I'm wondering about what sound spitting firefox plugin could it be that
forces you to use OSS(-wrapper).

I have installed following plugins that can make use of the sound
device (firefox 64bit):
* mplayerplug-in 3.50 (64bit)
* adobe flash 9.0.124.0 (32bit)
* realplayer 10.1.0.4216 (64bit)
* OpenJDK6 (64bit)

..and all of them use ALSA directly.

Just curious..
