No sound from media player

[mranon]

So I've had this problem for a long time and it's just annoying, I'm running on a Dell XPS 15 on a Windows 7 64 bit OS. Before updating my sound driver (HD Realtek audio), I had to turn off audio enhancements to get any sound from VLC or said media player, however there is a huge drop in sound quality, so I kind of neglected it and went on with having poor sound quality. Well I just now updated my driver and though I get sound through websites and sound from my games (Diablo 3, CS:GO, etc.) I still don't receive sound from VLC, ITunes or any other media player. I'm not sure what to do because the drop in sound quality has started to annoy me so I don't want to turn off the audio enhancements.

Go to control panel>Hardware and sound>Adjust system volume. Then open up itunes and or whatever else will not work, and make sure you see it under the system volume tab as raised. Also check any other Ex: Applications.
Now if that is fine, Go back to hardware and sound but instead click manage audio devices check and just to make sure that the speakers are working fine.
Next for VLC try this All programs > VideoLAN > Reset VLC media player preferences and cache files to reset settings, see if this fixes VLC's no sound.
For windows media player try this Start>Run>msdt.exe -id WindowsMediaPlayerConfigurationDiagnostic
Follow the guidelines within the troubleshooting window to see if it fixes your problem.
