Hello everyone.  My name is Dan and I am new here.

Ever since I upgraded to a new machine and have  been a Windows Vista user, several features I have been used to in Windows XP and prior have disappeared, when of course we would all expect more features!  Or so I thought.  This particular issue seems to be caused by a hardware and software conflict on my machine.  With my current driver I can only view one audio control slider in the mixer, the master volume ("Speakers/Headphones").  What I would like to do is control the volume of my line-in device and the microphone in real time playback, but both of these are only available to me for recording.  In the past I have been used to these being in the mixer, easily accessible from the system tray.

Any ideas would be appreciated.  I have tried many different methods to fix this, such as reinstalling the driver, trying different drivers, but nothing has come through.

Thanks,
