The issue is definitely not limited to warm boots only. I can confirm cold
boots with no sound and also warm boots with functioning sound. With this in
mind, the provided numbers (16 good boots across 709 boots) are largely coming
from reboots since the testing was scripted and driven by SSH.

Interesting. I haven't noticed anything breaking with reboots on this
particular system (at least so far).
