SP For those of you who have issues with Digi 2 Pro:
1. The HAT should be plug and play on Pi4 with HifiBerry OS not sure other Rpi models. I did not have to edit config.txt file at all with any overlays.
2. Your working -aplay should look like this:
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_digi], device 0: HiFiBerry Digi+ Pro HiFi wm8804-spdif-0 [HiFiBerry Digi+ Pro HiFi wm8804-spdif-0]
Subdevices: 0/1
Subdevice #0: subdevice #0Your correct config should look like this:
# Please note that this is only a sample, we recommend you to change it to fit
# your needs.
# You should override this file using a post-build script.
# See http://buildroot.org/manual.html#rootfs-custom

dtoverlay=hifiberry-blockedIf it’s still does not work it’s probably a HAT hardware/ firmware issue. I can confirm this because my first had issues with overlay and sound output. The second just worked perfectly…..
Hifiberry needs a better quality control/testing prior to shipment…. Just saying. I am very pleased with a sound after replacement.

HiFiBerry team All our boards are tested after production and work when they leave the factory. However, there seem to be incompatibilities with SOME Pi's (maybe due to some hardware changes in the Pi). We're waiting for some boards to arrive here to find the root cause of this issue. I expect that we should get these in the next week. When we have the boards here.
Please no more speculations, we'll come back when the root cause has been identified.
