Audio expert help required

This is driving me insane. During many different games I get the random pop-up "window audio device graph isolation has stopped working" and I need to restart my computer to get audio again and it becomes an annoying hassle. I have looked EVERYWHERE on the net for answers but I cannot find anything. I have tried updating drivers and using different drivers.

I have SoundMax integrated audio; before i was using updated soundMax drivers, i got the error. Now im using Microsoft dirvers and i still get the error. Sometimes i can go hours without the error or sometimes only 20 minutes. I am using Vista-64 bit. Or at least does someone know a command I could use in task manager to restart it so I dont need to reboot my pc? Thanks anyways:)

You can shut it down through task manager. Click on the processes tab, find the driver, right click and select "end process". I don't think you can restart it that way. Most hardware drivers get loaded while Windows is loading.

If you don't want to deal with external equipemnt there are internal X-Fi cards you can choose from. If you do decide to go with an new sound hardware be sure to turn off the integrated sound through BIOS.

A good, simple, soundcard should pretty much cost less than $50 bucks.

Just get an X-Fi Xtreme Audio or something.
