ESD - sound is to slow

I can not figure out how to speed up the sound when playing wave files through ESD. I played around with the esd options "-b" and "-r" and they don't seem to have any effects. To get esd working I used the "-d /dev/audio" option since using /dev/sound causes an invalid argument:

$ esdplay E_logout.wav
- using device /dev/sound
/dev/sound: Invalid argument
/dev/sound: Invalid argument

A guy from the local LUG group informed me that /dev/audio is not a generic sound device and it accepts only .au files (8-bit mono raw files running at 11050 KHz). No matter what I throw at /dev/audio, it will always attempt to interpret it as if it's such a sound stream. I guess I was on the wrong track with /dev/audio.

He and some other places recommended using /dev/dsp but OpenBSD doesn't have this. Instead I found /usr/local/emul/redhat/dev/dsp but that also gives me an invalid argument error (since it's linked back to /dev/sound).

I'm trying to run Enlightenment and besides the sound everything is working fine. It would really be nice to get the sound working as well. Does anybody have any tips, hints or solutions?
