Did you try the 2.6.22.10-1.rt9.1.fc8.ccrmart kernel ?<br>It works much better for me than the 2.6.23<br><br><div><span class="gmail_quote">2008/1/23, Florent Berthaut <<a href="mailto:hitmuri@no-log.org">hitmuri@no-log.org

<pre>USB-Devices often perform much better with -n3. Furthermore I would try<br>to eliminate any flag, that is not absolutely needed such as:<br><br>/usr/bin/jackd -R -dhw:1 -dalsa -r44100 -p64 -n3<br><br>BTW: this would compute to around 4 ms latency - is that good enough for
<br>you?<br><br> </pre>

Okay, i had forgot to turn off the system "bips" and esd (it reduced
the number of xruns)<br>
And yep with -n3 i 've got even less xruns and it seems they're not
audible. <br>
I don't know if the latency is low enough though, i'll test this
evening with my drum pads.<br>
<br>
Thanks everyone , it's really great to get so much help so quickly. <br>

Argh, actually i still have audible xruns. And i don't think i'd be
able to play correctly with a higher latency anyway...<br>
Think i'll have to get back to ubuntu studio ... :( <br>
