The analogue audio output on the Raspberry Pi gets a bad rap, although I reckon it’s just fine for many things. Raspberry Pi If you want to produce an error or warning tone, or if you’re building a toy that says something or makes a sound effect, or even a communication device, it’s generally good enough.
How do I add analog audio out to the Raspberry Pi Zero ...

PWM-based audio like the other Raspberry Pi models: Adafruit has a nice article that covers the electrical schematics based on the early RC filter of the original Raspberry Pi and the buffered, higher quality audio output of the B+ and Raspberry Pi 2. It also describes how to adjust the used pins in the device tree overlay to change to accesable pins on the Raspberry Pi …

Then you can set the analogue jack as output device (in LE 9.2.6 also together with HDMI audio) in Settings / System / Audio /Audio output device . If everything is set properly and audio output through analogue jack still does not work, you may perhaps try another options: Onboard analogue audio options in config.txt (3.5mm jack) - Raspberry Pi Documentation

GPIO #18 is also known as PWM0 and in the original Pi was coupled with a very basic RC filter to create the audio output: If you don't mind getting a few 150 and 270 ohm resistors, and two each of about 33nF (also known as 0.033uF) and 10uF capacitors, you can basically recreate those two filters. Now all you need is access to PWM0_OUT and PWM1_OUT, …
Pi 4, analog out and DAC - DACs - Volumio
https://community.volumio.org/t/pi-4-analog-out-and-dac/12412
The 3.5mm audio out is garbage, either go for a HAT like the Allo Boss or Hifiberry DAC+ Pro (plus Pi 4 case) or consider the iFi Zen DAC which is a very fine headphone amp/DAC for £129 (32bit/384kHz and MQA). i would like to use a raspberry pi 4 as a music server with volumio and I’m trying to figure out how to do it all.
How is 3.5 mm analog audio out on PI4? - Raspberry Pi Forums
https://forums.raspberrypi.com/viewtopic.php?t=243555
using the 3.5mm audio out, the sound was noisy and distorted, with horrible quality. if the pi 4 does not have a dedicated audio IC, i believe the analog audio quality is the same as previous generations. With the old driver, the Pi's sound had problems, but horrible distortion wasn't one of them.

3.5: Analog video output. The Raspberry models B have a 3.5mm jack that looks like a regular headphone jack but is actually a 4-pins audio and video jack. When configured correctly, you can use this to connect to an older tv without needing HDMI converter boxes. This analog video signal is also known as composite or s-video.

Raspberry Pi 4-pole Audio/Video Jack. 49. By Matt on July 22, 2014 Model B+. The Pi Model B+, Pi 2, Pi 3 and Pi 4 features a 4-pole 3.5mm audio jack which also includes the composite video signal. This has allowed for the removal of the composite video socket found on the original Model B. The new jack is a 4-pole socket which carries both audio and video signals.
