Reinstall WinAmp. Check for all of your sound drivers and update old ones.

it didn't work
for each driver i try to update it says that there was not a better driver than the one i have already installed

try to update the driver....check at the control panel.....

Error code 8007057 leads to

E_INVALIDARG...80070057......One or more arguments are not valid error

So there may not be any valid resolution. Try to uninstall the sound drivers in safe mode and then reinstall.

well how do i reinstall
how do i make sure that it won't get worse if i uninstall it
