If you're streaming one of our videos and you can't hear the audio, it may be due to the video volume being turned down, your device's volume being turned down, not having your external speakers or headphones plugged in by mistake, or a firewall block. See below for instructions on how to check for each scenario.
1. Check The Video Volume
On the course video, hover your mouse over the video window and click the speaker icon. Make sure this volume bar is turned up enough and is not muted.
If that looks good, check the volume on your computer or mobile device.
2. Check Your Device's Volume
If you're watching the course on a computer, make sure your computer's volume is turned up.
On a PC, right click the speaker icon in the bottom right corner of your screen. Adjust the "Master Volume" bar to make sure the computer sound is turned up.
On a Mac, click the speaker icon in the top right of your screen and make sure the volume is up.
Some laptops will also have volume adjusting keys on the keyboard as well.
On a phone or tablet, press the volume keys on the side of the device to turn the sound up. Make sure this is turning up the media volume rather than the volume for your ringtone.
3. Check Your External Speakers or Headphones
If the video and device volume are both turned up, check to make sure your speakers are plugged in, and no other audio devices are interfering. For instance, there might be a set of bluetooth headphones that you didn't realize were paired to your computer! If anything else is paired or plugged into your computer, the sound might be coming through there, instead of your intended speakers.
4. Check for a Firewall Block:
If you are still unable to hear the video at all, it may be blocked due to your network's firewall. If that's the case, your network will need to to unblock cdn.jwplayer.com in order to successfully play the course videos.
