Virtual machines are known to have broken sound on OpenBSD :(
There's a experimental port of sndio to linux, it seems more
reliable for testing audio-specific bits:

wget http://www.sndio.org/sndio-0.0.3.tar.gz
tar -xzvf sndio-0.0.3.tar.gz
cd sndio-0.0.3
./configure
make
sudo make install
sudo ldconfig
sudo mkdir /var/run/sndiod
sudo useradd -r -g audio -s /sbin/nologin -d /var/run/sndiod sndiod

Then, stop any audio program (to release the hardware) and run:

sudo sndiod -dd

If you think sudo is scary, all this stuff can run as regular user
as well, provided that mplayer uses the right -L, -I compiler
options and LD_LIBRARY_PATH environment variable. At this point
mplayer is supposed to work with sndio.

Then kill sndiod process, restart your apps, and uninstall all
files:

sudo make uninstall
sudo userdel sndiod
sudo rmdir /var/run/sndiod

Let me know if you need more information. And thank for your help
for the ao
