Oliver Baldwin-Marshall

Hi there, did anyone figure out this issue? I have tried everything already mentioned and haven't been able to fix it. The same as the original comment, I am getting vocal audio from the mic just fine but Cakewalk doesn't register any audio from my guitar being played through the mic. I know the mic and interface are functional because the interface shows that the guitar audio is getting through when it lights up. I have no idea how to fix this. Help?
