Playing any of these sample
tunes using
eagleplayer (here is the
key, now is freeware) or
delitracker using 100% stereo separation doesn't seem to work. Try those players I linked and pitch channels slider to left or right (the slider is the in the main gui(s), below or above volume slider. For testing, it's *better* if you listen the tunes with headphones): you'll always hear the other channel lowered. I'm pretty sure eagleplayer and delitracker aren't supposed to do any sort of channels mixing. My sound card isn't doing any mixing: if I do some tests with other windows apps (iTunes), I can listen to both channels fully separated.
Changing 100% to any other value in WinUAE sound config seems to do something, tough. But 100% *isn't* really 100%. Ask me if you need more details. WinUAE version tested: 1.6.0b28 (btw I probably noticed this with previous versions too).
