I suppose you are not showing a large speaker icon in the hidden icons on the Taskbar?
I run the normal driver and it works fine after the build upgrade. I once looked for an answer as to why two drivers, but that info seems to be shrouded in mystery...possibly additional functionality in the second one. If you go through the extremely long and out of date thread, you may find some sort of answer.
