I have a problem with the newly bought Digi+ standard.
I have the freshly installed latest Raspbian Stretch Lite with kernel 4.9
I configured as described in manual:
after reboot, the result is:
$ aplay -l
aplay: device_list:270: no soundcards found...
interesting part of dmesg output:
[ 4.902470] gpiomem-bcm2835 3f200000.gpiomem: Initialised: Registers at 0x3f200000

[ 5.613920] wm8804: probe of 1-003b failed with error -121
The output of:
vcdbg log msg 2>&1 | grep -i hifi
001580.559: dtdebug: Opened overlay file 'overlays/hifiberry-digi.dtbo'
001580.899: brfs: File read: /mfs/sd/overlays/hifiberry-digi.dtbo
001596.000: Loaded overlay 'hifiberry-digi'
So far i haven't found any solution on this forum.
I would be grateful for any advice.
