I added 2 sounds to my game which have pretty low frequencies, and they sound quite distorted through the playdate's speakers*.
Other games seem to hold up at maximum system volume, but these two sounds sound terrible at 70+%. Especially the electronic_hum sound. Is it at the resonant frequency of the speaker maybe?
Simulator and headphones plugged into playdate sound fine.

Most noticeable when playing both sounds simultaneously
See attached demo project for the sounds.
*Note: I'm using a development preview unit pdu-01. Has there been any relevant revision to the speaker?
