Hello members, Today I noticed a problem when I open ishouhdpro. When I open this app while watching youtube I lose sound! No sound at all, unless I deselect the sound option at the top of ishowuhdpro and the the sound comes back. What in the world is causing this!? I opened up system prefs and I noticed that the internal speakers had been deselected! I also noticed the when turn on and off the sound on ishoeuhdpro it would automatically deselect internal speakers in system prefs! Why is this? I have tried every thing and cannot resolve this! Can someone please help? This also applies to watching a vid in quicktime or vlc. I also just noticed that when I made a screen recording with quick time , I have no sound during play back.
