Anybody know why the buffer bias reading would drop across one channel when hooked up to headphones without sound. The right and ground channel only vary from no load readings by 3mv. while the left channel drops about 20mv.

With another set of headphones it is the opposite. Left and ground stay stay around 63mv, while the left channel drops about 40mv to 24mv. Also, DC offset shoot up on the Right channel, to 2.2mv. While the Left channel stays at under 1mv.
