Installed Chiisaa skill from marketplace and installed it. The LED was workinf fine after that, but not the audio input & output. Finally went to /boot/config.txt and commented out the below lines.
#dtoverlay=i2s-mmap
#dtoverlay=googlevoicehat-soundcard
#dtoverlay=googlevoicebonnet-soundcard
works like a charm now.
If you face any issues setting up Raspberry Pi4B + AIY Voice Kit V2, feel free to post in this thread so I can help.
I was wondering how the AIY Voice Kit V2 is working out for you? Does it pick up you talking and commanding mycroft well? Is it better or worse than other mics you’ve tried?
