Volume control won't stay in System Tray

[Barry Watzman]

Something has happened to my volume control in the system tray (the
speaker icon).

Every time I turn or or restart Windows, it's gone. The box in Control
Panel / Sounds & Audio Devices is checked, and I can restore the icon by
unchecking it, "Apply", recheck it, "Apply", and the volume control icon
returns and works fine -- until I next restart the computer.

Anyone know the fix for this?

That doesn't appear to be my problem.

That KB article deals with a corrupt soundvol file. That doesn't appear
to be the problem, however. First, I get no error message (a specific
symptom of that particular KB article), second, I can make the volume
control appear any time I want and it works, but I have to redo this
every time Windows restarts.

Thanks (not sure if it fixes the problem or not, yet).

Some of this suggests a connection between the volume control icon and
UPnP, and tha the fix for the volume control is turning off or removing
UPnP. Problem is, I need UPnP for voice chat in MSN Messenger 6.2.

Go to Control Panel and open Sounds and Audio Devices, then click the Audio
tab.
Confirm that you have the right devices selected.

If you had followed the whole thread, you would have seen that I had
tried that before posting (I'm NOT a newbie, quite the opposite).

Kelly's manual registry edit fixes resolved the problem (in fact, only
the 1st two fo the four fixes suggested).

There is a VERY OBSCURE interaction between UPnP (Universal plug and
Play) and the mixer icon in the system tray, apparently a bug, which is
the cause of the problem. It occured after I enabled UPnP, which I did
because I wanted to use live audio 2-way chat in MSN Messengr 6.2 (UPnP
is required for that). The bug is "real", I wasn't doing anything
wrong, everything that was supposed to be setup was setup correctly. I
don't see why there should be any interaction between UPnP being on and
the audio mixer, but apparently there is.
