Just in case you haven't done this right click on the volume icon in the lower right hand side of the bottom toolbar on Win 7. If there is no volume icon there let me know.

Click on system sound events.
Click on recording, your input device (in the pic I have Line-In clicked) then properties.

Click on levels and set the input level.
Click on apply then OK.
Click on the volume icon and look for an output level menu. Mine is under audio devices/playback/speakers/properties/levels.
Click on apply then OK.

Start BiaB and see if that helped.

Depending on your sound card you may see a different menu(s). Just search for a recording input levels, output levels and sometimes a MIDI recording levels.

If you have already done this then I apologize for the redundancy.

If I knew your sound card I might be able to help you better. You do not need a new computer. With enough information and trial and error we can and will find the problem.

My goal this weekend is to move just enough each day so that no one pokes me to see if I'm dead or not.
