My audio applications have stopped working

Audio device may be in use by another application

Mac OS X: No audio from certain multimedia content

This may mean that one application has changed your computer's audio settings to a sample rate that is too high for other applications to use. The problem may appear when you try to play audio content from BBC or NBC in Real Player.

Apple suggests:

To use the Mac OS X audio drivers:

  1. Open Audio MIDI Setup and click the Audio Devices tab.
  2. Choose Default Output: Built-in Output and System Output: Built-in Output from the pop-up menus.

Then set audio output to 44.1kHz 2-channel 24-bit

  1. Under Properties for: select Built-in Output.
  2. Set the Audio Output Format to 44100.0 Hz. 2ch-24bit
  3. Quit Audio MIDI Setup.

What if it says output is not supported?

Under Properties for: choose Built-in Output

Thanks, that was exactly my problem. Now if only I could figure out what application changed this setting in the first place :-/

You are wonderful! You just saved me from re-installing the system software because I didn't know why my audio wasn't working with internet browsers.

That was a Godsend, Thank you. I've been tearing my hair out over this for over a month - tried all the logical things but nothing doing.

What a silly place to house such an (apparently) important setting!!

Something changed my settings online. couldn't figure it out. google searched "audio in safari stopped working". this was top in search. read contents. went to audio midi setup. saw that Hz was selected to 96k. changed back to 44.1. everything works now. you rock!

Thanks. For me the problem was Real Player 11 changing the settings.
