I managed to make sound WORK the following way:
Dockerfile

user group audio

RUN usermod -a -G audio developer

fancy alias

RUN echo 'alias starcraft="wine '"'"'~/.wine/drive_c/Program Files (x86)/StarCraft1161/StarCraft.exe'"'" >> /home/developer/.bashrc

Launching it:
docker run -ti --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v /dev/snd:/dev/snd -v /etc/machine-id:/etc/machine-id -v /run/user/$uid/pulse:/run/user/$uid/pulse -v /run/dbus/:/run/dbus/ -v /dev/shm:/dev/shm -v /var/lib/dbus:/var/lib/dbus -v ~/.pulse:/home/$dockerUsername/.pulse --privileged --security-opt seccomp=unconfined broodwar wine /home/developer/.wine/drive_c/Program\ Files\ (x86)/StarCraft/StarCraft.exe
