Can you still reproduce this with pulseaudio 5.0?

If so, can you try disabling system mode? Upstream actively discourages
its use, so unless you have a compelling reason for using system mode
you should probably disable it.

This might be a problem because you have module loading disabled, which
could cause problems for alsa interaction.
