It is set that way.

By the way, I tried setting to sndio, and even though sndio wasn't running,
It still had sound.

But virtual_oss still has the same firefox results (no sound). I have to
reboot the machine to get the sound back on FF.
Stopping virtual_oss and restarting FF is not enough.

I also had virtual_oss_ctl installed but, like you, I dont know how to use
