Hello!<br>
<br>
I'm experiencing some weird issues with JACK. I got a new system the other<br>
day, and I'm tweaking it for linux audio only basically. My issues are:<br>
even when dsp load isn't even close to 100%, I get xruns. This only happens<br>
at lower latencies, but still. My setup is as follows :<br>
<br>
Kxstudio 12.04.2<br>
3.2 realtime kernel (tried lowlatency and generic aswell)<br>
Usb sound card Lexicon Omega<br>
Realtimeconfig quickscan shows everything green except cpu governors, but<br>
I'm pretty sure I don't have that on this system? It's an Intel i5 3570k<br>
desktop. Or maybe there's some setting in BIOS equivalent of cpu governors?<br>
If so that might very well be the problem.<br>
<br>

Hello Gabbe,<br>
<br>
You can check what governor is in use with:<br>
cat /sys/devices/system/cpu/cpu*/<u></u>cpufreq/scaling_governor<br>
<br>
And set it to a non-scaling governor with:<br>
echo -n performance | sudo tee /sys/devices/system/cpu/cpu*/<u></u>cpufreq/scaling_governor<br>
<br>
You can also disable it in your BIOS, it's probably called something like SpeedStep. More info: <a href="http://wiki.linuxmusicians.com/doku.php?id=system_configuration#cpu_frequency_scaling" target="_blank">http://wiki.linuxmusicians.<u></u>com/doku.php?id=system_<u></u>configuration#cpu_frequency_<u></u>scaling</a><div class="im">

I use JACK at 48khz 3 periods/buffer. I start it via falktx's Cadence.<br>
<br>
Any ideas about this?<br>

Please post the output of:<br>
cat /proc/interrupts<div class="im"><br>

Also! When I'm asking for help anyway... I connect my MIDI keyboard via<br>
MIDI in on my sound card, but that suddenly stopped working. The midi out<br>
from the sound card is present in JACK, but it delivers no midi. Any idea<br>
on where to start troubleshooting this?<br>
<br>

Did you try other USB ports? Or issueing a:<br>
sudo alsa force-reload<br>
Does that help?<br>
<br>
Regards,<br>
