After the last Rasperian OS upgrade HiFiBerry DAC+ Pro stopped working.

aplay -l

Karte 2: sndrpihifiberry [snd_rpi_hifiberry_dacplus], Gerät 0: HiFiBerry DAC+ Pro HiFi pcm512x-hifi-0 [HiFiBerry DAC+ Pro HiFi pcm512x-hifi-0]
Sub-Geräte: 1/1
Sub-Gerät #0: subdevice #0

uname -l

Linux 5.4.83-v7l+ #1379 SMP Mon Dec 14 13:11:54 GMT 2020 armv7l GNU/Linux

Where to search the problem?

Thanks

Could be some issue with Pulseaudio. Also the fact that it shows up as "card 2" shows that something seems to be wrong here. If you disabled on-board sound it should be card 0.

A somewhat clumsy solution: Disabled internal sound devices (analog, HDMI).

Added line

blacklist snd_bcm2835

to file

alsa-blacklist.conf
