Dx9.0 install and dpv setup issues

hi in windows xp have error message unable to start dpvsetup. files are in windows not showing in registry and getting unclassified errors.

Background:

I use pc for fairly major installation of fsimulator x that has grown over a number of years and everything works fine.

Sound card is Realtek and has latest drivers installed.

I bought a record turntable that connects via USB in order to transfer collection of vinyl lps to mp3.

It came with setup disc and when I tried to run, after install I got error message unable to play dpvsetup and class Ids missing.

From control panel I opened sounds and checked settings, all ok, ran test on voice tab and got dpv setup error message.

Checked win32 for presence of dpvsetup. Definitely in file but doesn't seem to show in registry listings!

I then ran Dx diagnostics on graphics and on the graphics and network tabs I had error messages saying errors in registry and several messages along lines of unable to connect to various things.
Recommendation to reinstall directx which I eventually did.
I also reregistered dll files.

A small degree of success ! Now from the sounds menu when I try and test the wizard starts ( I guess that now dpv setup is recognised ) but further error message saying my sound card cannot play sounds which it obviously can as I was listening to it!

A check of registry values showed up several with "no value" in the address where I think you would expect a .dll ref.

So I completely uninstall dx9 and reinstalled but still have same error messages.


Basically my system plays music and sounds normally but doesnt allow recording from anything

how do I recover please

Already Tried:
tried to delete file via registry but it doesnt show under windows, system restore to previos date didnt work deleted direct x files manually and reinstalled direct x 9.0c same result ran sfc/scanow from Xp cd

 

Hello,
Just thought I'd update, have spent another few unproductive hours trying to sort this issue to no avail. It really seems to be something to do with the Dx registry entries, diagnostics still says on the graphics and input tabs that there are registry problems despite totally removing direct x and reinstalling latest 9'0c. I guess as over 150 have viewed this with no response that I may just have to put up with it!,

Would anyone have a listing of the correct registry entries re direct x for win Xperia that I could compare?

Best regards. Clive
