Every since I switched to a KT600-A ECS motherboard from a A7V600 ASUS Motherboard (along with complimentary processor), my sound no longer works!

The system SAYS it's there, and I can play audio files, but no sound emerges from them!

I have tried EVERYTHING! I checked to make sure the speakers work (they do), tested other speakers (don't work either), made sure if things were muted or not, and tried multiple connections for my sound system to make it work. I have updated ALL DRIVERS! Microsoft (Windows XP here), Realtek (Oh! It's an AC97 Realtek sound system!), and motherboard. I even uninstalled-reinstalled the sound system countless time.

Yet, even after all that, it still won't respond. ;.; I just don't know what to do. I'm completely out of options! Please, PLEASE if ANYONE knows what could possibly be the problem, please help!Darkjester...... Have you tried clicking start/run ..... and in the run box type
dxdiag ....... and then enter ...... now click on the sound tabs ( there are several of them ) then click on the test button ....... follow the info on the screen . This may point you in the right direction .

dl65 Okay just tried that. When I opened the program, I saw this error: COuld not get basic sound info: 0x80070057 Invalid arguments. This came up twice.

I did the "Test Directsound" and answered no to the question(s) since I didn't hear anything. however, by doing so, it just went back to the program and nothing else happened. :/ Bad sign?When you switched motherboards did you reload Windows?Reload? How do you mean? I know when I started windows up it asked me to re-verify everything and went through the registration process again. If you mean like, reinstall it, then no. Should I do that?If you have the CD it is ALWAYS a good idea to reload Windows as the hardware is all different from the machine it was originally installed on. Alright... reinstalled windows xp... did everything that I did before over again to make sure... Still nothing. ;.; I'm getting so frustrated by this!!!

I tested dxdiag again and this is the message I got after sound test: Failure at step 19(User verification of hardware): HRESULT = 0x00000000 (error code).Nevermind!!! I fixed the problem. ^^ I don't... want to go into detail about it because it's actually something that was right under my nose and I feel embarrassed about it... thanks though!Darkjester.... there certainly no problem ...more often than not it's something simple ........ but for the sake of someone else with the same issue , it would be appreciated if you would post what had been overlooked .

Glad to hear your back up and running

dl65 Please tell us, I want to sleep tonight.
