After installing Service Pack 2 (on top of Service Pack 1) onto my Vista machine, I now seem to have a loudness problem with all the audio devices on my PC. Even with the knob turned all the way up on the speaker amplifier and even after adjusting the volume levels in the control panel for the sound cards and applications there....even with everything cranked up, the system only gets moderately loud. I used to be able to make it shake the walls if I wanted to. I would expect a hardware issue, except that it affects my USB headsets as well and it started happening immediately after SP2 was installed.
Any thoughts or suggestions!? I seem to remember reading that SP2 somehow affected audio drivers, etc.
