Wow. Thanks for the replies everyone. I didn't know what to expect.
I completely understand why PA doesn't work (well?!) with pass-through....
so my question is now.
If I am to keep PA installed and configured (it's now part of my Linux
distro and would like to keep things as "vanilla" as possible)..... what
steps can I take to have PA pass unaltered data through to my digital out ?
(I understand I will not have sound mixing, or multiple applications able to
use the card at once -> basically I would lose all the benefits of PA.....
but in order to stick with what my distro offers, but also to get what I
need (encoded formats passed unaltered to digital out)..... what can I do?)
