DAC2 HD + RPI4 / hifiberryos not working


I have problems to get a DAC2 HD running with a RPI4 and hifiberryos.  With volumio it works, but not with hifiberryos. I tried different sources, and different releases (20200908). I have access via webgui and ssh, but there is no sound at all coming out, even with speakertest. 

# /opt/hifiberry/bin/update --experimental
you are already using the latest version (20210203 vs. 20210203)

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0]
Subdevices: 0/1
Subdevice #0: subdevice #0

One strange thing I remarked, it shows up as Beocreate? Feedback -> "Together we can make Beocreate 2 better…" and unter "Diagnostic" it says "DAC+ Zero/Light/Miniamp". But again, in volumio it works, dac2 hd is detected and playing.

Seems to be the same problem as here:

Fixed by adding "dtoverlay=hifiberry-dacplushd" in /boot/config.txt 

best, Felix
