So now its hooked up with Jumper wires, and not plugged in directly?
If yes, did you connect the two grounds on pin 25 and 39?
If you use this,
Have a look see here and see if its related to your issue.

thank you so much for your reply !
yes now everything is hooked up with jumper wire
I just tried with pin 25 and 39 no audio at all and no screen
for this project I only use pin 27 and 22 for a 5V relay and pin 23 & 24 for an on off switch
https://pinout.xyz/pinout/pirate_audio_line_out
this page say line out use 13 pin but it doesn’t look to work and it don’t mention the 25 and 39 ground
I don’t need to use the display of Pimoroni board, what are the pin who needs to be connected to make the audio work ??
I would think about the protozero solution but for this project I really only need a audio out
Physical Pin number 22 (BCM 15), 23 (BCM 11) and 24 (BCM 8) are in use by the Pirate Audio.
22 is Amp Enable, 23 is LCD SPI SCLK, and 24 is LCD SPI CS. Connecting something else to these pins is going to mess things up.
If you look close Pin 25 and 39 have a black boarder around them, signifying they are used.
Look at the other pins labeled ground and you will see the difference.
The sound uses i2s. BCM 18 pin 12, BCM 19 pin 35 and BCM 21 pin 40, and maybe one or two more.
Thanks for the tips. I did try that I think but I’ll double check.
Fingers crossed.
when I connect :
22 (BCM 15), 23 (BCM 11) 24 (BCM 8), 25 and 39 ground
BCM 18 pin 12, BCM 19 pin 35 and BCM 21 pin 40
I also connected the pin 2 5V power
nothing is happening
I also tried with only BCM 18 pin 12, BCM 19 pin 35 and BCM 21 pin 40 but same nothing is working
the board is still working when directly pinned to the raspberry

Recently got a 10inch Picade for my birthday and figure it might be useful to document the build and setup experience with issues I encountered and how I resolved them.
Hopefully that information will be helpful - Overall I really like the Picade, my kids are getting a kick out of playing some classic arcade games now, but I don’t think I could recommend it to anyone that doesn’t have a decent amount of maker experience and a willingness to potentially macgyver a few solutions.
Both grounds pin 25 and 39 need to be connected. Other than that it looks like you have all the other required pins connected. If you also have the relay and button wired up, remove them as a test.
What are you using for jumpers? You need male to female jumpers.
Greetings. I am having similar issue. I have Enviro sitting remote right next to the Sense HAT. The Sense hat is on a Pi 3 stack with a plate between as seen in photos. I have also included a readings shot as the sensors are being read. The differences in humidity and temp are quite a bit. Any ideas on what could be causing this?
sorry I forget to mention than pin 25 and 39 were also connected
I’m using classic Dupont 2.54 mm male to female jumper

Yeah, in the config text file, any line with a # as the first character is ignored. Remove the # and that line is acted on.
#hdmi_force_hotplug=1
is ignored
hdmi_force_hotplug=1
is acted apon on boot up.
You doing everything right, I have no idea why it doesn’t work though?
I think so, thank you to have take your time to answer !
I have one last question :
using something breaking / prototyping board like ProtoZero duplicate gpio pin
Doest it means that if I use one I will be able to use GPIO which are note use by the Pimoroni board ?
Yes, the Proto Zero will give you access to all the GPIO pins. Things like i2c can have multiple devices connected. Stuff like i2s are one device only. Any unused GPIO can be setup to do what you want.
Here I used a Proto Hat to connect multiple breakouts to a Pi A+. I actually have a second one that plugs on top of the first one with a shutdown button wired up. I ran out of room on the first one.
I’m not sure if this is included in the actual picade stuff you got but I’ll post a link. It’s the assembly instructions for the 10 inch screen.
Thank you so much for that clear and concise explanation: -
This is what I did, Enabled SPI through the terminal with
sudo raspi-config
Select Interfacing Options > SPI > Enable
Next, I went to this GitHub Page and followed the instructions
Got error
luma.core requires Python ‘>=3.5, <4’ but the running Python is 2.7.16
So I followed instructions at linuxconfig.org which for me was…
ls /usr/bin/python*
then
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.7 1
Finally I ran
sudo python --version
Which gave me Python 3.7.3
Hope this helps anyone in the same situation
ok understood
thank you again for these explanation I’will use a usb sound card more easy for what I want to do and I will keep the Pimoroni for an other project
Ah thanks a lot sharpred, much appreciated for your help!
Yes, I inserted the line
disp.set_backlight(0)
just after the Initialize Display line in the luftdaten.py script. Whilst I’m running it the display is now off… and I can sleep in the dark again :-))))))
Anyway thanks a lot.
