Hi, Various users have experienced this (even me). I do get a sound however if I use a different DE - the best one for startup and shut-down sounds is Cinnamon DE but it no longer works properly for me now in respect of wallpapers not showing. I do get sound with LXQt at startup and KDE (Plasma) at startup, but not on Core (Gnome). I should also point out that I am using a Creative SoundBlaster Audigy 5.1 Sond Card which meant I had to blacklist both HDMI and onboard sound to get any sound out at all!
