The Raspberry Pi Zero uses a mini HDMI port, so you will need a mini-HDMI-to-full-size-HDMI lead or adapter. On the Raspberry Pi 4 there are two micro HDMI ports, so you will need either one or two micro-HDMI-to-full-size-HDMI leads or adapters, depending on how many displays you …
HDMI Audio Extractor - Raspberry Pi Forums
https://forums.raspberrypi.com/viewtopic.php?t=292376
Re: HDMI Audio Extractor. Thu Nov 26, 2020 6:17 am. The audio extractors work great only problem is sleep as they can cut a second or 2 off output. I thought I could use one for a voice AI and have the same clock on the I2S as 2x I2S mics. The sleep problem killed that idea with notification bleeps. A usb cheap sound card, dac or I2S is pretty ...
How to get better Audio quality from audio jack output ...

The audio out of the Pi is pretty poor in general. I think it is best to use either a USB sound card, or a GPIO header sound card like one of these. The reason is that the audio codecs which they use are far more linear then a pulse width modulation (PWM) strategy which the Pi uses. This linearity implies much better sound quality.
pi 3 - Raspi3 audio sounds like rubbish - Raspberry Pi ...
https://raspberrypi.stackexchange.com/questions/57383/raspi3-audio-sounds-like-rubbish
IMHO the audio quality never was great on the original Raspberry Pi model A and B. It even got worse with the introduction of the A+, B+ and all following models. There are only two things you can do to improve the sound quality: set the volume gain in alsamixer to at least 0.0 dB; you may try to disable audio dithering in config.txt
Getting Hi-Fi sound from Raspberry Pi - Electronics Weekly

In both cases, audio was extracted from the HDMI digital stream – While Raspberry Pi analogue audio output is not so wonderful, its handling of digital audio over HDMI is. There are expensive HDMI audio breakout boxes, but some computer monitors include HDMI DACs – Electronics Weekly used a ViewSonic VX2260wm.
Build an Airplay Receiver Using Raspberry Pi – Jeff Thompson
https://www.jeffreythompson.org/blog/2020/04/29/build-an-airplay-receiver-using-raspberry-pi/
Bluetooth is an option, but the sound quality is ok at best. Apple’s Airplay goes over wifi and gives much higher-quality audio, but you’ll need some way to get that signal to your receiver or amplifier. There are lots of options on the market, but if you have a Raspberry Pi lying around, it makes a great and very cheap solution!
RPi 2 poor audio quality : raspberry_pi
https://www.reddit.com/r/raspberry_pi/comments/2yu3kd/rpi_2_poor_audio_quality/
The Pi's 1/8 inch audio out jack is powered by an 11 bit DAC. The audio degradation when using software to reduce the volume is a direct result of this. Besides this, it has a background hiss, and it crackles. HDMI is a different story. HDMI uses the DAC in the TV or amplifier. The hiss that you are getting is coming from your TV, not the Pi.
