how many LV cables in SCH40 conduit?

[lleo]

So I learned about NEC conduit fill ratios and related calculations, but as simple approximation by PROs on this forum:
 
- how many CAT6 cables max. in 1 1/2" SCH40 ENT conduit from basement closet to attic straight vertical run (8')?
 
- what conduit size from basement closet to attic straight vertical run (8') for #20  22/4 CL2 security wire?
 
- what conduit size for #16 12/2 CL2 speaker wire from basement closet to attic straight vertical run (8')?
 
assuming only same type of cable in conduit.
thanks!

As many as can fit.

Conduit fill does not apply to LV.
 
I would have to verify the speaker requirements as I believe this changed a cycle or two back as far as separation goes.

Thanks, DEL!
I was planning to keep speaker wire in a separate run

Put in bigger than you think you will need.  That way you can add a few more later.  And adding some needs more space than putting them in at first because they cross over each other.
