No microphone as user Pi on version 20210402

[tardich]

Hi,

I'm using VoiceKit 2.0 on a RaspberryPi 3B, and I can't get the microphone to work from the Pi user ( ~/AIY-projects-python/checkpoints/check_audio.py plays test sound but fails to play back the recording. The same command run as root plays test sound and also the play back.

Doing my tests from a SSH connection.

Did them with just the image as downloaded, and also after a full "apt dist-upgrade". I would think this is a permission issue somewhere, but I can't just pinpoint what's missing.
