-out, removing the speaker cable from the analog line-out just for good measure. When I plug the optical cable into my MD it recognises digital input and prepares for recording. I press record on the MD and play on the computer's CD-player app, but the MD LED shows "no signal". I'm pretty sure both the MD recorder and cable are OK since I've used them to copy CDs from a Kenwood portable CD-player quite recently, so it must be the MB that's giving me problems. Indeed, when I've stopped playback in the CD-player app and went back into the audio control panel, I found that the SPDIF box had been unchecked of its own accord. I've tried this several times, and I've unplugged the S-bracket and reinstalled it all over again just to make sure it was plugged in properly, and I still get the same problem. All audio works fine except optical out! Haven't got a coaxial cable or recorder so I can't check if the coaxial port is equally buggered or if it's just the optical, but I'm getting really annoyed here: this was the one feature I liked best about this board and the only one which isn't working! Any ideas, anyone?

dude, i think i can get u ur signal, but currently i can only get silent recordings, u may have better luck.
on the minidisc, there should be a switch or button that will toggle synchronised recording on and off, turning it off should get u a signal, but it wont be in sync wiv the cd, ie u cant trust it to form track gaps.
hope that helps, done flame me if it dont, if i manage to get substance to my recording, i will send u the info just in case.
take it easy

Optical out sends constant noise to speakers

Hi,
Is it normal that when I connect the optical out to the surround sound system the speakers produce a constant hissing noise. If I connect any other device with optical out to the surround system instead of the AppleTV, the speakers don't produce this annoying feedback noise. Is this a problem with my specific AppleTV or is this a design malfunction in all AppleTV devices.
The noise always has a constant volume.
I have tried connecting it to a different surround sound system, and the AppleTV
still produces the same noise. It's likely that most people won't be bothered by
this, but I have sensitive ears and I did expect high quality output from this
rather expensive device (given the limitations apple has enforced upon it, even though the hardware is capable of so much more).
Thnx.
(To bad I couldn't get online support from Apple for the AppleTV, seems
they only have e-mail service for iTunes store????)

This is a public update of Lion available since last night.
No a developer thing.
Click in your "Apple" menu (top left) and then "Software Update"
The usual procedure.
I have left my machine on all night long and the sound is still good and the "SoundStay" app is still runnig fine.

Audio Probelms with some DVDS/BLU-RAY discs when using optical out to Audigy 2

I have my PS3 connected to my Audigy 2 ZS soundcard via optical?cable to play 5. sound on my PC sound system (Klipsch Promedia Ultra 5.). I have finally successfully played discrete 5. sound with some DVDs. I have changed my optical out setting to bitstream in the DVD/BD menu (XMB) and selected optical with everything checked in (XMB). So far, The Matrix, The Matrix Reloaded and Minority Report have worked in proper 5. (not stereo matrixing). Both Dolby Digital and DTS tracks (I know it works because it sounds twice as good as Dolby?Digital) ?work in Minority Report. The problem is... Jurassic Park (DTS) and my Blu-ray MIssion Impossible 3 have no audio (probably more too). The STRANGE part is if I fastfoward both films by .5x (so that audio plays in FF) I can hear audio. When FF by .5x the display signal on the top of the screen changes from DTS or DOLBY DIGITAL: Multi Channel to DTS or DOLBY DIGITAL: 5..
What is with that?Also I still do not get audio in any games, Resistance (Blu-ray)?or any game demo but I do get the audio from the game display screen (XMB). Please if anyone has?any?useful advise or information it would be greatly appreciated.
?Thank you!
