Raspberry TV tuner not working

I´m solving problem with not working raspberry TV tuner
Actual configuration is:
RPi3 + hifiberry Digi+ and Raspberry TV tuner
If there is connected only RPi3 and raspberry TV tuner without hifiberry Digi + it is working, but all together I can´t see in TVheadend any tuners.
I think problem is how to switch raspberry TV tuner to second raspberry SPI port (Hifiberry also working over SPI)
My logs:
Anybody have same configuration?
Thanks for your help


The tuner definitely works with OSMC (tested here); but I’ve not tested it with a HiFi DAC as well however.

I don’t know if this is possible.
