I actually had this issue before SP1. I was hoping that SP1 would fix this
issue. I don't haev all of the symptoms that are described inteh KB article
and I've also done some of the workarounds already.

When I run dxdiag I get an error as well.. "Error: problem getting extra
sound info"

I've lost the sound on my laptop and I don't know how to get it back. I
have
an HP Compaq nx9430 with 2 Gigs of RAM. Everything was going great after
a
clean install of Vista when all of the sudden (I don't know what happened
or
updated) the sound stopped working. Now, the strange thing about the
sound
is that I can uninstall everything, get rid of the dlls and .sys files
for
the drivers. Do a clean install of the sound drivers from HP's website
and I
can press my mute button to get the icon in the systray to go to mute and
back. There are even little "sound waves" coming from the speaker in the
systray. However, when I open Mixer, I can see "Speakers" but in the
"Applications" groupbox, Windows Sounds and none of my applications come
up.
Applications is empty - yes, totally missing Has anyone ever run across
this
before? If so, what did you do to fix it? I'm at my wits end as I can't
listen to music on my laptop while I'm at a coffee shop coding anymore!!
ARGH!

Someone please help. Any KB articles I can look at or hotfixes from MS
that
I can call support and aquire?

ANY help that gets me listening to sound again is appreciated.

Thanks
Scott
