audio - Play 2 sounds simultaneous HDMI + analog ...
https://raspberrypi.stackexchange.com/questions/7955/play-2-sounds-simultaneous-hdmi-analog
The Raspberry Pi can only use one output. This is by hardware design and is to do with DMA (Direct Memory Access) You can plug in a USB audio device then you can use two output sounds at the same time. The next best thing could be to play a sound out on HDMI, switch to Analog and play a sound there.

In this two cases, the program runs but the sound output is HDMI. If I launch the program with Raspberry OS running with analog audio selected with pulseaudio, I have no problem. Just, I don't know how to configure the analog audio output by default at startup. Thanks in advance for your help .

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.

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 wish to attach. You should connect any HDMI leads before turning on the Raspberry Pi.

If you want sound over HDMI, config.txt should have both: hdmi_group=1. hdmi_drive=2. You need them both set because hdmi_group=1 tells the kernel we are using CEA mode (for TV's, has sound) instead of DMT mode(for monitors, no sound) and hdmi_drive=2 tells the kernel to use HDMI if available. (HDMI mode has sound, DVI does not.)

For these measurements we used a standard Raspberry Pi OS image (current as of 26 Feb 2016, or June 2019 for the Raspberry Pi 4), at room temperature, with the Raspberry Pi connected to a HDMI monitor, USB keyboard, and USB mouse. The Raspberry Pi 3 Model B was connected to a wireless LAN access point, the Raspberry Pi 4 was connected to Ethernet.

HDMI and Analog audio at the same time through firmware ...

sudo amixer cset numid=3 2 speaker-test # will output through hdmi /opt/vc/src/hello_pi/hello_audio # will output through analogue This uses alsa for hdmi and openmax for analogue. The problem with alsa is the amixer switch only allows one destination at a time, but the audio service would support both if it were requested.
