That shoudl work.

New machines are able to use headphones & internal speakers at the
same time. WIth USB audio, you should be able to play different songs
to both... so no, I don't think kernel should make a decision to just
take over internal sound...

...that said, yes, I believe ALSA is one of most problematic
subsystems. (The next one is 3d graphics)... and yes, it should be
fixed. Going to regular devices (and not alsa card names) would be
welcome first step.
