You're not alone. Sadly as you're finding out, that is the state of such
applications. PulseAudio being the most widely used will probably
be the easiest to setup and find answers when you run into trouble.

On my laptops I disabled the pulseaudio use flag so none of my applications
is using it (except Bluez) but I keep it installed and running for bluetooth
audio. That way it cannot screw things up (except bluetooth audio but that 
doesn't work without it anyways). Yours would be a similar use case.
