My Falcon's DSP has always been a bit stubborn when it comes to audio input processing. Occasionally it works with both channels flawlessly, but frequently the right channel looses signal. The input signal and connections are tested to be functioning fine and there are no connection problems. I suspect the DSP electronics might be causing the problem. The OS is patched with FPATCH2. I have a friend that experiences similar problems on his machine when using WHIP! and Audiotracker, so it appears not to be isolated to my machine.
Playback of samples in games and demos do not exhibit these problems, only "live" audio processing through the Falcon audio input jack.
