Pirate Radio VU meter doesn't work


I’ve recently bought Pirate Radio and managed to turn it into internet radio (starting from raspbian stretch lite). Although audio works well, the VU meter unfortunately doesn’t :( I’ve checked the forum for the answer and found info about /etc/asound.conf file, however it looks like it wasn’t created during installation process. Can I just create that file and if yes, than what should it include? Or does the problem lays much deaper?

For additional info, the LEDs turn on for a brief moment during booting and I can control them using python scripts.

Thanks in advance!

For future lookers for answer to this question - I’ve managed to solve this problem by installing also a “basic” pHAT BEAT software - now both audio and VU meter works like a charm!
