I need a power supply/ volume , and bass control for creativbe labs t2900 speakers. can I purchase one?

For the most part volume is controlled on computer, though speakers may have separate volume \ bass \ treble controls. Or, are you looking to purchase?

if your computer came with a motherboard disc the sound drivers could be on it
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question exclamation mark? ! or a red X Right click to reinstall drivers if you dont have a motherboard disk you will need to download the sound drivers
click start control panel sounds and audio,volume,advanced,speakers make sure you have selected the
(((appropriate speakers))) also audio you will find 3 drop down lists make sure you have the correct settings there
also
click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it
if his does not fix the problem
click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar for any further volume control settings you will need to right click on the volume icon system select adjust volume

click start control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
if you need more help with this posta reply
hope this helps

Id try to find another power supply to plug into them with the same voltage. Usually 9-12 volts. Walmart,radio shack, or kmart have universal power supplies you can purchase to test them. Maybe keep the receipt and return it on the chance that it still doesnt work(in which case you'll need a new set of speakers).

good evening sir, i have 2.1 subwoofer computer speakers. it was not working . i replaced ic ic no is tda 8510j even same problem. please help me

The speakers inside desktop computers (if it has one) are very small and do not produce a reasonable volume.
I suggest you purchase a powered stereo speakers and connect it to the audio out connector on the desktop computer. Powered speakers have better sound quality and adjustable volume controls as well as bass and treble controls.

navigate to control panel, select sound and audio devices. select advanced the volume control appears then set the balance to be at the center the on the other advanced option, select desktop stereo speakers. thanks.

Creative used to sell the replacement volume controls on there site but I guess they stopped selling them.

So what I would do is select your product at http://support.creative.com/

Then click on Contact Us

Next click on My problem is not listed

This will get you to email support. Send them an email stating that you need a replacement volume control and powersupply. They will ether refer you to Customer Service or to the RMA department to get a replacement.

Let me know if you have any more problems or questions
