Re: Gnome Audio Alerts

Fortunately, the audio card was recognized.  I am able to use the audio
card to play music and videos, etc.  It is only the audio alerts from
gnome that do not work.  Since then, I had another problem with my
system which resulted in dumping many of my personal settings (read
config files).  When gnome came back up, the alerts were working again.
Somewhere in one of the configuration files in my personal directory
there was an odd setting that caused the problem.  Unfortunately, I have
no idea which file or what setting.  But in any event, the alerts are
again working the way they are supposed to.

I suspect that many of the intermittent and odd problems I have from
time to time on this system is the result of using an old laptop
(Gateway M675).  Several features of the linux system are non-functional
on this laptop, especially the ability to suspend to ram, or hibernate
to disk.  I've done some research, and this is a common problem with all
linux distros with this laptop.  As far as I can tell, no one has solved
that particular problem.

Thank you for responding to my post, Martin.  I appreciate your help.
