Im using an Audigy (or Audigy 2) sound card and am not getting a flat response in the self test. What is the problem?
The default setting of the Audigy mixer has the Line-In signal playing back through the Line-Out. This places the system in a hard wired feedback loop when you patch the Line-Out to the Line-In for testing purposes. Depending on the level settings, the system may oscillate of just give a bogus frequency response. Fortunately the fix is quite simple. You just need to set the mixer so it does not route the Line-In signal to the Line-Out. The details are included in the Audigy setup file below: http://www.trueaudio.com/downloads/audigy-setup.pdf Also, make sure you review the Quick Start in the TrueRTA Help Topics.
