Megaworks THX 250D - problem with SPDIF?

Hello everybody, I hope someone can shed some light on a strange phenomenon I'm experiencing with my Megaworks THX 250D speaker system. When connected to my computer using SPDIF, the speakers produce a short, loud "cracking" sound everytime any audio playback is started. After that everything works just fine, but when you're clicking through some folders in your file explorer, every click generates a windows system sound and thereby a loud "crack".When I use the normal analog audio jack, everything works as expected. My computer is based on a Gigabyte GA-P35-DS4 mainboard (Rev .) which has a Realtek audio chipset onboard (Realtek ALC889A codec, High Definition Audio). The latest Realtek driver is installed (Version 6.0..5497). Any idea would be appreciated.

The Megaworks THX 250Ds don't support Dolby Digital input. They're extremely good analogue speakers. The SPDIF output mode is for receviers or speakers which support compressed (lossy) audio decoding.
There would be no point in using SPDIF unless you were connecting to a home theatre receiver or a speaker system with digital input.
What you're experiencing is normal for analogue speakers. As for quality improvements with digital connections, that's debatable though it does depend on your soundcard.

Audigy 2 problems with spdif out not working and cracking appear

Hello everyone,
I am new in this forum but after searching through it i decided to post as i din't find a problem exactly similar to mine.
I have a Creative audigy 2 ZS plugged on my computer with this configuration : Gygabyte P35 DS3, Quad core Q6600, Kingston 2 gb.
From the beginning of my purchase i did not have any problem of cracking or connection problems in spdif with digital din in either XP or Vista. Last week end i decided to re install XP after a virus infection with XP SWEET wich install directly the drivers of my peripherals like the audigy.
The audigy is connected to my speakers : Creative? 5. kit 5700 via the digital din connection and without any analog connection as i selected digital out only in my settings.
Everything was working fine until 2 days ago when? while watching a divx the sound stopped working. i checked everything in m connection and everything was good as well as my speakers. finally i connected the audigy via analog cables to the speakers to find that, if i select digital out only no sound could be heard and finally that poping and cracking sounds started to appear.
I don't know what happened with my system as it never did that before in any of my configurations.
When i reboot my computer, the digital out start working again to finally stop 5 minutes later.
If somebody can help me is help would be most welcome.
Thank you!

Well, I do not know much about the red light thingy, but if the S-Bracket works well, it should be not problem, unless you can't get anything from the S-Bracket.

I hope that someone can help me :-D
My configuration:

Problem with SPDIF

Hello All,
I have Creative Sound Blaster X-Fi XtremeGamer Fatalty Pro Series and Digital I/O module on my Windows Vista 32 bit machine. I have connected my speakers using 3 analog outputs of the sound card and they are working great and I am able to hear exact 5. sound, when I play 5. DVDs from Power DVD player.
Now, I have connected my external DVD player optical output to SPDIF input on I/O module. now, I am getting only front L/R speakers, instead of 5.. My DVD has 5. sound, but I am able to get only 2 channels.
Please let me know, what configuration I have to use to get 5..
Thanks

I connect my Audigu with reci'ver Pioneer AX5 through spdif and set "5. mode" and "digital output only". When I start test I hear only front right and front left. Question: why I'm not hear other channels (center and surround back).
P.S

Megaworks THX 2.1 250D with Playstaion 3

Hi guys
I'm thinking of buying a PS3 (the 40Gb version) and running it on my monitor and external speaker system.
My speaker setup is the "Cambridge Soundworks Megaworks THX 2.1 250D" which has a Digital SPDIF (RCA) input, where as the PS3 outputs in Optical TOSLINK.
I'm quite the noob when it comes to this kind of stuff so i'd like to know if this setup would work and what i would need to buy in-order to get it working.
Many many thanks!

el_salvad,
If headset works fine with the soundcard, it sounds like the speaker is faulty. Have you try testing the speaker on another audio source or your other computer that's loaded with the Sound Blaster Live card.

Creative MegaWorks THX 2.1 250D

I have recently purchased a Creative MegaWorks THX 2.1 250D but when I connected it to a computer I had heard a hisss noise from the satellites. I have also creative sound blaster live 24bit. I want to get rid of that noise which is very anoing so please help.

MrHenderson , hissing from speakers is coming only when they are turned ON and no matter how u set volume , bass , treble or push MUTE button hissing is always there with the same intensity.When i connect headphones to speakers remote control hiss is gone (in headphones).Also i connect each individual satellite speaker to portable CD player and there`s no sign of a hiss , just like it`s supposed to be. I agree that "normal" hissing is presented in every audio system but u can hear it only when your ear is very close to speaker.Hissing coming from MegaWorks i can hear from 10 meters , now imagine sitting in front of a computer.Like i said , my first set of MegaWorks didn`t have that hissing at all , just normal hiss which u can`t hear sitting in front of a computer.First set was OK (until they burned) and i paid for them 290$ , when i get replacement for new set price was 90$!That is quite significant price drop which leads me to conclusion that CREATIVE start using cheaper meterials and components for building MegaWorks 250D. I think the first series of MegaWorks 250D was better quality.Harvey got a second set with the same hissing problem , that just confirms it. Harvey, i agree with everything you said. MrHenderson i agree about that running-in but i think this is reserved for Hi-Fi systems over .1000$ price.My first MegaWorks 250D sounded the same from the first day.Sometimes i was listening music with volume set to MAX and didn`t have any problems. I was always cautioned to not add to much bass which will cause distortion because we all now how loud this speakers can play.After 0- months of use they burned out. But when it comes to for some reason amplifier overload or overheating souldnt the amplifier have some kinda overload-overheating protection?
Now , all i need is another replacement with new set of MegaWorks 250D with the same hissing problem like Harvey!

XFI: Problems with channelrouting after THX Se

Hi, i?ve got a problem with XFi, hope somebody can help.
Hardware:
XFi Fatality, Asus A8N SLI Premium Board (Bios .0), Win XP prof., 2 GB RAM, all the latest Patches and Drivers for all Hard- and Software. System runs great without any problems.
A 7. Soundsystem (Teufel Concept G) ist correctly connected to XFi, and works fine so far, but:
i always get problems AFTER i call up the THX Console in XFi Driver/Software, or sometimes just by changing the XFi Modus (Games, Audio...) without calling up THX Console, just by switching the Modus.
Problem is: some soundchannels / speakers are incorrectly routed then. For example, after calling up THX, Front right Speaker is no longer front right, but Center instead, Sub works no more, but subfrequencys are routed then to left side Speaker, and stuff like this. This can easily be checked by "Channel/Noise" Speakertest in XFi Software.
Sometimes some Speakerchannels even fail without any operation or switching to THX or other Modus.
When this problem appears, and i choose "Standard" Button in Mainscreen XFi Software (Xfi Harware is resetted), false routing is over, everything is OK again. I took me hours and hours to find out, first i thought cableconnections or other hardwareproblems were responsible, but that was never the problem.
Anyone else with same problem? Any ideas?

Sorry, but the note is in Spain (I guess), can you please translate?
We have the same issue on our productive HR system - but not on the development system, what makes it curious.

Problem with Megaworks 510D Sub

I have the Megaworks 50D speakers and the problem is at a normal listening volume the subwoofer does not work and the sound has a slight static noise in it. The static noise accompanies the sound coming through the speakers. When there is no sound there is no static noise. When I turn the volume up or just the bass up, the subwoofer comes on and the static noise goes away. At the normal volume level, sometimes the sub will come on if its a bassy song or bassy sounds but its intermittent. If there is not much bass material then the sub does not work at all. When I say "come on" I don't mean that the sub's power light comes on in the back. That light is always on.
The sub has a separate level knob on it and when I adjust it the sub comes in and out randomly. I think this is a separate problem with the knob though.
Could these two problems really be the same problem (with the sub knob)?
Please help.Message Edited by Zertman on 01-24-2008 12:49 PM

You most likely have the same problem that i have. it isnt a problem with the sub. the bash amp or some part of it inside the sub box is starting to break or is broken. The sound will sound different coming through the sats and the sub, since the sub only plays lower frequencies..but im pretty sure it is the same squeal type noise that comes out of both... whichever channel has the loudest volume in the music/game/movie content will have the squealing sound.
try turning your sub up higher and the whole system volume up high.... all speakers should make the sound if played at high volume.. i fixed the problem by opening up the sub and poking around at the various capacitors and things... and it was fixed for two weeks. then it went bad again.
the speakers sound great when played quietly though! its still usable..just only at very low volume levels. oh well.. i bought a logitech z5500 system to replace it.. and just pluged the megaworks sats into it instead of the logitech speakers. seems to work ok..but i wish the z5500 had the "treble defeat" switch on it like the z50. i also wish the z5500 sub sounded as musical as the 50D sub. oh well at least it shakes the house down.

Problem with logitech Z-5500 with Creative X-Fi when connecting SPDIF

Hi all,
I just purched Logitech Z-5500 speakers and Creative X-FI Titanium and plugged it using SPDIF connection (optical).
I configured everything in my computer to work with SPDIF but still i see in the Z-5500 monitor that it's "Stereo" and i cannot hear DST or surround. The rear speakers do not work!
how should i configure it's
In my previous Realtek audio card i had an option for "speaker fill" and then i got good surround (but not with optical connection).
