OK, so is the version that is running the distro provided one or your new one? Chances are it's your distro version and your self compiled version of PA are in some way conflicting. Can I ask specifically why you need to build your own version of PA and not use your distro version? You said originally you are developing a client application for PA. Is this the case or are you hacking on PA code itself? If the latter then you should really use git so that you can track your changes. If the former (you are just developing a PA client app), then just install your distros development package for PA and you should be good to go, avoiding any hassle. If you really do want to run PA and don't want to over write your distro version, I wrote a guide some time ago about running PA from git: http://colin.guthr.ie/2010/09/compiling-and-running-pulseaudio-from-git/ You also did not supply the pulseaudio -vvvv output that would have aided debugging, but hopefully we can short circuit all that if you are just developing a client app as you don't need to build your own PA for that :) Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mageia Contributor [http://www.mageia.org/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/]
