Can a general-purpose ESP32 board replace an audio board for a prototype that records and plays sound?

Sample result

1. DevKitC V4 is a general-purpose board. Its parts list shows USB-to-serial and expansion headers, but no microphone or speaker. Budget for audio parts separately. [1]
2. LyraT V4.3 has onboard microphones and an audio codec, making it a candidate for the prototype. Check whether speakers ship with the selected kit. [2]
3. A community thread describes a LyraT audio project and discusses input and speaker output. Use it to frame a test, not as a hardware specification or performance benchmark. [3]

Next: verify the microphone, speakers, cables and power supply for each SKU, then test recording and playback.
