Pan issue sound disappear (alas mixer)

I have a m audio fast track c400, works fine with Linux, the only issue is when panning I notice the sounds disappear when being panned and also they become lower in volume and it does to multiple tracks and individual ones, I can fix them but it messes up other tracks when I use the ALSA mixer to adjust the many outputs etc my sound card seems to have in ALSA compared to the built in sound card my laptop has, is there a way to fix this or do I have to use a Dac that doesn’t show many outputs and inputs in ALSA that can mess with the stereo imaging of tracks
