By the way, this confusion is only going<br /> to get more intense at release time (less informed / technical users).<br /> Could we include some kind of note informing users about this? Why not a<br /> &quot;RealTime kernel help&quot; item in the Audio Production menu, redirecting to<br /> the wiki page?<br /> <br /> Good day,<br /> <br /> -- Ronan Jouchet<br /> &lt;/pre&gt;<br /> <br /> {{Autor}}, setembre 2010</div>
