</div>No, it's new as of Lucid. The origin of this change is in Debian.<br>
<br>

<br>
Ask the Debian packagers. Probably because it complies better with<br>
conventions. Don't ask me which conventions, don't have the faintest clue ;)<br>

<br>
</div>Make your changes in /etc/security/limits.d/audio.conf to prevent any<br>
future problems.<br>

</div>Yes, concerns all cards. It's a complete rewrite afaik.<br>

<br>
</div>No idea, haven't used/tested the new Juju stack yet, afaik this is not<br>
necessary anymore. But then it wasn't required with the old stack<br>
either, you'd better use the audio or video groups for that.<br>

<br>
</div>modprobing and chmodding isn't necessary at all when you use the Ubuntu<br>
Studio Controls or add the raw1394 module to your /etc/modules and<br>
create a /etc/udev/rules.d/50-raw-firewire-permissions.rules manually.<br>
