Run A2DP on ESP32-S3?

I understand that this chip has dual mode Bluetooth, that is classic and BLE. Classic is the only one you can use for audio. Has anyone got audio source transmit to a sink working on this chip? Thanks.

You are mistaken: just read the data sheet!

Thank you, an LLM lied to me and said it did.

So I'll assume that I'm using the only choice the Adafruit WROOM ESP32E feather board.

Just have to ask: Is anyone else using another chip for a solution? I find it hard to believe that all modern BT source/sink audio products use this [old & relatively expensive] chip.

I don't understand your question: on AliExpress you can find ESP32 Dev Modules starting from 2 USD and I don't think this is expensive for what you get...

My question is: Is there an inclusive list for the chips that can run A2DP? I'm really only interested in the Arduino types, not so much the Nordic family et al. I really don't care what they cost but I avoid all the Alibaba store fronts, generally.

I'm using the Adafruit 3405 product now to which I add an Adalogger which has an SD card slot. It costs $20 for the processor which is a lot compared to your $2 suggestion. I'm doing avionics development so cost isn't the first consideration.
