My unit won’t monitor audio from my iPad via usb-c. It was working about 3 updates ago, but since then, I am not able to hear any audio from my iPad via USB-C from my SP. I have the EXT SOURCE button on. I’m using Apple USB-C cable(s). Anyone else experience this?
Hi! Welcome!
Try holding SHIFT and pressing EXT SOURCE and see if you have it bypassed. Should be able to see input volume here too, but this value might be for external inputs, not USB.
While here press in the value knob to make sure you’re not on some input FX like the vocoder and it’s expecting MIDI notes with sound to play.
Next try your settings in the utility menu by holding SHIFT and pressing pad 13. Turn the third control knob to page over to the OTHER tab and check your settings there. Maybe it’s not routed right or something.
Also might sound redundant and dumb, but check your volume on both devices and any audio cables you’ve got plugged in. Sometimes things might look right, but aren’t quite clicked in enough. A lot of my problems have been this.
I hope this helps!
If not, this place has a lot more skilled and helpful people. We’ll figure something out.

Not sure if it’s the same thing, but there was an issue stopping it to work on the P-6, but there was a setting to get around it. Maybe @NearTao has the info you need?
Can you roll back the update to check its not the appliances or cables.
shift-EXT SOURCE:
Routing options are ExtIn and Mix. Tried both. No luck. Level is 127.
InputFx is on Scatter (nothing requiring midi)
You mentioned going to shift-13 (utility) and checking “OTHER”. I’m on firmware version 4.0.7 and not seeing an OTHER tab. I do recall seeing that on earlier versions.
The closest thing to that I can see is going to the SYSTEM menu and GENERAL tab. There I see a USB In option that is set to LineIn.

I suppose I could if it comes to this. Would need to look up how to do.

Honestly, this sounds like either a cable issue (you may be using a charging cable, not a data cable… unlikely but worth checking), or a iPad audio routing issue.
You should check what audio interface your iPad is sending data to. If you’ve played with AUM (or other apps) that let you do split audio interfaces, it’s possible that your iPad is not sending audio over USB-C and may be sending it someplace else.
In the latest iPad OS, you can check this when you do the top right swipe down motion on your iPad while it is connected to the SP404 mk2. Depending on your settings you’ll probably see the “Now Playing” bubble, this will have a little “output” icon that may have a speaker, headphones, etc… push that.
You should then open up to device settings that will say “iPad Speaker”, “SP404 mk2”… etc… or something there about. Anyways, make sure it’s on the SP404 mk2.
Beyond that, I’d probably need more information to see if there are other things that come to mind.

BINGO!!!
I do use AUM, GarageBand, and a few other audio apps on the ipad. That swipe-down from the top right and setting the ipad audio out destination did it. I’d not seen that setting before!
Thanks SOOOO much @NearTao and everyone else! SOLVED!

For others that are curious…
What has likely happened (and why I even know about this) is that AUM has an experimental feature (at least for the last iOS release) that allows you to use a USB device and your headphone jack as outputs. The reason this is cool is that it allows you to use the audio output for your iPhone/iPad to get audio out, and setup a proper loopback device between your iPhone/iPad with something like the SP404 mk2 without getting a feedback loop.
Is this awesome? Absolutely… does it bork your audio out settings… mysteriously also Absolutely.
Glad I could help!
