What is this about?

Incoming audio channels are expected to have some data on them. If they don’t, this is indicated by a zero audio level.

What does this look like in the analysis?

If you open Advanced WebRTC Analytics, then for the incoming audio channel, you will see that the totalAudioEnergy is flat at 0 for the session duration.

Potential risks

This indicates that there’s no incoming audio. Probably since the wrong audio device is being used on the other end, the audio is muted throughout the session or a media server along the route is malfunctioning.

Suggested actions to take

  • Validate on the sender side if audio is being sent
