Hi,
+
+'Twas brillig, and Sascha Schneider at 21/12/10 21:06 did gyre and gimble:
+> Wiki updated http://www.mageia.org/wiki/doku.php?id=soundstudio
+
+Sorry I've been a little quiet of late. Email backlog + work commitments
++ $EXCUSE.
+
+I've added a comment to the wiki page about the suggestion of editing
+/etc/sysconfig/pulseaudio. This file is more or less outdated now. I
+should probably tidy things up and remove it.
+
+Nowadays we use "Sound Profiles" which should be an ideal scenario to
+allow you to package up various tweaks and tricks with symlinks and get
+them activated automatically when the user switches to a different sound
+profile.
+
+The sound profiles are based on the alternatives system.
+
+See: update-alternatives --display soundprofile
+
+Ultimately you can read the current profile.conf here:
+
+CONFIG=/etc/sound/profiles/current/profile.conf
+
+
+But to create a new profile, just the pulseaudio package. It's basically
+just a matter of creating a folder /etc/sound/profiles/myprofile
+
+When you register it with the alternatives system you give it a
+priority. I would suggest that if the package containing the soundstudio
+profile is not installed by default then it can have a higher priority
+than the pulseaudio one, and thus automatically activate when installed.
+
+Things like udev rules and such like could be installed by the package
+but only activated when the profile is actually active (e.g. via
+symlinks) - you may want to put dummy udev rules in place for the other
+profiles too to make the symlinks always resolve.
+
+Also disabling libcanberra (by exporting CANBERRA_DRIVER=null) would
+also be sensible - event sounds and such like are obviously highly
+pointless/evil when doing pro-audio work! Currently the driver is
+changed via this mechanism for a pure alsa profile (CANBERRA_DRIVER=alsa).
+
+HTHs
