They certainly do not use it by default and in a typical setup it is not activated by default. 99% of their users they will totally ignore this script and it will not be run. > But then in the Ubuntu forums there are many, many reports of people going > System > Preferences > Sound and then getting nothing but a message about > waiting for the sound system to start.

Like I said, they do not do that. They maybe did about 4 or 5 releases ago, but certainly not in any recent release. > Nonetheless, for now, your largest user base is probably on Ubuntu, and if > it's not going to work so well in system-wide mode, either Canonical or > Pulseaudio should work things out so it does, or else doesn't even try to > work that way. I really think you're reading too much into this. Like I say it's not enabled in Ubuntu by default. Only if users take specific action to enable this will it be used. >> In the default, per-user setup that we ship, PA auto-spawns, so exiting >> the daemon is generally not overly problematic (clients which support >> reconnect will do so automatically). > > I'm all for building stuff from source, but sound is such a complex stack > I'd worry about how much other stuff would need to be from source rather > than from the distro's packages in order to keep this stable as other system > components go through their upgrade cycles. I really wasn't advocating you build anything from source yourself. I'm just stating the recommendations of the upstream project. Ubuntu/Canonical/Debian provide the system wide init script for those few users that want it, but like I say it's not enabled by default. > Meanwhile is there a right way > to restart the daemon on any level at all under Ubuntu without having to > reboot?

Or does Ubuntu's > having started it system-wide the first time around mean there's just no way > to get there? I've said it before, but Ubuntu does not have it system-wide. They provide the init script but their default setup is to not run it system wide. "pulseaudio&" will just try to run PA and when it detects one is already running it exits. "pulseaudio -k" will kill the currently running daemon. Generally speaking PA will then just automatically start again due to it's auto-spawn capabilities. That said, after killing PA, you should generally run start-pulseaudio-x11 script again (it's done automatically at login for you) to ensure the correct X11 related modules are loaded into PA. >> I take your point re the "exit" command tho'.

Touch typing with keyboard short cuts is easy enough (we all know to hit ctrl+s all the time right???) :p Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mandriva Linux Contributor [http://www.mandriva.com/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/]
