Today I can't listen to a song on youtube( haven't tried a CD or DVD) clicked on Creative Diagnostics and restored defaults, nothing. I tried to adjust the system volume it said I had no driver installed, all was greyed out and the volume (which was set to zero) would not adjust.
Ran full diagnostics and it failed on MIDI,Wave,Mixer,DirSound3d and mix checks. I tried to run the 'fix' but it said wave driver in use close all apps. and retry.they were closed.
