No Audio from Crickit Hat, Even After Pad Cut

Post by gallaugher »

I'm working with a Pi Zero WH and I've attached it to a Crickit. I'm trying to drive audio through a speaker I've wired up into the speaker connectors on the Crickit, but I get nothing.

Ran setup scripts, rebooted, ran again. Didn't hear anything, but didn't notice any errors, either.

I did cut the cut the copper between the pads as indicated here:
https://learn.adafruit.com/adafruit-cri ... ker-output
And I used a multimeter - no sound when probes are on the different pads. When probes are on same pad I get sound.

Setup trying to play through the Crickit is on the right, below. No audio
Comparable setup, but taking same speaker / alligator clips & running them through an RCA wire going into the RCA port of an HDMI to VGA out on the Pi mini on on the left. This generates low volume audio (as mentioned before, and not unexpected, given there is no amp on the Pi Zero).

This is what I get when running command below with setup on right (Crickit)

Error: Unable to open font
Audio codec mp3 channels 2 samplerate 48000 bitspersample 16
Subtitle count: 0, state: off, index: 1, delay: 0
have a nice day ;)

And this is what I see when I run the setup on the left (HDMI jack)

Only difference in output I notice is the "Unable to open font" error comes first from the Crickit, and at the end when running via HDMI

Strangely, when I tried accessing alsamixer the first couple of times I ran the test on either setup, I couldn't adjust the volume at all. It was fixed at 100 for both playback and capture, but after a reboot or two, I was able to adjust the volume on the Crickit and HDMI setup, still no results from the Crickit, though.

Any thoughts?
Thanks!

Try adding the "-o alsa" flag to the omxplayer command. For example

Code: Select all

omxplayer -o alsa thanks.mp3
