dTV board SPIDF output independent of HDMI in Linux


Hi all,
I am running Libreelec and have discovered that I cannot get SPIDF output without an attached TV.
It seems that the SPIDF output on the dTV board is somehow slaved to the HDMI digital output. Is there a way to decouple them such that I can have SPIDF output from the board when the TV is switched off.



Having done some testing, it seems that this is a AML audio driver issue which means it is common behaviour to both Linux and Android. A nasty cludge on their part which would require a rewrite of the driver which no Linux developer seems able to perform. In short this seems an unsolvable limitation of the S912 unless Amlogic apply themselves (ie its not going to happen).
