@alciregi is right, pulseadio-libs is a subpackage of pulseaudio and therefore does not have it’s own repo.
Each repository on src.fedoraproject.org/rpms represents one source RPM package. But often multiple binary packages are build from one source package, so the user can for example install a library without the associated application etc.
But i"m not sure what you’re trying to do here*. Building the package yourself is unlikely to fix your problem - you’d just end up with the same package as in the repositories, but built locally.
*Apart from just trying stuff out - I fully support that .
I have a complete build log for pulseaudio.git
I’m looking closer at the log file for: pulse.c which output the error:
“ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection refused”
If I find pulse.c, I’ll look through the source code for the error.
