IIRC code doesn't really apply to low voltage stuff, or it's a lot more
lenient if you're not running line voltage.  Mostly for materials to make
sure it doesn't spew toxic gases when it burns.  I think it mostly depends
on your codes inspector.

But yes, you cannot mix line and low voltage.

The other big advantage of conduit is that you're much less likely to get
a cut cable from a sheetrock nail.

You are an adult when you realize that everyone's an idiot sometimes. You
are wise when you include yourself.
