No audio in HDMI in recordings ET 10000

[gemelli47]

Hello

I found that instant recordings from any source to HMDI input, result in audio-less playback: a solution is timer recording.
Does anybody know why?

I also heard that use of a HDMI splitter is another solution: why? what kind of splitter?

Thanks for anybody's reply

Is it possible that the source you are trying to record from on the HDMI input port is using HDCP encryption, which is known to be in 2 sources either loss of video or Audio loss
