Same issue with an ASUS ZenBook 3 UX390UA. I experience the issue as a volume dependent cross-talk between the channels, predominantly affecting the left channel when a medium volume sound is being played in the right channel, but to a lesser extent (lower volume of the cross-talk) affecting the right channel as well. Going by hearing the cross-talk seems to be 1-bit audio.
The common denominator seems to be the (newly supported) Realtek ALC295 driver:
