this has always been a plug and play device for me
all of a sudden jack does not recognize it from the usb port
it is recognized by alsa according to cadence but when i check qjack it is not there and it is defaulting to the soundcard
i think i may have recently updated my low latency kernel and that could be the issue?
any ideas on solving this? it just seems strange that it will run if i choose alsa but not with jack

Re: native instruments komplete audio 6 jack issues
verify that the text files /etc/security/limits.d/audio.conf
and /etc/security/limits.conf
both end like this:
@audio hard rtprio 99
@audio hard memlock unlimited
@audio hard nice -19
(The text formatting, -not the content- will be a little different than the above
due to web text weirdness)
Try this: unplug the k6
change periods-buffer in qjackctl from 2 to 3
reboot
plug in the k6, and start qjackctl
then look at the end of the text logs in /var/log
for dubious related messages
Also, google the phrase 'alsactl init'
which command may reset something the update nuked.
Also command # sudo modprobe snd_seq
Some kernels errantly fail to load it.
And uninstall pulseaudio. You can always reinstall it later, or better to have an external drive
with a pulse enabled distro if needed for skype or home theater etc
Good luck!

Re: native instruments komplete audio 6 jack issues
You can always try typing "hw:K6" in the interface field, in qjackctl setup.when i check qjack it is not there and it is defaulting to the soundcard
However, it should appear if you click on the little horizontal arrow on the right
(not necessarily in the drop down menu).
I think the error message
happens because you selected 2 at "channels I/O". Leave that as default.ERROR: ALSA: cannot set channel count to 2 for capture
