Lost Audio i think

[oz_surfer]

I am having some unusual problems with the audio on my WINXP SP2 Machine.

The following things are confusing me:

Online videos will not play sound

In windows CONTROL PANEL - SOUND AND AUDIO DEVICES - SOUNDS (the grey button that is used to test a sound is grey and not working)

The liitle windows speaker that is normally in the corner of the toolbar near the clock is not visible (even though i have ticked it to be there).

Windows mediaplayer still plays music, and other appa that need sound still play sound.

Start > Run > Regedit

Come down to the following registry entries one at a time

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\drivers.desc

Check the following keys exist

"midimap.dll"="midimap.dll"
"mciwave.dll"="mciwave.dll"

Next and just below

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]

"midimapper"="midimap.dll"
"wavemapper"="msacm32.drv"
"wave"="wdmaud.drv"
"midi"="wdmaud.drv"
"mixer"="wdmaud.drv"

Make sure these key values exist ... once added, reboot system ... tray icon will re-appear after and the shutdown sound will be heard during the shutdown.

If any values "name" should contain a 1 at the end ... delete them ... the system won't recognize those

Thx for the reply

for the first location i have

This key is missing
"midimap.dll"="midimap.dll"

This is present
"mciwave.dll"="mciwave.dll"

I am confused about what to do next.

When i look at regedit for mciwave.dll i see

NAME
mciwave.dll

TYPE
REG_SZ

DATA
(MCI) Sound

When i double click mciwave.dll, i see

VALUE NAME
mciwave.dll

VALUE DATA
(MCI) Sound
