audio/mocp only for root user ?

[Elric <elric%anche.no@localhost>]

Hello there!
I've just installed NetBSD 4.0.1 with pkgsrc-current on my laptop
and i've installed audio/mocp from pkgsrc.

But it works only if ran as root user.
Otherwise, i get this error: 

elric @ melnibone $ mocp
Running the server...

FATAL_ERROR: No valid sound driver


FATAL_ERROR: Server exited

elric @ melnibone $


How to allow normal users to run mocp ?


Thanks,
Elric
