JUST PURCHASED A TASCAM US 122 UNIT AND IT WORKS FINE,,, GREAT UNIT BUT THERE'S ONE THING PUZZLING ME AND THAT IS , WHEN I GO TO THE SOUND AND AUDIO DEVICES SECTION AND IN THE AUDIO TAB MID WAY DOWN THE IN THE SOUND RECORDING SECTION I NOTICE THE VOLUME AND ADVANCED TABS ARE NOT PRESENT, WELL I MEAN THEY RESIDE THERE BUT THEY ARE BOTH NOT HIGHLIGHTED AND I CANNOT ACCESS THEM FOR SOME REASON,,,,IS THIS NORMAL ,,, THE DEFAULT DEVICE IN THERE IS MY UNIT AND THAT IS US-122 A-B SO EVERYTHING SEEM NORMAL ?,,,,,

2ND QUESTION IS ,,,, THIS UNIT NOW BECOMES MY SOUND CARD IN INCENSE RIGHT? FOR RECORDING AND PLAYBACK, AND I DONT HAVE A PROBLEM WITH THAT, SHOULD I DISABLE MY ON BOARD SOUND CARD DRIVERS OR LEAVE THEM ?

THANKS IN ADVANCE FOR ANY COMMENTS
