Ive had this happen 3 times now and i have to reboot the KPA to solve it any once else had it???
Here is what happnes. Im scrolling through profiles and then suddenly the tuner appears. I press exit and all my sound is gone what ever profile i select there is no sound at all. i have to reboot the KPA to get sound again any one else had this. Im on latest firmware 
I've seen it twice. I think I read somewhere on here to just hit the 4th soft button for "pedal volume to max" or something. I tried that the second time and it got me out of it.

Cool ill try that hopefully CK and crew will address this bug in the next firmware 
It did it 4 times to me.
This kind of happened to me at last rehearsal and couldn't figure out what was going on. But I still had sound, just crappy unprocessed sound. And it seemed to directly affect the patch, because I would move the chickenhead knob from browse to tuner, back to browse, but then as soon as I stepped on PC001 the tuner would pop up. Restarting the KPA made everything right again, but that was very stressful--can't have it happen in a live setting.
A workaround for this would be to disable tuner When volume = 0
you do this buy pushing the Rig button go to page 3 volume pedal settings set the range To - 4.9
This will also prevent the volume pedal from going to tuner at heel.

Happened to me last night, and I stumbled on this solution by accident.
Last night, I had the same problem - KPA goes in tuner mode - no tone - switched from browser mode to tuner mode to browser mode and klicked a few buttons - tone is here.
This issue on stage - makes a lot of problems. Hope the Kemper Folks will fix it soon.

The tuner pops up in purpose, when the virtual volume pedal has been set to zero either by a connected expression pedal or by midi (a remote floor controller).
By nature, you will hear no sound due to that.
Additionally a message pops up in the bottom that volume is at zero.
Pressing Soft Button 4 will reset the volume to normal.
Please check, if a pedal has probably set the volume to zero.
The opposite is happening for me. I cannot get the heel to engage the tuner, even though the range is set to -5

CK my tuner problem has happened 3 times without any pedals connected at all

Same here. Nothing connected to the Kemper. Scrolling presets quickly and it suddenly in tuner mode.
Yep, same here. Every time pressing the right button on the Rig d-pad.

What foot controller are you using?
If its the FCB1010 you need to re-calibrate and I suggest when set the heel you leave it slightly forward.
Yes, I am using the uno4kemper FCB1010. You're saying after I change the chip (coming from Un0) I need to recalibrate the pedals? I think that might be true, because even with the pedal heel down and the setting at -5, I still hear a little something when I play.
Its easy 
holed pedal 1+5 down power up
Set pedal A to heel (Leave a little forward)
press up/enter switch.
set pedal A to toe.
press up/enter switch.
Set pedal B to heel (Leave a little forward)
press up/enter switch.
set pedal b to toe.
press up/enter switch.
Your done
I understand that you get this tuner window when switching rigs, but still hear sound.
Correct?
Does the tuner window say "volume pedal at zero" still?

No midi; no expression pedal connected?
Can you retrieve the sound by pressing soft button 4 then?
Have you ever tried it?

Yep nothing connected at all. Yes pressing the 4th soft button retrieves the sound as I tried this yesterday
