No sound coming out of help Patches (Maxhelp)

Hi there, I am opening some of the help option out of some objects and trying to listen to the patch examples and no sound is coming out. I can see the sound happening graphically but I can´t hear anything. The Audio on/off turns on as orange, wich I understand is because it reproduce the sound from that specific window patch and no others. My own patch works and make sound. Audio settings are correct and worked well until now. What can be the reason of the problem? I am using windows.
