When you first start using your Computer Kit, we run a quick check to see if your sound is working. If you can't hear anything, you probably saw a message about AU1.
What causes it?
Using a Monitor
If you can't hear any sound at this stage, the first thing to check is if your screen has built-in speakers. Most HDMI TVs will have these, but computer monitors don't always have a speaker.
Using DVI or VGA adapters
The Computer Kit can't send sound through these adapters, as DVI and VGA only support video and not sound.
Low TV Volume
It might sound silly, but it's worth turning your TV's volume up just in case it's low.
You will need to use an external set of speakers or headphones to hear sound from your Computer Kit. To do this, please follow the steps in our article "Using Speakers or Headphones with Your Computer Kit".
