seems a bit dangerous -- should probably add NOTREACHED()

[tommi (sloooow) - chröme, 2013/03/01 11:29:29]

Can we make these methods pure virtual?

[no longer working on chromium, 2013/03/01 16:44:33]

Done.

I make it pure virtual to for the developer to implement their own
GetDefaultOutputStreamParameters on all AudioManagers
