Hello from the pygame community. Contribute - pygame wiki
This example lets you play the drums with Drum HAT!
Pads are mapped like so:
7 = Rim hit, 1 = Whistle, 2 = Clash
6 = Hat, 8 = Clap, 3 = Cowbell
5 = Snare, 4 = Base
Press CTRL+C to exit!
XXX When I press any of the pads I get: XXX

Did you run
curl https://get.pimoroni.com/drumhat | bash
What happens if you run the test.py file?
I don’t have a test.py to try.
Where should it be?
OK, I re-installed it and now I get:

My link above will take to to that file on github, all the examples are here.

The learn section is down at the moment, its been unaccusable all day.
What are you using for sound?
OK, I downloaded and ran test.py and that works fine but there is no sound (RPi Zero W).
Ok, you must be using HDMI for sound?
Can you get sound on that Pi from another source like say a youtube video, or music?
Do you have the two drum folders, that’s where the sound file are?
@Caperjack1953 Hey Jack, I do believe you just recently setup a drum hat.
Was it Buster, and what sound device did you use? DAC, Analog, or HDMI?
I’m using USB sound:
4.048182] usb 1-1: Product: iMic USB audio system
Does it it actually produce sound?
This produces a loud tone!
speaker-test -c 1 -t sine -f 500
When I run drums.py it fails again with:

not sure ,haveing a really bad memory/confusion day today ,Ok checked it a bit ,I’m still using the orignal setup of PiZero ,The Speaker Phat and Piano and Drum Hat , I just copied /pasted that new bit of code you gave me when I got the other DrumHat from you and tested your hat …if that any makes sense
Ok, I have have almost the same setup, Pi Zero, Pirate Speaker, drum hat, piano hat. Pretty sure its Buster, just can’t remember if I set it up before or after the switch to Pulse Audio in Pi OS. I followed the itty bitty beat box tutorial. Learn section is down and out at the moment now though so i can’t link to it?
I thought you might have been tinkering with the other Drum Hat you have, the one you got in the trade of stuff with me.
