Hello, I've recently purchased some cheap budget recording equipment just to lay down some demos and what not. I have the Lexicon Alpha, Cubase LE5 that came with it, and a dynamic mic. I plug the lexicon in and turn up the line 2/mic channel, I hear a faint high pitch ring. I plug in the xlr for the mic into that channel and it gets worse. I am running Windows 10 on my laptop and have an old desktop with XP on it. On my windows 10 machine the ring only happens when I open up certain software like Cubase, audacity and even my sound recording properties. The XP desktop is a constant ring. I am not looking for a fix to the problem on my Windows 10 machine as I realize it probably isn't supported and how cubase keeps crashing and kicking out my interface.
