I'm completely new to this, so be kind to me please.
Ubuntu studio 14.04
Komplete Audio 6
Rode condensor mics.
I've found this link which says it should "just work",
http://lists.linuxaudio.org/pipermail/linux-audio-user/2013-October/094733.…
but I can't seem to get response from the inputs (microphones). I did
manage to make Yoshimi talk to the KA6 via Jack but that isn't what I need.
Ultimately I want to be able to simply record stereo microphones into
Ardour or Audacity. Preferably Audacity because I'm familiar with it.
I suspect that I'm not configuring Jack connections correctly but don't
know enough about it to see what the problem is.
I've set the interface in qjackctl settings to the KA6.
The KA6 never shows up in the volume control panel in the way that a USB
headset would. The KA6 does show up in both input and output sides of
the qjackctl ALSA tab.

you set both the Input Device and the Output Device.
Works fine for me on debian.

I am not sure so I may be asking obvious questions. Does the KA6 have
phantom power turned on (48v switch on the back)? Does the KA6 show levels
from the mic(s)? Are there level controls on the KA6 (yup)? Are they up?
Next: aplay -l and arecord -l says what? Ah someone has done that already:

Well sort of. It does say "set the connections in qjackctl". I am not sure
what that means.
In qjackctl in setup-Settings There is an interface box. The intuitive
thing is to click the V beside and pick one... don't do this. Instead
click on the > box and choose hw:K6. This should give 6 in and 6 out. If
not... you will want to see if using Input Device and Output Device works
better. I am not familiar with the K6 so I can't say. It should not be too
hard to connect the input directly to the output to see if there is sound,
but I prefer to start meterbridge and connect there so I know there is no
hw monitor stuff giving me false info. Also, in a terminal, run alsamixer
and make sure the capture levels are up. Or switches need to be set. There
seems to be some capture switches.

So that is outputs.

headset would. The KA6 does show up in both input and
output sides of the
qjackctl ALSA tab.
The ALSA tab is MIDI i/o (yes there are two of them for two kinds of MIDI)
You want to see i/o in the Audio tab. There should be system on both
sides. and when expanded there should be 6 on each side.
Just sort of a splatter of ideas....

on the back)?
The Rode website says that this mic doesn't care either way about
phantom power, but in any case I've tried it both on and off. Apparently
some mics can be cooked with phantom power!
Does the KA6 show levels from the mic(s)?
I get a "flashing light" level indicator on the KA6 when I test the mic.
Are there level controls on the KA6 (yup)? Are they
up?
both mic gain and master are set at 12 o'clock. (Edit: they don't seem
to alter the record levels - odd?)

I had never heard of meterbridge. I did <$ jack_lsp> and it gave me
"system:capture_1" etc etc, but when I started meterbridge I got no
signal, even though the level light was flashing on the KA6 so there is
still a problem.
.... and connect there so I know there is no hw
monitor stuff giving

Alsamixer proved interesting. I've never used it before. First I had to
select the KA6 using <F6: Select Sound Card> and then I'm presented with
an arcane screen. I messed around by tabbing through "monitor control
front" "monitor control rear" and "monitor control 1" and typing
<m> at
each position. That changed the "MM" (mute?) in the box above each item
to "00". This seemed to create some sort of magic because now I'm
getting a vu-meter reading on <$ meterbridge system:capture_1>. I can't
understand why altering the monitoring should make the input work, but
apparently it does. Pressing <F4> in alsamixer tells me that "this
device does not have any capture controls". Very odd.
This seems to be the answer to the problem.

Generally a condensor mic needs power, either batteries, phantom or a

Right, two mics(1,2), two lines(3,4) and two from s/pdif(5,6). The outputs
are similar. Perfect.

Ya meter bridge is kind of funny, the *.desktop file starts it with two
meters that are supposed to be connected to alsa_pcm:playback_1 and 2 so
on my system that means they are not connected to anything. But it is a
handy signal indicator for trouble shooting when not using it for
metering.

many other mixers deal with psuedo/soft controls.

Yes M is mute. I have gotten sound out of things using alsamix when
nothing else works. It shows up interdependancies rather well too. (where
moving one control affects another - I have one where muting one channel
mutes three and unmuting only unmutes one)

Probably routing would be a better word than monitoring.

Quite common actually. You control the level with the physical controls on
the box... although it seems with this one the volumes that look like
output may affect the input. The manual was not that clear to me.
One wonders
which volume control pannel that is, and where within that.

I think it may be a soft level if alsamixer doesn't show it.

No, just pulse itself.

It is just nice to see someone else enjoy linux audio and not go away
frustrated.
