(AUTO, fixed mode, etc.) different?
Select an option other than "No audio" to set the

Check the paired unit (decoder) power and operation.
Check the connection between the decoder and the
audio speaker.
If so, refer to the user's guide of the paired unit
(decoder).
If noise disappears when the cable is disconnected, the
noise seems to be mixed into the audio signal input.
Check the audio output equipment.
If the noise does not disappear even after the network
cable is disconnected from the decoder, this unit seems
to be operating normally. Check the decoder.
