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.

Hi,

This sounds normal for a program like ishouhdpro - it wants to capture sound with the video so it redirects the sound through Soundflower, an extension that passes audio between programs, rather than your internal speakers.

ishouhdpro sets the sound output to Soundflower and then records the sound input from Soundflower, setting up a loop to record audio, although you won't be able to hear the sound yourself.

I don't use ishouhdpro, but I would imagine if you quit the app it will put your output back to internal speakers and the videos captured with it will playback with the recorded sound.

If you are wanting to record video / system sounds in screen captures in Quicktime X:

Go to system preferences, select sound, select the output tab and change it to Soundflower (2ch). Go to Quicktime X, select new screen recording, select the triangle to the right of the record button. It will bring up a menu with "Microphone" at the top. Change the microphone to Soundflower (2ch). Now record the movie. You wont hear any sound because it is being routed from the system, through soundflower and into Quicktime X.

Change your system output back to Internal Speakers and then playback the movie and you should hear all the original video / system sounds along with the screen capture.

Hope this helps.
 
I never had this problem before. In the past, I would open ishowuhdpro and I would still hear the sound, but as of friday this problem started to happen. I now could simply play a Youtube vid, open ishowuhd pro and the sound would cut off. Never has this happened before. Something is wrong somewhere, its effecting quicktime and screenium also.
