I am currently wrestling with a configuration headache involving my RPi4, Kodi and an audio receiver (and a TV that doesn't support CEC standby)…
Even after installing an HDMI splitter to separate hdmi going to TV and SPDIF going to receiver, I cannot seem to find a way to only turn off the display signal (only way to get the TV to eventually go to sleep) without also turning off audio (which I want to keep playing, when using Kodi for music).
Both tvservice
and vcgencmd
simply shut down the power to the HDMI out, which obviously shuts down the audio.
Unfortunately I cannot set hdmi_blanking = 0
, as it would then start going to sleep in the middle of videos playing in Kodi…
Mirroring HDMI output so that shutting down one (the TV) doesn't affect the other (receiver) also seems impossible when running Kodi on a Pi…
Is there any command or workaround I can use, to stop sending a video signal while keeping audio on?
