Page 10 - No audio device???

Have you tried disconnecting the mixer/amplifier? It's the easiest way to try to see if they have anything to do with the problem.

Thanks for the comment but unfortunately i try finger crossed but it did not worked out.
The strange seens is that i ve seen once my audio device having a problem in the device manager, but now it just disappeared.

i have a dell inspiron 1501 and when i try to play my music it comes up that i either have no audio device installed or its being used by another program. i know its not being used by another program because i onl have one installed to play music. when i went in to check my audio devices it said that everything was working properly so i went into the sound video and games screen on my control panel and this is all i saw:
Audio codec
Legacy audio drivers
Legacy Video capture devices
Media controll devices
Unimodem Half-duplex Audio device
Video codecs

i have tried restoring my network settings and it didnt work any suggestions would be much appriciated.

Few things to try:

1) Reboot your computer if you have not already done so.

2) Uninstall your sound card and then reinstall it.

3) Open up Sound (or Audio) Properties to verify the correct hardware is selected. You can open up Sound from Control Panel.

I've got an
Intel Core 2Quad Q9400
Asus P5ql-e (with integrated Realtek ALC1200, 8 channel High Definition Audio Codec)
Nvidia 9600 GT

With Windows XP SP2

After installing XP Sp2 i installed previously the UAA (kb888111xpsp2.exe) and after that the Drivers Downloaded from Asustek website, still it wasn't working. (It says the device is working correctly but no sound is coming out...)
i installed the new driver release 2.81 R2.30 from realtek website but still nothing worked.

That did the trick! I was able to find out what motherboard I am using, and download the appropriate audio drivers from the manufacturer's website.

I have a POS PC Laptop.
I clicked disable speaker sound in the control panels sound options; and it deleted the whole speaker.
Now I don't know how to re-enable it to get sound out of my speaker again.

Someone was saying I had to reinstall driver devices; however, PC Laptops has nothing on their site.

Any suggestions?
