Correction: Even with Fast Boot disabled, when using Restart from Windows 10, this behaviour is reproduced. When booting after a Power Off, it works.
** Description changed: On ZenBook UX433FN with Dual Boot After rebooting from Windows 10 (where the sound works OK), the sound in Ubuntu *19.10 is distorted and just available for 2-3 seconds, then silence 2-3 seconds, etc. The issue went away after I've disabled Fast Boot in BIOS. + Correction: + Even with Fast Boot disabled, when using Restart from Windows 10, this behaviour is reproduced. + When booting after a Power Off, it works. It seems to be an older bug that returned (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1784485).
