You can use whatever audio subsystem you like as long as it can hook up to the interface that BlueZ provides. The Media API itself hasn't been designed for any specific audio subsystem as such, but PulseAudio support for it was developed in parallel so it's what probably works best right now. And as I said, if you really need something else, such as ALSA user space plugins, feel free to take on the effort to port them to the Media API. The only reason they're about to get dropped is that no-one has shown the interest and resources to port them over and it doesn't make sense to keep maintaining two parallel API's (the old unix socket based and the new D-Bus based Media API). Btw, I also hope that you've done some proper study to conclude that PulseAudio doesn't suit your needs and are not just going on a "hunch" about it.
