While testing a fix for #10003, I discovered that the left and right channel DAC audio output on ESP32-S2 would swap randomly on play. It turns out this is known upstream problem: espressif/esp-idf#11425. The only workaround that worked for me was to entirely reset AudioOut on each play.

I'll include the workaround in a PR, but leave this issue open so it can be removed in the future if and when the upstream bug is fixed.

@MarshallMiller: probably of interest to you.
