I have a IBM Intellistation running 98se.It is missing extrac.32.exe mfc.30.dll,mfcvia32.dll,mfcans.32.dll,mfco30.dll,oleacc.dll,Would any of these missing files affect that sound controls??This machine has no sound or the sound test button is greyed out . I've reinstalled updated, etc. the drivers thanks for any replies.gregg
