SP3 sound plus update problems

Since installing sp3 I get interrrupts and glitches on any music or other sounds I happen to be playing whilst using my pc or browsing. If a web page is loading the sound stutters whilst the page loads, if I open windows help or a folder full of lots of files the same again.

I have a soundblaster audigy card which has been functioning perfectly until loading this SP3 and it works perfectly again if I uninstall SP3.

The other irritant is that whilst SP3 is installed updates of any description from windows update will download o'k but then I get a message that some updates cannot be installed

[it should read all updates] there is no error code.

I tried autopatcher after getting fed up with trying this and it has no problem installing the same updates.When I return to windows update to doublecheck it does not select those installed updates for download.

I have now returned to SP3 for the second time and exactly the same thing is happening.

I've reinstalled latest soundcard drivers to no avail
