I was interested for announcements from Home Assistant using the cheapest possible way to achive this.

So from what i understand the audio usb will allow to use usbc to 3.5mm jack dacs by connecting it with an Y usbc cable.

I imagine this would be the cheapest solution for having Sendspin on a ESP32S3 supermini to 3.5mm jack stereo output without having to fidle with pins just plug in a y cable to power the esp and one end to the usbc dac and should have sound.

No idea how good this would be for music, since usbc dacs can go from cheap to quite expensive and good but i imagine the esp32s3 might hold it back in some regards.
