Computer help forum: Loss of Audio

There is no generic AC'97 driver. One must install their motherboard chipset driver and then the sound driver for the AC'97 implementation that board used.

Sorry to see you omitted machine/board details or I would have tried to supply which 2 drivers I would have tried.

I have no audio on my computer- "No active mixer devices available". " Sound device is not installed". When I go to 'Sounds and Audio Devices' it is 'greyed out' and I cannot change the volume, or 'turn it on'- the same with the sound recorder. I will include the hardware listed, each saying "this device is working properly":
LITE=ON-LTR-483275, Realtek AC'97 Audio, Audio Codecs, Audio Codecs, Legacy Audio Drivers,Media Control Devices, Legacy Video Captive Devices, Video Codecs. Under 'System Properties - Hardware LITE-ON-LTR-483275 IS NOT LISTED, and all the others are, but I don't know how to 'get is listed there'. I have an emachine T2540, Version 2002, Service Pack 2 Intel Celleron R, using Microsoft Windows XP Home Edition and MSN9. I NEED HELP!

I have had that same problem with two of my emachines, one was the same model, and the other a t1800. Im very sorry to say, but there is a good chance your computer is fried. Emachines have a very nastey problem in which their factory power suplies suck and burn out easily. Often when this happens, one of two things happen: the hard disks, and possibly disk drives, are shorted out and fried, or, the mother board gets fried. If your computer is still running, I would highly suggest you get a new power supply before you try running it again, as the loss of audio is a good sign your ps is going out and is already causing damage to the mother board. Being a celeron processor, it wouldn't be too expensive to replace the power supply: 100 bucks at best buy for a 400W, where the original ps runs at 250. This would mostlikly help your computer last longer. I really do believe you have the same problem as me, which could up the cost a little, where you will have to purchase a new motherboard, which can be difficult to find at a store. Your best bet would be online somewhere. These can come at a variety of prices, depending on what you need. I'm sure you can find one for 50 to 80 bucks with just the essantils. It probably wouldnt have more then 2 or 3 ram slots, and would mostlikly only have pci expansion bays, but it would get the job done. If this is the case, make sure the mother board is compatable with your Celeron Processor. Hope this ISN'T your problem, though I have seen this problem with many emachines. If this is, I hope that this helped out.

The way my post reads it looks like I had updated the nVidia driver because I had a problem with my volume, so I just wanted to clear this up now. It was after I had updated the nVidia driver that I had problems with my volume.
