First post and ready to b*itch a bit.

I'm running Notion 4 on OS X (Lion, latest updates) and noticed that each time I fire up Notion, all audio on my system goes to mono and the change also affects other software running at the same time (like iTunes). I don't know if this is a common issue or just my cheap Akai RPM3's drivers that are causing it (I haven't tried with the OS X default drivers).
Anyone else?
