Comment 1 Daniel Berrange 2011-10-03 04:27:48 EDT

The depends on libpulse is *intentional* as PulseAudio is the default host audio driver we build for QEMU. 

* Fri Sep  4 2009 Mark McLoughlin <markmc@redhat.com> - 2:0.10.91-0.9.rc1
- Make pulseaudio the default audio backend (#519540, #495964, #496627)

Comment 2 John Schmitt 2011-10-07 16:35:52 EDT

I've taken some time to think about this.  

In this context, does default mean "mandatory"?  As far as I can tell by rpm -qil pulseaudio-libs, there isn't even a static pulse library.

Since libpulse is a shared object, you can know whether it's installed by what dlopen() returns.
