(Simple)easy Way to Get Analog/pwm Audio From Raspberry PI Zero and Also Connecting to Crt TV

Intro: (Simple)easy Way to Get Analog/pwm Audio From Raspberry PI Zero and Also Connecting to Crt TV

  • Here i have used a simplest method to feed audio to a tv along with compsite video .........

Step 1: Choosing a Resistor

the pink resistor that i used is of 600 ohms .....you can use any resistor above 250 ohms !!!!!!!!!.....inorder to protect raspi ...

Step 2: Wire the Jumpers to the Raspberry Pi

connect tv pin directly to the composite pins(red + and white -/gnd jumpers) and video cable(compsite)

connect the audio pin(pin 13) c the image.......... to black wire

you can also use PIN 18

we are using common ground for audio and video signals....so use the tv(-) as GND for audio cable also

Step 3: Connect to Tv

Here my black cable is video(YELLOW)

White cable is Audio(RED/WHITE)

Step 4: Open Terminal in Raspi

Making pi to use analog audio

open the terminal

paste this: sudo leafpad /boot/config.txt

add this line to the end of the file: dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4

save the file or hit (ctrl+s)

DONE!!! now reboot
