It's currently impossible to build both the ALSA and PulseAudio audio plugins[1], which make it hard for distro to ship both plugins.

As a result of this, most distros seem to ship only the PulseAudio plugin, and users without PulseAudio get no QAudio support at all.

This was reported on the Archlinux bugtracker[2] and Debian Issue tracker[3] (QTBUG-29742 is somewhat related).

Would it be possible to allow for both plugins to be compiled and choose at runtime which one to use ?
