Question about Audio Players & Recorders

The mysterious motherboard

Dear crayzeetrayn, this ecs M925 still won't take the sound driver, and the real model name is still a mysterious. I only got a new clue which is its socket number: FC 478. On the other hand I have another situation: I have this tower that is dead, I mean dead; I have reseated everything, I got a brand new power supply, but is still dead.
So I got two questions: How can I determine if the power sopply is ok, since it doesn't show any voltage unless the computer is running?
How can I determine if the motherboard is fried?
There was a little shortcircuit on the port of the keyboard because one of the pins was bended, but the computer was working after that until suddenly it didn't want to start, and then it died.

Thank you so much for your concern and your time.

    Dear crayzeetrayn, I did the test of the switch, and that was not the problem; I heard that a capacitor on the board may blow in a situation like this, however, apparently I don't see this; I only see one that is a little bit open on the top, but no signs of any liquids coming out of it. What you say about the keyboard port causing trouble is absolutely true. That was what happened here.

    And no, this is a different motherboard, a newer one, which I'm going to regret to lose.

    Yes, it is, and this thing is now giving me trouble to start up; when the windows logo appears and tries to start it won't complete; in goes back to initialization. The system battery is dead, does that have to do with this?

  • alberts18 Jan 09, 2009

    Crayzeetrayn, I have good news, and very important info for you and others: On the ecs M925 I finally was able to fix the sound problem by installing a new pack of windows xp proffesional with sp 2, and all utilities included. It might be that sp3 is not compatible with old systems. On the other one, the board I thought it was burned out, here is what I did: I removed the cmos battery and the memory sticks, and then I pressed the start botton, and came back to life!!! It took me time to adjust everything, but actually it is working just fine. My conclusion is: there was some kind of trouble (almost damage) on the hard disk and on the memory sticks or sockets. The hard disk used to squeal when I tried to start the computer.

You could possibly have a problem with the switch on the actual case. What you can try to prove this is trace to the motherboard fro the front panel the wires for the switch. Remove the connection off the motherboard and using a small flat screwdriver "short" the connection for those 2 pins. If the system then starts up you know you have a bad switch.

On another note the keyboard port could have caused the board to suffer "damage". I have experieced (25 years of this) keyboards stopping a system from booting. They would power up but never get to POST.

Is this motherboard the same that we are working on for the sound driver?

    Yeah if you see a capacitor that is "open" as you describe .. you cannot rely on that board .. more will happen ..

    I don't recall but did we make sure that the BIOS (on the original sound problem) motherboard has the sound component enabled?

  • Jay Glendenning
    Jay Glendenning Dec 23, 2008

    Yes .. CMOS battery needs to be "good" ..

    Actually .. your windows that was on the machine may have been corrupted that it didn't let you get the sound to work .. no way .. no how .. I had a client with just the opposite problem ... sound stopped working .. tried drivers .. uninstalling .. reinstalling .. you know the drill and well .. lets try putting SP3 on . and viola .. sound worked .. go figure .. so sometimes new is better .. but not always

Audio bus driver failed

You need the drivers for your sound card.

If your computer came pre-built and has a model number, google drivers for this computer and install the sound drivers.

If your computer doesn't have a model number, you'll need to open up the case. Once open, if you have a discrete sound card (it's a card that fits into a slot on the motherboard) you'll need to google the make and model of it and find drivers. If you don't have a discrete card, you'll need to google make and model of the motherboard and find drivers that way.

hello waiyasin, this altec lancing don't need a driver, it just plug and play hardware. if there is a problem with the driver, try to install sound driver from your motherboard driver. if u use external sound card, try to install sound driver from the sound card driver. if u have problem how to install the driver then u just need open the device manager. u can find it on control panel. once u open the device manager window, insert motherboard driver (or sound card driver if u use external driver) into CD Rom. in device manager window u will find sound or audio device, right click it and choose update driver then follow the instruction. that's it.
hope this useful, regards.
NB: if u don't have motherboard (or sound card driver) try to goggling it or reply this solution with your motherboard name (or sound card name), maybe i can help to find your driver.

No sound, how can i put the wires wrong ?

Hi, friends,
First you should roll back the driver ,if the you will face the same problem.
do the steep>

Speakers not workingCheck the following,
  • Speakers, connecting cables and Sound Card are working fine by connecting to another computer.
  • Speaker Cable is connected to an audio port (Audio/Video port in system box).
  • Volume is MUTE / Low (in Volume Controller).
  • Audio drivers have installed.
To Check follow the Steps:
• Go to Start>
• Control panel>
• Double click on "System" Icon> (it shows the System PropertiesWindow)
• Select "Hardware" Tab>
• Select "Device Manager" Tab> (it shows the Device Manager Window)
• Select "Sound, video and game controllers">
• Expand "+" symbol> (check the audio Codes, Legacy Audio Drivers andothers are not in Questioned Mark (?) symbol with yellow color. If there needto install the drivers ).
  • If not, insert the motherboard CD, browse>select audio driver>install. After completion, restart computer and check.

Then, if you know what audio drivers youneed, you can simply download them off the internet. (No need of themotherboard CD these days ;-) )
Simply Google the make and model of your motherboard and say audio drivers. Itshould take you to the site where you can find the Audio Drivers.
For example, the make and model of your motherboard is something like Gigabyte100X, search Google for "Gigabyte 100X audio drivers".
Maybe I can help if you can tell me what is written after the TriangularWarning Sign i.e. the name of the device that needs attention (and whosedrivers are not installed).
Or Right click on "My Computer" and then selectManage.
Go to Device Manager and if you see any yellow warnings there, surely the audiodrivers are not installed and then you can follow the instructions on thescreen.

Hope it will help you.

My computer said I have no sound device. I have the speakers plugged in correctly and have used them on my other pc (so I know they work) But I cannot get them to function properly on the pc I am currently...

"sound device" means the hardware built into your computer that generates the sound. Speakers provide the audible output.
You need to install appropriate sound drivers for your computer model; you have to establish the make and model of your computer (if it's a laptop or a brand-name machine), or make and model of the motherboard (if it's a standard desktop machine). Then you have to go to that manufacturer's website, search for your exact model, download and install audio drivers.

I have no sound can you help on this


You never mentioned if you are using a built in on your motherboard or a sound card hardware...

Anyways... If you are using a built in sound card, make sure it is enable on your CMOS/BIOS setup.. And you have installed the right driver for your sound card from the cd driver of your motherboard...

And if you are using a pci sound card, please check if its properly seated on the motherboard (better if you disconnect the sound card from the motherboard... clean its contact point... and insert it properly on the motherboard)...See the model of your sound card... download the latest driver from the internet and install it.
If this still did not work, better check on the device manager if the sound card is properly installed, if its not it should have a yellow question mark attached to the sound/multimedia devices..

You can also check if windows xp keeps on detecting windows compatible sound first, shutdown your computer.. disconnect your sound card from the motherboard...turn on computer..Right click on My Computer and click properties...Select Hardware and click Device Manager...on the View menu click devices by type...double click the "sound, video and game controllers"....if you don't see from the list the model of your sound card, then try disabling or uninstalling the listed audi driver and or multimedia devices..shutdown your computer..

Now connect your sound card to your motherboard.. turn on the computer..System will detect and add new hardware for your sound card.... install the driver... restart your computer and hear if it makes a log on sounds..

Hope this instruction help you.

Much appreciated if you rate this solution.. thanks..

Need drivers

It is not the speakers you need drivers for but the computer sound chip. Check out the motherboard makers website and download the driver for your particular motherboard. reboot and they should work OK. If not they are probably faulty

New speakers not working computer says no audio installed

Hi, you should install the audio driver for your new speakers to work. If you don't know where you can find the driver, drop me a comment and post the manufacturer and model name of your motherboard or sound card so I can assist you further. And also the Operating you are using now. Your computer says "No audio installed" because it is looking for the audio driver for your sound card.

The make and model of the MOBO (motherboard) if the sound is onboard then you just go to the motherboard maker with your model of the system board and download the drivers for it. Example: MSI NEO-V II then you would just look for that model and get the one that works with XP in your case. If you're not sure of what you have turn off and plug the cord for the unit and open and see what you have. If you're using a laptop then you need to go into the bios and see what mobo you have.

Speakers not working

What you need to do is install new sound drivers, now depending on how your system is set up there are a couple possible solutions. Now I will walk you through a couple steps but before I begin I want you to remember something for me and I will explaine in further detail later. BEFORE INSTALLING NEW AUDIO DRIVERS YOU MUST FIRST UN-INSTALL ANY DRIVERS THAT ARE CURRENTLY INSTALLED. That is very important as if this step is skipped the problem will still exist.
1st solution go into your control panal, find the icon for your sound options, double click on that icon. Go into the properties and uninstall all audio drivers. Then make sure your P.C. is connected to the internet and restart your computer. When the P.C. restarts it will look for driver for your audio device, it will also look online to try to find drivers. This should fix your problem, just follow the instructions and install your new driver. However for the sake of giving you a wider set of tools I will list a couple other options.
2nd solution check Windows update, let them scan your system and see if they have an updated audio driver. If they do then un-install any current audio drivers and run the update.
3rd solution if you have an onboard sound card (it is sodderd to the motherboard and canot be removed) You may have to go to the website of the manafactuer of your motherboard and enter the model number of your motherboard, they should have instructions for updating the audio drivers for your sound card. You may have to find the support section of their website .
4th solution If you have a PCI video card (it slides into a PCI slot on your motherboard and can be removed from the computer) You will have to find the manufacture of the sound card, sometimes the easiest way to get this info is to open the side of your computer (remember to power off and unplug your computer before removing the side) and looking at the card its self as most manfacutuers will have their name on the card, take note you may also need a model number off of the card for some of the manufactuers. Find the website for your videocard and try to find drivers for your particular card, keep in mind again these companies make many diffrent models so there may be diffrent drivers for diffrent video cards and even drivers based on the operating system you are using. Once you find the driver you need make sure you have un-installed any drivers that were on your computer and download and install your new drivers.
Hope this helps
