Launching with the Kernel 4.15.0.47.50 v4.15.0-47.50 resolves the issue. The more recent kernel (above this one) has the issue. Seems the more recent kernel introduces some bug that needs to be fixed.

However, when I close it down (to sleep) and then return, all the sound disappears. The only way to get back the sound is to restart the laptop.
