Probably (and I'll leave it to you to prove it ;-) ).
From your mail before, it looks like you have ALSA installed, but
the sndinfo output above doesn't show any ALSA devices. This
probably was caused by missing alsa-devel package in your system. So
try installing alsa-devel and do ./configure again.
In any case, make sure that no other program is using the sound
device before you start pjsua.
