Yes we can :-)
Either use a wrapper (like arts under KDE, esound...), or use virtual 
For exemple, here is what I put in my /etc/sysctl.conf:
Now, I have 4 channels for sound:
/dev/dsp (= /dev/dsp0.0)
Now, you can configure your applications to use either one of those. I use 
/dev/dsp0.0 for arts (so every application that can use arts; there's a lot) 
can have simultaneous sound. I use /dev/dsp0.1 for realplayer, /dev/dsp0.2

Well, everything under X is much slower under FreeBSD than under Linux or 
Windows (any flavor)... at least, this is my experience.
I think (please feel free to basically, for today jobs (workstation, small 
workgroup servers...) Linux is faster, but in high load server tasks , 
FreeBSD is the fastest OS I've ever seen (OK, I haven't seen a lot, but 
Nevertheless, I use FreeBSD on my workstation.

Best regards.
