Mac-mini audio out

I have a Mac mini (2011) which doesn't produce any sound through the audio out. I've tried with speakers, headphones, etc,... but no sounds to hear.

What can be the problem?

Solution 1:

Open the Sound Preferences Pane in System Preferences and make sure that the settings for output device, Output volume and Mute are set appropriately:

You might want to plug in a set of headphones or external speakers while this panel is open to confirm that the hardware is registering correctly.

If those settings all seem to be correct, Apple has a knowledgebase article: Troubleshooting issues with no audio from built-in speakers on Macs

I have also seen instances when the settings in the Audio Midi Setup panel (You'll find it in the Utilities folder) are incorrect. Confirm that the settings for the Built-in Output are 44100 Hz 2 channel-24 bit.

If all of this fails, I have seen reports of this problem having being solved by reinstalling the system software. You might want to try that before taking your computer in for repair.

Solution 2:

Possible issues:

• Volume set too low
• Default audio output not set correctly
• Hardware issue, go to Apple Store if possible
