sound preferences

[csaenemy]

Hi,
I have been using Sabayon 4.2 with the Gnome desktop since it was released. I have had all the usual newbie problems with kernel upgrades etc. but am steadily learning. I have little or no previous Linux experience and no programming or scripting knowledge.
This is not a major issue, but one of those niggles that I cannot find an answer to, no matter how hard I search.
How can I attach sounds to events, for example a startup or shutdown sound? The logical GUI based route ought to be through System/Preferences/Sound, but all I am seeing on the Sound Effects tab is a greyed out Alert Volume slider bar.
If it's necessary for me to use terminal commands I would appreciate clear instructions as to exactly what to type.
Thanks for any help anyone can offer.

Further to my original post, when I type "gnome-volume-control" into terminal this is the output:

~ $ gnome-volume-control
** (gnome-volume-control:28504): DEBUG: Disabling debugging

** (gnome-volume-control:28504): WARNING **: Unable to find stream for bar

Obviously something is missing or in the wrong place.

KDE has much better support for this than gnome, not sure suppoer is even there tbh

It will probably be solved when Sabayon Linux 5.0 is out.

Thanks Wolfden. I already found this page through a reply to another post on here, but unfortunately still can't find the solution. I did as instructed under the heading "System sounds do not play (GNOME)", but to no avail:(
