hifiberry-digi on pi4 not working.....

[Skywatch]

I even reinstalled pulseaudio to see if that was an issue, but problem persists

DMESG gives the following clues......

wm8804 is being reported so I checked with lsmod | grep wm8804

Terminal

Not sure how this is happening as etc/modules has the following....

Terminal

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

uinput
#snd-bcm2835

#snd_soc_pcm5102a <---This one must be commented out.
snd_soc_hifiberry_digi

and etc/modules.xbian has the following...

Terminal

xbian@Cinema4Film ~ $ aplay -l
aplay: device_list:272: no soundcards found...
