This is where it’s nice to have better audio and the Pi just can’t quite provide. The other main reason you might want to replace the audio output is that the Raspberry Pi’s headphone jack uses the PWM hardware for analogue audio (more on this below). If you want to use this for something else, you’re best off moving the analogue elsewhere.
Overview | Analog Inputs for Raspberry Pi Using the ...

Teaching the Raspberry Pi how to read analog inputs is easier than you think! The Pi does not include a hardware analog-to-digital converter, but an external ADC (such as the MCP3008) can be used, along with some SPI code in Python to read external analog devices. Here is a short list of some analog inputs that could be used with this setup:

How do I force analog audio via the 3.5 jack when Pi 4 is ...
https://raspberrypi.stackexchange.com/questions/118794/how-do-i-force-analog-audio-via-the-3-5-jack-when-pi-4-is-headless
I am deploying a Pi 4 on a wheelchair and require audio output to prompt the user. The Pi is headless (i.e. no monitor). On the bench, with a monitor, my code correctly sends the audio out the 3.5 jack to a powered amplifier. When I unplug the HDMI cable and reboot, the audio stops working. Any suggestions will be much appreciated.

Re: Analog 5.1 audio from Raspberri Pi. Mon Feb 24, 2014 11:18 pm. Yes, but it will cost MUCH more than the RPi. You'd need an HDMI audio extractor with SPDIF output and an SPDIF to analog 5.1 converter.

Re: Analog Audio Quality. Sat Feb 09, 2013 4:06 pm. The on-board audio isn't bad but it's not really special either I guess a lot depends on what you consider good quality. The output power is pretty low though so don't expect much from speakers (unless amplified), it also "pops" when you start / stop music playback.
