Yes, those were supposed to be 24 kHz and 4800 Hz sine waves, respectively. The glitch only happens at 100% full scale, 99.9% PCM volume fixes it (but not just lowering the mixer).

.@xiphmont promised us no stairsteps... and then C-Media came and said eh, 2x oversampling is good enough. Make sure it blatantly breaks with a full-scale input, too. What's a little harmonic distortion between friends?pic.twitter.com/2c0OX2SLoY

Wow, even worse than the first few ESS AudioDrives. They worked well in 8-bit mode, but the transition from -1 to 0 in 16-bit mode was equal to 256 normal steps.

I live in a
#retrocomputing#chiptune world where an ESS AudioDrive -- as undesirable as it might be -- is an upgrade.
