Public bug reported:
I noticed some dynamic distortion starting today. It is not periodic but
rather seems to be effected by the music played. Running a VM i do not
get the same problem with windows. The distortion is also heard through
the Analog port of my Lenovo USB C Dock Gen 2. I checked with different
headphones/speakers the problem persists.
