Hi Colin Thanks for information. we were using an old kernel which doesnt have proper udev support (something like that I come to know from our kernel team.. :( ), then I migrated to latest kernel and now module-udev-detect is built getting loaded along with other modules :-) Next.. I am trying to plug-in/out accessory headset , I guess it should reflect in pacmd list-sinks or pacmd list-sources? but I am not sure, how to view the updated list of sinks/sources after plugin/out ? also , you mention one comment on my <a href="http://default.pa">default.pa</a> that .. "load-module module-alsa-sink device=hw:0,0" "OK, so here you've modified the <a href="http://default.pa/" target="_blank">default.pa</a> file for your system. You shouldn't have to do this. It implies a static configuration that obviously won't work with hotplug by itself...." is this affecting ???

It's just one module and it should be loaded at PA startup and should just sit their waiting for information to come in from udev. It should not be reloaded when you plug something in. Youy say it is not getting loaded? Does it exist on your install? Did you manage to build PA yourself but without udev support? If so, please see the very big warnings that result when you try to configure PA like that! It very clearly warns you when you do not build with udev support! Are you building your own PA or is it a distro? What platform are you on? Can you post the result of "pacmd ls".

So udev-detect is attempted to load here, but only if it exists. If the module does not exist, then I'd suggest you need to look at your Pulseaudio build process or package to work out why. <div><div></div><div class="h5"> Col -- Colin Guthrie gmane(at)<a href="http://colin.guthr.ie" target="_blank">colin.guthr.ie</a> <a href="http://colin.guthr.ie/" target="_blank">http://colin.guthr.ie/</a> Day Job: Tribalogic Limited [<a href="http://www.tribalogic.net/" target="_blank">http://www.tribalogic.net/</a>] Open Source: Mageia Contributor [<a href="http://www.mageia.org/" target="_blank">http://www.mageia.org/</a>] PulseAudio Hacker [<a href="http://www.pulseaudio.org/" target="_blank">http://www.pulseaudio.org/</a>] Trac Hacker [<a href="http://trac.edgewall.org/" target="_blank">http://trac.edgewall.org/</a>] _______________________________________________ pulseaudio-discuss mailing list <a href="mailto:pulseaudio-discuss@lists.freedesktop.org">pulseaudio-discuss@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss" target="_blank">http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss</a> </div></div></blockquote></div>
