MPC-HC.EXE

Here I've listed various ways to solve your no sound issues in MPC-HC / Media Player Classic

1. Options -> Internal Filters -> Audio Switched -> Disable, Apply and then Re-Enable

2. Options -> Playback -> Output -> Audio Render -> 1: System Default.

(Make sure that playback on your system sound settings, is set to the audio device that you are using)

The solution bellow worked for me, but remember that it may cause additional problems!

3. Open "regedit" via Start Menu by entering regedit in the text field at the bottom, or press "Windows Button + R".Go to "HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\LowRegistry\Audio\PolicyConfig\PropertyStore\" and then Search and remove all folders ending with "_0" that contain mpc-hc.exe, you can do this by pressing ctrl+f after you are in the PropertyStore-folder. Be careful so that you do not remove keys outside of the PropertyStore-folder.

Once all of the keys are gone, you should be able to watch videos with sound again

Thanks to sbalmont for the registry fix.
