I spent 2 days trying to get this to work. When I saw your diagram at 2m29s I finally realized what I did wrong; I was probing pin 12+13 instead of GPIO 12+13 Geez such a simple error. Thanks fellow Dutchie
It appears to me that in latest releases the only audio outputs that work for Zero 2 W is GPIO18....I had to use these commands in config.txt dtparam=audio=on dtoverlay=audremap,enable_jack dtoverlay=pwm-2chan,pin=18,func=2
Files in /usr/share are under the control of the package manager, so it is better not to edit them. I think you can set the defaults.ctl.card and defaults.pcm.card values in the /etc/asound.conf file or in the /etc/alsa/conf.d/*.conf files.
any amplifier using analog signals should work, so this one also will be alright. Be sure to have it connected between the audio filter circuit and the speaker.
Good question, i think you will get audio if the gpio are connected correctly but i can't asure you the best audio quality though I have never tried it
I found this solution personally inferior because it takes up a lot of space and you lose a usb port, my solution is primarily meant for people who want to make compact handheld devices

Best video ever. Probably better than the F1 today
On Pi Imager CTRL+SHIFT+X before writing, allows you to enable ssh and enter wifi information (as well as other options).
Bonkers im learning so much here
the 3.5mm jack will fit perfectly fine in the usb port if u press hard enough :)
My thoughts exactly.
Your code worked! Be pulling my hair out chat gpt recently 😂

Thank you very much for the contribution. A question then on zero 2w will connect the Jack to gpio 18 and gnd?
Deze video is underrated man. Over een jaar sta je op een miljoen vieuws.
enige video die werkt op die internet

Thanks for video, how did you calculate the values of the resistors and capacistors
awesome video, very helpful! thank you :D
Instead you can go for Bluetooth option for streaming audio. But i would not recommend for rpi zero 2 w as it has low processing power.
I would like to connect microphone and headphone audio to the zero, can you please
make a tutorial how to do that?
great to learn. Dank je wel!
How can I get the easy access files that you have of the ssh and wifi?
Muchísimas gracias amigo, el único tutorial q me sirvió, tu sabiduría me servirá para un proyecto :)
Great what are you making?
Im still planning on doing a tutorial on how you can directly connect a small 4-8 ohm speaker to the system
Can I probe the pins 18 and 12?
Does it Still work if i only use one of the PWM Channels? I Only need Mono Audio.
Nice work 👍
How to connect mic with it ?
Can I directly add my Pam8403 (amplifier board) with the GPIO without making an extra circuit with all the capacitor and resistance stuffs? Reply plz
any amplifier using analog signals should work, so this one also will be alright.
Be sure to have it connected between the audio filter circuit and the speaker.
High-pass filter is necessary as the signal is pwm modulated. Here the filter is filtering out the audio signal from high frequency PWM signal.
@@biswajeetsingh4994 what if I use a soundcard instead?
Is it a simple task to combine the left and right to create a mono playback through only one filter circuit?

Got any projects in mind for this?
my pico 8 handheld, basically the whole reason i even started doing all of this hardware stuff
can i use it without the audio filter
you can but it will sound absolutely horrid
thanks!
Can we get 5.1 output?? ..
Is that an analog signal?
Yes, can we???...
Thumbs up
I ike his voice, he sounds hot
