Did anyone answer to the member question of what if the rtcdll file shows in different locations? In my XP, I see the file name in 3 folders. And one of them has a different file size from the other two. Also, I see instructions referring to pre Win XP versions as well as Win XP pro. How about the Home XP. What file version does Home XP need? I am ready to bang my head against the wall not getting the sound to work after more than a week of trying.
