It does not produce any sound through qemu but it generates an output on 
stdout:

oc@NetBSD:/home/oc$ audiocfg test 1
1: [*] audio0 @ eap0: Ensoniq AudioPCI
       playback: 2ch, 48000Hz
       record:   2ch, 48000Hz
       (PR) slinear_le 16/16, 2ch, { 4000, 48000 }
  testing channel 0... done
  testing channel 1... done

So this is a qemu issue. I spent hours on the #qemu channel on OFTC but 
nobody (read: the paid developers) have come out with anything sensible.

It goes without saying I'll have to ditch qemu.
