I'm struggling to get my HiFiBerry DAC2 Pro working with a condenser microphone on my Raspberry Pi 5. Despite installing ALSA (alsa-utils), enabling the correct overlay (dtoverlay=hifiberry-adcpro) in /boot/config.txt, and verifying hardware connections, arecord -l shows no capture devices. The kernel (uname -r) is up-to-date, and dmesg shows no obvious errors, but the ADC isn’t detected. The mic works elsewhere, so it’s not faulty. Could the issue lie with the microphone set up with phantom power? For reference im using a behringer ECM8000 measurement microphone.
If you've worked with this microphone before could you also leave some set up reccomendations? Thanks!!

HiFiBerry team There are two different things:
First: You did NOT load the correct driver. There is nohifiberry-adcpro overlay.https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/
dtoverlay=hifiberry-dacplusadcpro
Without the correct driver, you can't run arecord at all.
Also , the DAC2 ADC Pro does NOT provide phantom power for your microphone. You would need something that can provide 48V phantom power:https://www.hifiberry.com/shop/0-development-kits/stage-devkit/
