I'm hoping someone here can shed some light on a problem I'm having. I'll present the facts as I know them, and let the geniuses here sort them out
I will provide a system profile at the end of this. Recently, the sound cut out altogether on my PC. I'm not sure if this is relevant, but it was following an install of "Crysis". I looked in device manager, and found 3 question marks indicating SM bus controller, and two audio devices. So I updated the drivers on them, and only one worked. I went looking for the other two, and wound up re-installing my ATI Catalyst suite, as well as re-installing the SM bus controllers. This fixed the problem. It worked for a bit, then died on me again. This time, all my settings were intact. I checked the sound control panel, and everything there was fine also, i.e. my wireless headset was the device selected. On a whim, I tried a system restore, and that worked. Now, the sound is out again, and I've repeated all my previous steps, with no solution. I've re-installed all the necessary drivers, tried system restore, checked the sound control panel, but nothing. Everything seems to indicate the sound should be working, I'm not getting any error messages, I've tried a different headset, tried running various apps to see if that was the problem, but I am not getting sound in games, or windows media player, or VLC player, etc...I consulted a friend who's better at this than I, and he suggested that this might be a winXP issue, as he had that problem in the past, but not since upgrading to Vista. What could the problem be ? Why would two different solutions work, then not work ? Here then is my system profile....
WinXP Home SP 3, build 2600
2.50 gigahertz AMD Phenom 9850 Quad-Core processor
FOXCONN A7DA-S/A7DA 1.1 motherboard
2 x 500GB hard drives
ATI Radeon HD 4800 Series graphics card
PS. I also tried disabling the ATI audio driver, to avoid any conflicts it might be having with the Realtek audi driver, but that didn't work either. Any help is appreciated !
