The best way to test if your Linux setup is ready for audio, I think, is<br>
here:<br>
<br>
<a href="http://wiki.linuxmusicians.com/doku.php?id=system_configuration" target="_blank">http://wiki.linuxmusicians.com/doku.php?id=system_configuration</a><br>
<br>
Download the .pl file, make it executable, and run it in a terminal. In<br>
other words, in a terminal:<br>
<br>
wget<br>
<a href="http://realtimeconfigquickscan.googlecode.com/hg/realTimeConfigQuickScan.pl" target="_blank">http://realtimeconfigquickscan.googlecode.com/hg/realTimeConfigQuickScan.pl</a><br>
chmod +x realTimeConfigQuickScan.pl<br>
./realTimeConfigQuickScan.pl | less<br>
<br>
and study the results. My hardware is such that realtime kernel is not<br>
necessary, and I'm not sure about 'noatime' on the filesystems, but<br>
everything else it reports has been extremely valuable. AVLinux ran<br>
well before I did all the things it requested; after I did them, it<br>
began to run screamingly.<br>
<br>
There is a list of multimedia-oriented distros on that page, but some of<br>
the listings are alpha quality, no longer in existence, et cetera.<br>

<div><br></div><div>Since on a Linux system files are written to almost every minute, recording atime everytime an access occurs increases the disk I/O.</div><div><br></div><div>I need to know access times for some files so I don't quite like that.

<div><br></div><div>Such tests like to assume a lot of things, so I don't like those either. Anyway this isn't really a test, it's just a mockup a user put up because he was asking for something similar and realised there was no answer.</div>
