CORIOmaster & CORIOgrapher Help
I can't hear any audio
What's the problem?
I am trying to play audio but I can't hear it, or the sound is poor.
Why does this happen?
General problems with audio:
- Audio is disabled for the input or output.
- The audio source is muted.
- The audio output is muted.
- The canvas or output is cut to black. Cut to black also mutes audio.
- The input audio level is turned down low, or the output volume is turned down low.
- The audio source was changed by a preset.
- The source device or output device might be muted.
- There might be a loose connection, mislabeled cables, or problem with your audio device.
-
The audio source is not compatible with your CORIOmaster.
- Your CORIOmaster only plays embedded audio in uncompressed PCM format.
- Your CORIOmaster only plays audio with a frequency of 48 kHz.
If you're trying to play audio with the S/PDIF and analog audio module:
-
You might have your audio device connected to the wrong output.
Each output is associated with a single canvas. Output 1 is associated with canvas 1, and so on.
If you're trying to play audio with the Streaming media and 4K playback input module:
- You might be trying to listen to a stream with low latency. CORIOmaster automatically mutes streams with low latency.
- The audio from a media item might not be compatible with your Streaming media and 4K playback input module.
If you're trying to play audio using the S/PDIF output of a CORIOmaster micro:
- You might be listening to the wrong window.
