HDMI to FM converter

I'm building an HDMI to FM converter to listen to audio from my amplifier using radio. To achieve this, I've gathered available modules and created a custom converter. The headphone amplifier and potentiometer are used due to the significant disparity in sound volume between the laptop and amplifier. This setup allows me to adjust the volume levels effectively. The FM module has a microphone enabled by default when no mini-jack is plugged in, but it can be disabled via solder pads on the board (as shown in one of the pictures). To connect the modules, I'm using an old headphones cable for interconnection. Here are the components used: HDMI to RCA Converter: https://www.aliexpress.com/item/32815095086.html?spm=a2g0s.9042311.0.0.27425c0fFEunVL Headphone Amplifier: https://www.aliexpress.com/item/32873798605.html?spm=a2g0o.detail.1000016.1.332a115c4clxZE&isOrigTitle=true or https://www.aliexpress.com/item/32775144587.html?spm=a2g0s.9042311.0.0.27425c0fFEunVL Potentiometer 2x10k logB: http://www.dareltek.pl/pliki/pot.stereo.pdf
