How to Prevent Streaming Silence
If you find you’re streaming silence, it’s likely you selected the wrong sound capture device in Settings>General options. It’s also possible that you haven’t enabled the correct volume control in your sound device configurations. All of this is covered in “How to Configure Your Sound Capture Device.”
A sound device may have a line-in, microphone and other inputs, but on certain devices, only one can be active at a time. You have to make sure the right ones are activated, not muted, and that the volume level is loud enough.
Disable your “Sound Processing” settings in the Equalizer, AGC, DSP and SoundCard AGC tabs to make sure none of them are causing the silent stream.
You can tell that you’re capturing silence on the input when the VU meter on the main SAM Cast window doesn’t move. However, if it is moving and the VU meters on the encoders aren’t, something on the sound processing panel was probably incorrectly configured.
