Microphone did work now it doesn't

[Guest]

The microphone is working.

The sound card is working.

The problem has occured before and a microsoft certified
dealer reinstalled the recording devices.

I would like to fix this problem myself.

These are the additional messages/issues experienced:

Through the control panel, the Sounds and Audio Devices
Properties application is launched. Choosing the Voice
tab, the Test hardware... button is selected.

After going through a timed diagnostic, two alert
windows are displayed:

1st. "An error occurred during DirectPlay Voice setup.
The error code is 0x8004005."

2nd. "Windows cannot execute DpvSetup.exe, use
Add/Remove
Programs control panel to install."

There is no obvious method of installing this component
through the 'Change or Remove Programs' button or
with 'Add/Remove Windows Components'

I did find a Microsoft article on their Support &
Troubleshooting page when I did a search on the
phrase 'dpvsetup.exe':

282882 - Error Message: Windows Cannot Execute
DPVSetup.exe, Use Add/Remove Programs Control Panel to
Install

This was exactly the error message I received but when I
tried the fix suggested in the article, (i.e., the
correction), I went into the Sounds and Audio Devices
Properties, chose the voice tab and hit the Advanced
button under Voice Playback which opens an Advanced
Audio
Properties window. The article recommends: "On the
Performance tab, move the Hardware Acceleration slider
at
least one position to the right."

My tab is already as far right as it can go.
I have updated the directx to 9.1
Any Suggestions?

You should be able to R.click the speaker by the clock,select,open volume
comtrol,options,properties,chk recording from playback,chk the microphone box,
and use it.One other way,open messenger,options,select tuning wizard,
this chks speakers and microphone also.
