Checking Sound Installation


Can't hear anything when trying to record app-audio?

Please check the following:

note: applies to iShowU Instant and iShowU Studio 2

1 - Get up to Date!

First things first, make sure you are running the latest version of iShowU. Visit: to get the latest. 

2 - Verify iShowU Audio Capture Driver

What we're going to do here is make sure all channels of the audio driver have their volume set, and don't have a rogue 'muted' flag set.

  1. Open Audio Midi Setup, from /Applications/UtilitiesFind_Audio_Midi_Setup.png
  2. Find 'iShowU Audio Capture'
  3. Mute and Unmute ALL channels on both tabs (Input and Output). Do this even if the channel doesn't look muted. Toggle the mute flag, on every channel, regardless. I've seen cases where it doesn't look muted, but it is.Unmute_all_channels.png
  4. Slide all volume sliders to 100%, on all channels on both tabs (Input and Output). Same here. Slide it even if it looks like it's at 100%. By doing this you guarantee to set the volume of the channel, which is what we want to do.Play_with_Volume_Sliders.png
