First of all, when the laptop is turned on, it has sound. I can open up his iTunes and play songs, go to volume control and alter the levels. But as soon as I close any applications that deal with sound more than 2-3 times, the mixers will just stop working, even though when I go to device manager, they are still visible with no esclamations or warning signs.
It will continue to have no sound, and volume control won't open up, saying it cannot find any mixers. I've re-installed the driver from the manufacturer for the specific model, but still no improvement. I checked to see if all the settings were correct for the audio, and they were, audio hardware acceleration and all. I even set all defaults back and tried a system restore. NO LUCK.
I would just swipe it, but he has a legal version of Windows and I don't want to have to impede upon that. It's a brand-new laptop, still under warranty. Please, if you have any knowledge pertaining to this, I we would greatly appreciate any insights you can give.
