Hi,
I have the exact same problem. When I select the „HiFi Berry DAC+ (PI 2/3)“ I see no soundcard in the Alsamixer. When I select the „HiFi Berry DAC (PI A/B)“ I see the soundcard in the Alsamixer and have sound.
With the „HiFi Berry DAC+ (PI 2/3)“ selected I get following error with dmesg | grep hifiberry

I have a fresh install of m2p_stretch_rpi_245.img.zip. Already tried also with a fresh install of m2p_rpi_default_244_wps_ap_expand.img.zip. I have also tried differend Rasperry Pi 3B v1.2
What can I do?
P.S. Sorry I’m a Linux newbee, so if some informations are missing tell me how and I will give you the informations needed 🙂
Thanks!
