4 channels output from ESP32

I never arrived at a satisfactory solution for the S3. My next idea would've involved an intermediary between the S3's dual I2S and the codec to translate it to one single data line.

I'm now using the P4 with TDM8 32-bit on a single data wire.

Thanks for the quick response! Too bad, I was hoping the S3 would perform better, but at least this saves me a lot of design work.

The DSP on my amplifier board already uses TDM serial input for another function, so I’m stuck with multiple I2S streams… Maybe Teensy could be an option.

P4 sounds great! I assume you're using it on an eval board or one from Waveshare/Olimex?

We bought samples of the chip from Espressif and built custom boards
