If your internet broadcast audio source isn't showing any levels in the visual audio level meter, there are several potential causes to check.

First, verify that you have the correct audio source selected for your internet broadcast. In the Internet Broadcast window, look at the Broadcast Source section and check the visual audio level meter. If no levels are displayed, click the Change Source button to select the correct audio input device.

The most common audio sources to select are:

• PlayIt Live Main Mix - this captures the audio output directly from PlayIt Live
• Input from your mixer - if you're using an external mixing desk, select the appropriate input device
• Stereo Mix - this captures all sounds played by your computer, though this option isn't available on all systems

Make sure you're selecting the audio source that corresponds to where your programme audio is being routed. If you're using PlayIt Live without external equipment, PlayIt Live Main Mix is typically the correct choice. If you're using a mixing desk, select the input device that corresponds to your mixer's output to the computer.

Check your computer's audio settings to ensure the selected audio device is functioning properly and that the volume levels aren't muted or set too low. You can test this by playing audio in PlayIt Live and confirming you can hear it through your speakers or headphones. If you can hear audio but the broadcast source meter shows no levels, there may be an issue with the audio device routing or the device may not support monitoring of the output signal.
