I was talking about Stereo Out for Speaker (when not in call). Sorry to be
unclear. So, how does the "simple" slider correspond to Bypass and Headphone
in the advanced view? Or are those things all different controls? Moving the
"simple" speaker slider seem to change Bypass and Headphone, but at different
rates for different ranges of the "simple" slider. When I max out the simple
slider (to 101), bypass and headphone are at 100, but at lower simple slider
settings they change very non-linear.
This was probably discussed numerous times. But your visual application makes
the channels easier to control and I finally feel that I have a chance to get
the volume I want during calls. It's all so confusing.... What's a good place
to learn the relations between all the channels/controls/bugs that make sound?
