I’m actually experiencing a similar issue when trying to get the Pi VU Meter working with my speaker-phat + Pi Zero W when using
mopidy. After running the
speakerphat one-liner setup, all tests play fine in
~/Pimoroni/speakerphat/test/test.sh, and the VU Meter lights up wonderfully.
After the tests ran, I then installed
mopidy and with the defaults, I got sound from the speaker-phat, but no LEDs. I thought this was because mopidy wasn’t outputting via Alsa, so I installed the Mopidy-ALSAMixer package and configured my
mopidy.conf to use it accordingly:
mixer = alsamixer
output = alsasink
mixer_volume = 75
enabled = true
card = 0
control = PCM
…and here’s what I see in the logs:
2017-08-31 00:25:31,740 INFO [4055:MainThread] mopidy.commands: Starting Mopidy mixer: AlsaMixer
2017-08-31 00:25:32,784 INFO [4055:MainThread] mopidy_alsamixer.mixer: Mixing using ALSA, card 0, mixer control "PCM".

2017-08-31 00:25:33,161 INFO [4055:Audio-3] mopidy.audio.actor: Audio output set to "alsasink"
Hoping it’s something obvious that I’ve missed, but at this point, I am kind of lost, hoping and wishing for these LEDs to prance up and down the speaker-phat PCB.
Great product still, and thanks in advance for any help!
