DAC+ADC PRO not recognized with Raspbian Stretch Kernel 4.19.127

I'm trying to get a DAC+ADC Pro up and running with a Raspberry 3 Board with a Raspbian dist with Kernel 4.19. The board is recognized and supported when booting the current Hifiberry OS on the same hardware, so the hardware setup should be fine.

When i boot the Raspbian dist with Kernel 4.19 though  the soundcard is not recognized when checking this with aplay.

I've run the Hifiberry check-system script and get the following output:

From previous postings it looks like the error messages about snd_soc_bcm2708 can be ignored?

Could you give me some help what to check out next to find out why my setup is not recognizing the DAC+ADC Pro?

My understanding is that the Hifiberry modules are part of the kernel drivers since 4.18, how can i verify this?
