Need drivers


This is shooting from the hip since I don't know your operating system. Open the control panel and go to Hardware and Sound. Next, click on sound. You should see a device listed under Playback. If not then you are missing the driver for your sound card. If that is the case you will need to go to PC's manufacturer web site and download the necessary drivers. If this is not the case then you can go back to control panel under Hardware and Sound and under the first item is Device Manager. Open this up and check that there are no devices with a flag. If you do find one with a flag then open that category and select device then right click on it which will give you the option of updating the drivers. Hope this helps.

My speakers are plugged in and connected but there is no sound and it says there is no audio device. how do i fix it


Check that the speakers are powered on (assuming they need power) and that the volume control is set at a mid-level.Next check that you have the speaker 3.5mm jack plug inserted into the correct speaker socket on the audio card - there are normally three sockets, one each for a microphone, speaker or headphone output and for line output - these are often colour coded on newer systems and if so, match the colour of the speaker jack plug to the speaker socket.If the speakers are connected by USB instead of an audio jack plug, then check to see if the USB device has been recognised automatically - if not, then you may need to find any software that came with the speakers and install this before the system will recognise them.Finally, open the system audio controls and check what device is selected for audio output - ensure that this is the same as the speaker device you are wanting to use.One further test, if you have the speakers powered on and they have a standard audio jack, you should hear some feedback sound if you touch the contacts at the end of the jack plug with your fingers.

I have mikomi speakers which worked on old xp pc, new pc with vista and they are not getting recognised


It's probably not the speakers themselves...

Check to see if your sound device is registered normally in Device Manager.

Here is a good flowchart for sound problems.

My desktop pc wont recognise my speakers


Go to the control panel, open device manager, check the sound system. If you have installed a new O.S., then you will need to also install a new sound system. Perhaps it ac audio 97 or some other. Look for yellow exclamation mark or yellow question mark and right click on that and update drivers.
Hope that helps.

My friend just got a computer and he coud'nt download his games onto it and he could'nt get sound, so he installed a sound card which he says the computer recognised,but when he plugged in his speakers and...


PC does not recognise the card, You have to install the driver of the sound card. Right click on my computer and click Property and then click on Hardware and Device manager. If there is a question mark on the sound device than you have to install the sound card driver. A CD that comes with the sound card. Doubel click on the question mark and just read instruction and do installation. Is that answers your Question? Cheers

Have speakers but no sound.computer does not know it has audio port.


Well, they both should work if you go to HP's download and support website and download the appropriate drivers for your associated hardware. Find out what hardware you have by downloading a marvelous freeware program called Belarc advisor. it will list all hardware, software, versions, keys, etc. When you installed the XP frm Siemens, it likely installed drivers compatible with the model it was designed for, rather than your Fujitsu. First, go to control panel, click Hardware and sound, then see what audio device it thinks it has. If it isn't the one your motherboard was designed for, find out what motherboard you have with Belarc, then download the audio device which works with it at the HP website. Whew. Let me know how it goes.

Genius speakers


there may be a very simple solution--first go to control panel, and click on sound. Somewhere there is a place where you configure your laptop sound system; if you click on internal speakers, that's what plays. If you click on external speakers, then your plugin speakers will work. Unless you configure them for use, it won't recognize them.

Speakers are not being recognised


i would like to know if your on board soud or sound card is not being recognized by your system? as far as i know speaker will not work if your sound device driver is not installed. so maybe theres nothing wrong with your speakers. try to go to my computer properties go to system device hardware and see if there is an yellow exclamation in your sound device. if there is, update the driver using the provided cd from your motherboard, if its on board sound device. but if its a sound card, update the driver using the cd provided from your sound card. but if your sound device is ok and there no yellow exclamation, probably you hooked your speaker connector to the wrong jack. it should be the color green one. try and good luck
