Yes, it should be filed as a bug on whatever sound test program you're
using, I think, as a segfault is just C (and its ilk)'s way of saying
there's a bug in how the application is managing memory.

Try testing it with some other application.  The driver's likely fine as
it's detected as an audio device.  Just to be sure, you should try it
with a different application though.
