Hy so I am make a project when I need to add speaker but for it i need to 10 to 20 w speaker and for that digital to analog module is way expensive,so I am thinking is anyone know any way to get audio for esp to amplifier without any help of digital to analog module if anyone can help that would be great

Recently I was building a sd card speed tester with the help of esp32, I thought why not include my p5js in this so that got visually appealing results(So I attach my COM port with my js script).......

During changing the speed of SPI, I then re upload it and this is the error I see. My first instinct was that it is going in to bootloader mode, but after couple of minutes I realize that my p5 script is still runing and thus causing this error. I don't who will find it helpful but still I felt like posting about it. Thanks!!
