Terrible static on output of USB speaker system

Hi,
I have a Sony USB speaker system, it's basically a 5.1 receiver / speaker system which takes input from digital optical, analogue and USB. The USB part when plugged in to a computer presents itself as a soundcard, so when plugged in to my new Leopard Mac Book it appears in the 'Sound' preference pane as an output type.
I get terrible static over all output, I've tried all the usual stuff and nothing is working, I didn't get this problem under 10.4 (however, I was also using a MacBook pro not this Mac Book), I don't get the problem on this machine when I use the digital-optical out rather than the USB.
Anyone know if this is the same issue as associated with Core Audio and some USB mixers?
Anyone got any other suggestions?
Thanks
Adnrew

I also started having problems after last security update when playing Itunes over USB Harman Kardon Speaker system. Static, popping sounds, bending music tracks are the main issues. The distorted sounds have no effect if the internal speakers are used. Apple, please help!

Need help connecting new HDTV to an old 5.1 speaker system

I have an old Creative 5.1 speaker system that I want to connect to my new HDTV, and I am not sure how to do it in a way that preserves the 5.1 surround sound.
My new TV only has two options for audio out:
1. Optical/TOSLINK
2. 3.5 mm jack (labeled "headphones")
My speaker system has three options for input:
1. SPDIF (a single RCA connector)
2. 9-pin DIN
3. 3.5 mm jacks (two of them, labeled "Line In" and "Rear In")
The manual for the speaker system is here:
http://download.cambridgesoundworks....s/DTT2500D.pdf
How do I connect my speaker system to my TV while preserving the 5.1 surround sound?
If I simply connect the TV's headphone output the the speaker system's "Line In", then I won't get 5.1 surround, right -- only stereo?
Is there any way to convert the TV's optical/TOSLINK output to SPDIF (a single RCA connector) or 9-pin DIN?
Thank you for your help!

How to play Mozaic over car radio speaker system without static?

Playing Zen Mozaic over Car?s Radio Speaker system without static?
I just purchased a Zen Mozaic and want to use it primarily for playing books downloaded from the local library over our car?s radio speaker system without static.
I purchased a cheap audio cable to connect the zen to the AUX interface in the car but I understand that trying to play it over the car runs into the problem of bad static.
Is there some device that will allow me to play the Mozaic over the car radio system without static?
Thanks very much.
Bruce? [email protected]

D? Are you simply plugging a jack from the headphone output on the Zen into a headphone-like input on your stereo? That sould work fine, with possibly only slight "whine". If you are wiring into the back of your stereo, it should work just as well unless you have poorly shielded cables or your car has crummy sparkplugs. Do a Google search on this---what you are doing in case 2 is common on motorcycles and they will tell you how to use a resistor circuit to cut down on ignition interference.
You can also either use a cassette adapter (if your stereo has a cassette player) or an FM transmitter (many varieties of these). The FM transmitter works well, but you'll pick up static and interference if you dri've into an area where an actual FM station is using that frequency. You just have to "change channels" on your radio and transmitter in this case---simple. The sound is pretty good (not as good as direct cable or cassette adapter) and is more than adequate for books.

Connectin the 7.1 Speaker system to LCD TV

i recently got a Lg LCD tv (26 inch)....just wanted to know that can i connect the 7.1 speaker system to the and the DVD player and will it give good output......and if not.....whts the solution or the alternative to it

I'm baffled at how you got it to work. I'd be humored to know what kind of loops you must have jumped through to get it going. Humored... and very much interested in the hack.
I brought one home from a Microcenter today for my PPC Mac Mini (10.5.2) particularly.
I've tinkered with it all day but it just is not producing any sound.
The manual instructions do not lead to results.
It does show up as a device by profiler. Alas Audio MIDI Setup is refusing to recognize the FireWave.
So I'm out $100 and am looking at another trip back to return it... unless it CAN really work.
I've emailed Griffin.
Doesn't work on a 10.5.1 Mac Pro either.
I cannot find ANY devices that will do hardware decoding via firewire /or/ usb that are supported by 10.5.2 that aren't total overkill for what I'm using it for. This seemed like a perfect solution, but I'm really dissatisfied that it didn't work out of the box and with the lack of Griffin's support.
So please if you can help me figure this out I'd really be grateful.

Problem connecting 7.1 speaker system to iMac

I purchased creative 7.1 speaker system yesterday (Model No: Inspire:T7900). The package contains a cable to connect iMac and woofer system. The cable has 4 pins to one end and 3 pin to other end. According to the manual, I connected the 4 pins to woofer system with the matching colors. Now the problem is how to connect the other 3 pin end to iMac. iMac does have only one analog out, if I connect any one of the plug, only 2 set of speakers are giving the sound and the output switches from speaker to speaker everytime I change the pin. Is there a way to connect all the 3 pins to mac so that all the 7 speakers will become functional. Please help me... I'm very much worried :(:(

I just got a new iMac. And I wondered if I can. Use my yamaha speaker system with subwoofer?

I just got a new Iimac and I wondered if I can use my speaker system from my last pc, the speakers are yamahas with a powered subwoofer ?

If your presumably "amplified" Yamaha speakers have a USB connection, then it should work fine with your iMac by connecting the USB connection and THEN going into your Mac's Applications folder>System Preferences>Sound>select the "Output" tab and select the Yamaha speakers shown in the list below. That should do it.
Hope this helps

How to install my 5.1 speaker system

Hi,
I'm going to purchase a new 20" iMac once Leopard is out in October, I will be moving from a Windows PC and would like to continue to use my Creative Inspire T6060 5.1 speaker set.
I have noted that the iMac only comes with a headphone jack, currently my speakers connect via three seperate jacks into a soundcard.
What is the best way to connect my speaker system?
Thanks in advance for your help.

Headphone jack on all current Mac models (include latest aluminum iMac) doubles as SPDIF digital optical output as well. In other words, both analog (for headphone/line-out) and digital audio outputs are built into the same combo jack. Same analog/digital implementation for the audio input jack. Alternatively audio output can be sent through USB bus in digital form to external decoder. Thus unlike PC, the compact iMac does have many extra features already built-in.
All you need is an external 5.1 decoder to decode 5.1 digital output from headphone jack or USB port into analog format with three analog outputs for Creative Inspire T6060 5.1 speaker set (woofer/centre, front L/R, surround L/R). The only such decoder I have come across is Tutle Beach's Audio Advantage SRM (www.turtlebeach.com) though there are many surround audio decoders/receivers (mostly with SPDIF optical outputs) on sale in audio equipment shops. Take note that Creative Inspire T6060 is active speaker (amplifier built-in) whereas outputs from some surround decoders/receivers are meant for passive speakers. The difference is between low line level outputs (for active speakers) vs high amplified outputs (for passive speakers).
Optical Toslink cable with two different connectors on both ends (standard Toslink / 3.5mm Mini Plug) is required to connect between headphone jack output and external 5.1 decoder input. In case when USB port is used, any good USB cable built for peripherals (printer, external drive etc) will do.
Since I never play game and hardly watch movies with my new aluminum iMac, only good stereo audio is required for music appreciation with following setup:
iMac USB port -> Firestone Fubar3 DAC -> Firestone Tube Head Pre-amplifier (vacuum tube) -> Harman Kardon SoundStick2 speaker
Hope the information will help.

How to interconnect Creative 7.1 Speaker system to

HI All,?I have bought a Creative 7. Speaker system. I have connected it to my TV using the Audio Out (left & right) to the Auxiliary In of the 7. speaker system and now only 3 speakers are producing the sound. The center and the surround speakers have no output. Please guide me on how I can interconnect this 7. system with my TV and get the speakers working. Thanks in advance.Chris?

--Static problem with inspire p5800 speaker setup--

Hi,
I have recently purchased this speaker system (refurbished) and after hooking it up, I noticed static, a permanent eerie sound that is coming out of the speakers and I dont know how to get rid of this. I have a SB Live card, don't know if it is compatible or not but I get output, its just that the static is present and very annoying. Any suggestions will be appreciated, thanks.

I think it depends on the soundcard, I don't know that model, but maybe it simply isn't able to sense a headphone is plugged in? I know SoundMax chips are able to, and Sound Blaster probably are too, but I can't seem to find that piece of information on realtek's site... So (please other users, correct me if I'm wrong!!?) I'm afraid you are just going to have to learn to live with muting center, LFE/Sub and surround channels when using headphones...
EDIT: I think the headphone jack will still work if you switch the set off, would be easier than resetting all volumelevels everytime you are done using the headphones.

My usb speaker will not install

I have a mac mini and the internal speakers still work, but are soft in volume. Just bought a usb speaker that will not install. What next?

The internal speaker of your Mini (it has only one) isn't that loud, but you can change the volume by using the volume-control keys on your keyboard or by going to System Preferences->Sound.
There shouldn't be anything to "install" to get a USB speaker to work. Just to to System Preferences->Sound->Output and choose to use that speaker as the destination for your audio output.

5.1 Speaker system on MacBook

Hi everyone
I've just bought a 5.1 Esc XCite surround speaker system, which I've connected to my MacBook using a TOSLINK cable and a mini adapter. If I put a 5.1 DVD in the drive then I'm definitely getting wonderful 5.1 audio out - great! I can also play stereo CDs and get the usual OS X sound effects.
So here's my question. What should I see when I use Audio Midi Setup to examine the audio output device? I expected that when I select Audio Output and click on Configure speakers that I should be able to select a 5.1 speaker set up. But I can't. It stays on Stereo. What's going on? Have I missed something? This is important to me because I'm developing an Audio Unit based on the Core Audio 3D mixer and I need to have the correct speaker configuration set up.
Thanks
Bob

I've found the reason for the problem: the optical output port can only output 5.1 surround information if the data is encoded in Dolby DTS/AC3 or Pro-logic; otherwise the port can only handle stereo. Most DVDs contain Dolby surround sound data which the optical port transmits directly. The decoder built into the speaker system decodes the Dolby signals and produces the 5.1 sound. Hence DVDs play beautifully using the optical port. Sadly, Core Audio does not seem to include an appropriate codec to convert arbitrary 5.1 audio into DTS/AC3 data.
To get a true 5.1 system, I need to buy a Firewire/USB sound card with individual feeds to each speaker. I have a Firewave on order and I'll report how it works. Unfortunately, the Esc Xcite system doesn't have individual speaker inputs, so it can't be connected to the new sound card but I've sold it on to a friend who's very pleased with it. Of course, I now need to buy a new speaker system, but at least I know what to look for.
Watch this space for updates.

DV-5 1192eo 5.1 speaker systems

Does my HP Pavilion DV-5 1192eo support 5.1 analog speaker systems?
Please advice.
Thanks

is there such a thing? I checked the Apple store, but didn't see anything.
The iMac headphone output is a "combo jack" that can accept either a 3.5 mm
analog stereo plug (2 channels only) or a 3.5 mm S/PDIF digital optical plug.
The digital optical output supports both 2-channel PCM and 5.1 Dolby Digital.
So, it would be possible to feed your speakers from the iMac's digital optical
output -- but you'd need an external decoder to convert the optical signal to
the set of 5.1 analog signals required by your speakers. Someone probably
makes a stand-alone optical-to-5.1 decoder, but I'm not familiar with any.
Since you'll need an external decoder box in any case, it might be better to
look for a USB or Firewire-based 5.1 decoder -- such as Griffin's FireWave:

That has the advantage of not blocking access to the headphone output.

Creative I-Trigue L3450 Speaker System

Hi.
I am interested in the above product but was just wondeirng if anybody could answer some questions for me.
Is it possible to plug a USB MP3 player into the controller of this system and have the music played? The following link seems to suggest that a USB MP3 player can be plugged in:
http://www.boysstuff.co.uk/product.a...id=&src=Search (st picture)
Can Anybody confirm this?
Also, must this system be connected to a PC or can it simple be plugged into the mains and have MP3 players etc run off it's
Any help would be brilliant!
Thanks!

badboyuk,
The USB port on the volume control is what we call a M-PORT. Basically, it does what you mention by it's only compatible with M-PORT compatible player and as far as I know, only the Creative MuVo NX is supported. The speaker doesn't need to be connected to the computer only. You can connect to any audio source that's using a 3.5mm stereo minijack output.
You can also download the user guide for this speaker from the Product Documentation page for more information regarding the speaker system.

A solution to the S750 speaker system problem

Well my s750 died just like everybody elses. But after creative wanted me to pay 75% of my purchase price, I found a better solution. Nope, I am not fixing the unit like you guy's. I do not see the need to fix a poorly design system! I am not sure if creative or indigo/bash/blade audio is to be blamed. But if I had to pick, I would say "indigo/bash/blade audio". Years ago before blade audio became indigo, I had a chance to visit their location in ontario Canada. This was just when they stop making the blade audio car amps.
While I was there, I happened to see this long list of brand names they had started to make amp modules for. Names like Harman International, Klipsch and so on. Anyway I cast the blame on indigo for this reason: Some years ago I had purchased a set of "harman international" infinity IL series speakers. Like our creative s750, the infinity shares a bash powered subwoofer system. And just like the s750 the infinity subwoofer like to blow up too! In the case of the infinity, the power supply was the weak link. The amp module in the infinity at that time, was built just like the blade audio car amps before. Which in my opinion is a much better design than what is being used in the s750. I remember one of the sale guy at circuit city at the time saying, "I wish we would drop this model". He went on to tell me the failure on the powered units were very high. You know there is a problem when the mid level Creative Inspire T7700 7.1, out last the flagship s750. Now, whats my better solution you guy's want to know? Two words , Simplifi Digital! The 7075a 7.1 amplifier along with Definitive Technology Pro Sub1000 and the remaing surround speakers from my s750 system. Yes, it did cost me more to go this route. But what I now have is a much more reliable system. And a sound that the s750 can only dream about. My s750 died while I was listening to Dave Bruebeck quartet "take five" at mid volume. With my current setup, I can listen mid volume all day long with no hiccups.
For those who my have the cash to spend. I recommend looking at my direction!? Keep this in mind, make sure whatever powered subwoofer you choose, is adjustable up to 50hz. The creative surround speakers dont play very well below 20hz. Also make sure whatever powered sub you choose don't use a BASH amplifier. For those looking at the s750 as a purchase, good luck. Or go over to partsexpress.com and get the Dayton Part Number 300-670, surround speakers. Then get the simplifi digital 7075 7.1 amplifier and power subwoofer of your choice and make a better/best system. Sorry Creative Labs! This post is NOT intended to cast negativity. I use and like the products you offer. I just do not like the s750, and the reasons are all over this forum and elsewhere on the net. I currently own 3 audigy 2zs sound cards, three Inspire t7700 speaker system, three sound blasters modems and yes, one defective/dead s750 speaker system. If anything use this post as a positive to what Creative Labs could offer in the future. A system like I now have, sure would be nice with the Creative name all over it.
