Wanted to chime in on this if it helps. Was having I think the same problem and dewen has been helping out. Was able to update to 3.733 and have the same problem different results. Instead of the slow playback with 3.703 the new update is playing static. Changing to “BassFly with I2S Mic” allows playback on both versions but think its coming out a little thin.
