Question about IBM ThinkPad R40 Notebook

1 Answer

Sound card no longer functions?

I seem to have the necessary drivers on my computer, but when I try to open sound programs I am informed that there is no hardware installed. When I look in System Information / Components / Sound Device, there is simply nothing there.
It used to work just fine. I recently went out of town for a spell, packed up my thinkpad into its protective case, returned and found it untouched, but suddenly the sound card is no longer recognized. I even tried reformatting the whole machine with no luck. What can I do? Why would it simply stop working like that?

    system is from when IBM was making these r40s, it was a pretty new machine when I got it.. I'm guessing.. 2003? The problem with that site is that windows doesn't seem to identify any make or model or manufacturer about the soundcard.. I'm trying to find some kind of schematic so that I can feasibly open it up and look myself. thanks for the response, though.

    driver type seems to be legacy audio.
    all drivers and codecs appear to be there and installed and enabled. no hardware shows up, though.
    It is an IBM machine, does Dell offer support?

  • brinesalt Feb 13, 2009

    yes I don't have much experience with computer innards just yet.. I've been taking it apart a little and trying to locate the soundcard, but no luck thus far.
    I have done all such control panel things. nothing will play, nothing will open.. whenever something starts to open I get popups informing me that no device is detected or that no device is installed and I always get back to the same circular troubleshooting things.. I think the card may be fried.

    try the dell website

    if you take laptop to a small repair store usually they will test the audio on the spot at no cost

    maybe card is gone

    have you opened sounds and audio in control panel to see if default settings are correct in audio

check your speaker first..
in your control panel>sound and audio device driver.
or in the leftside of the sidebar, if you can see the speaker icon there click it, and make sure that it is not in mute.

Or maybe your Sound Device was broken.. update your sound device driver
or install your sound driver that is compatible with your motherboard..

Or if your sound device is built in, and not functioning
You need to install a sound card in your motherboard.. it works

Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might...

Click on My Computer, then on the left "View System Information", then click the Hardware tab, then click Device Manager, then Sound category. If there is a yellow question mark next to your Sound Card listing then you either need to update the driver or run the troubleshooter.

What is audio drive

In computing, a device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device.

A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware-dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.

I request you to please send me a link to the driver download for Creative Desktop Speaker Inspire 2.1 2500. My email address is Thanks!

There are NO drivers for any desktop speakers, you only need drivers for your sound card. Your support page states this .....

Creative speakers do not need to be installed at all as they can be plugged in to a device and ready to be used straight away.
Desktop speakers are designed to function with most sound cards without the use of any drivers. As such, there are no drivers necessary for the speakers to function as they were designed. The sound card or audio device which the speakers are plugged into may require drivers and/or software to work. Ensure that your speaker is connected to your sound card's audio out and that your sound card is configured properly to output sound. Please contact the sound card manufacturer for driver availability.

reinstall the sound driver probably have it on the motherboard driver 's cd if the sound card is an on board one...if not just look for the driver cd ...If you do not have it .than you should open and see the manufacturer and name ..than search on google the name of the manufacturer and the word support near it ..and will guide you on the site where the developer has the download support for the the product by name ..and the operation system you use..and download the latest driver for the sound card ..after installing into the computer restart and when you open the player the direct bad sound driver error will be no more and the sound will be on ..
if you know that you didnt uninstall it by mistake or in purpose can even try a system restore..and get to an earlier date when the driver was on and functional..for that just open the all programs from start ..accessories..system tools system restore..
choose to restore to an earlier date ...choose a highlighted date from the tab ..and proceed..If there are no errors this will make it functional..if you choose a date when all was working..

Sound device

Do you still have the MB CD with all the drivers still with you, if so then run that CD once. Secondly soundmax has many versions running so look for the driver that was released during the time you bought your PC. Many a time you got to manually add the hardware and then its driver for it to function properly....................sodeep

Computer not picking up sound card

This is one of 2 or 3 problem... This is usually a driver issue. Either the wrong driver or driver not installed. Less likey is a bad port on the motherboard that the speakers plug in to. Another could be, if the computer came with Windows Vista, which I also do not like, the components could possibly be incompatible. Most likely, you are not finding the proper driver. If is not helping you, you might want to either open the machine to check the brand of the sound card or take the computer back to the place of purchase if recently purchased. If the computer has another slot where the sound card could plug in, try that, just in case it's a bad slot on the motherboard.

Sound device problem

if you go to the start menu and right click my computer on the list at the bottom it says properties click thAt a window will open called system properties on the tab titled hardware at the top click that a window for the hardware will open and you are looking for device manager in the device manager you can update and mess with whatever you have installed on your computer. now look for sound video and game controllers on the left is a plus arrow click the + symbol and it will expand your devices look for anything titled with the words (audio driver) this should give you make and model information of your sound card and drivers from here you can use windows (by double clicking your selection) to troubleshoot and update that driver or what i would reccomend is write that information down and then google search the description for your sound card and driver i think a generic driver is called legacy audio driver or something like that. anyways hope this fix ya

What sound card have you got? you probably unintentionally removed the driver along with the program, you will need to put the driver back on.
