Can i use A2DP to stream analog audio and receive avrc commands, and reverse?

[marcel-hs-co]

Hello,

I am relatively new to the world of audio and its associated components. Currently, I find myself with a multitude of questions, and it appears that this project could be the ideal solution to address all my inquiries. As a newcomer, I am seeking clarification on several aspects:

With the ESP32-A2DP library, is it feasible to stream audio from an analog input to my headset? Moreover, can I program the ESP to respond to commands from the headset, such as the "next" button press, and trigger LED13 accordingly?

Is there a seamless way to switch between audio transmission and reception on-the-fly? I envision incorporating a switch to facilitate connecting to the next audio host and playing back the corresponding songs, with AVRC support seeming plausible according to the readme.

Would you recommend the use of an external DAC/ADC for optimal performance in this setup?

I'm curious if there are potential risks to the ESP if I connect the audio output from a Gameboy and wire the speaker directly to the ESP.

Thank you in advance for your guidance and assistance
