Hi, I am using a Behringer UM2 on my Mac (OS Catalina) and all works fine with GarageBand, so I believe I have the UM2 set up correctly. But I can't get a signal into Jamulus, I'm sure I've set it up correctly - I can hear others! Can you help please?

Thank you for replying, and Vincenzo, no need for apologies :-).
I have tried all the available settings one after the other when the original ones I chose didn't work .
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Just to fill in some detail here are, what I hope, are relevant screen shots. You can see that a signal is present at the sound card but I can't get any green from Jamulus and friends say that they can't hear either the mic or bass.
If Garage Band is working, are there any clues that side? I'm not familar with GB, but might there be an "exclusive" setting it has? Is the device its using listed in the list you have in Jamulus?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I only mentioned GarageBand to suggest that the UM2 is actually supplying a signal into Mac that makes an App work.
As GB works, one more thing I have tried, is to install Blackhole and use that as the output for GB (instead of buit in speakers) and as the input for Jamulus. Still nada. But thanks Gilongo.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Sorry, what I meant was is there something different about the way GB is set up compared to Jamulus. But perhaps a better line of inquiry (looking at your screenshots) is to work out what you are trying to do exactly.
You mention a bass, so can we asume you want to connect the UM2 for vocals and the instrument input into Jamulus at the same time? If so, you need to set Jamulus Audio Channels setting to Mono-in/Stereo-out. You can then have your sound card with the bass on one input channel and the microphone on the other. The two input signals can be mixed to one mono channel but the server mix is heard in stereo.
Thre may of course be some other issue here, or perhaps your audio interface (are you using your internal one?) doesn't support this. But can you post a screenshot of what you see if you set the Audio Channels to Mono-in/Stereo-out? Are the Input Channel Mapping and Output Channel Mapping settings visible?

Thanks Gilongo. My Bass and Mic are connected via the Behringer UM2 audio to usb interface and you'll see from the screen shot that the UM2 is selected as the default input.
The next screen shot shows the same selected in Jamulus, i.e. system default.
Ah ok - I should have checked what a Behringer UM2 was. I thought it was a mic.
In that case you can go back to Stereo in the Audio Channels setting. But I'm not sure I've seen your problem described before. Other people seem to be using the UM2 OK.
It's intriguing that you can hear other people and that Garageband is working (I assume you are not running Garageband at the same time as you are running Jamulus).
Could there be some weird problem with your OS or the version of Jamulus you have? What versions are you running?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The version of Jumulus is 3.5.6 and Mac OS 10.15.5.
I wouldn't normally think of using GarageBand with Jamulus but in my desperation to make it work I have installed Blackhole with the idea that as I can put a signal into GarageBand I can output GB to BlackHole and then tell Jamulus that is the input scource is blackhole (one of my band mates does this to input his midi piano and for him it works). But doesnt work for me. I think we've spent about two hours using facetime on our phones to make sure the correct settings are used
The above just lets you know what I have tried.

Something is muting your signal into Jamulus and it feels like some fundamental or obvious problem but I can't think what. Usually common problems surface on the boards, but this one seems unique.
I assume you've done all the obvious things: shut down (not just rebooted) the Mac and waited for 30 seconds in case it's some hardware reset that's needed? Same for the audio interface. Tried a different USB port, etc.
Then try building up the chain to isolate things. For example, if you have some way of connecting your mic or bass directly to the computer and seeing if that works with the audio interface disconnected, then do the same but with the audio interface but with one input, then two, etc.

I'll try the close down thing again and try a different USB port, but there's no way to connect either the mic or bass into the iMac except via a DAC into a USB port (and we know that works because I can record in GarageBand).
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
System Prefs > Sound should be set to Built-in Mic and Internal Speakers no need to change them, but set speaker volume to zero.
Jamulus should be set to in:Behringer/out:Behringer.
Connect your headset/earbuds to the Behringer headphone jack to hear sound from the Jamulus Server
It's odd to me that you're seeing USB Audio Codec instead of the Behringer model number. Ensure that you've installed any Behringer driver - that really shouldn't be needed on Mac, but check the Behringer docs and wrbsite to be sure
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
My point about the Mac not needing a driver is that, when a driver isn't needed, you should be seeing the Behringer in the Jamulus in/out list, where you can select it. Because you're not seeing it in the list, it appears to me that Jamulus can't see it at all. Here's a test...
Open Finder > Applications > Utilities and run Audio MIDI Setup
From the Window menu, choose Show Audio Devices (if it's not already shown)
Click on the + in the lower left corner and choose Create Aggregate Device
In the list of Audio Devices on the right, do you see your Behringer listed? Not "USB Audio Codec", but a different listing for the UM2 specifically?
If you don't see it listed, then the Mac probably can't see the device at all. The attached screenshot is of an Aggregate Device on my system, where you can see my iConnect AUDIO4+ audio interface in the list of Audio Devices (ignore that it's greyed out, that's because I took the screenshot while the iCA4+ was disconnected).
Ok, now I'm understanding. A member of my band is using the Behringer UCG102, a very simple guitar interface, and also sees "USB Audio Codec" on his Mac instead of a named identifier. But he's not having problems with Jamulus, so something must be different in your configuration.
Looking at your screenshots for Audio MIDI Setup, I see USB Audio Codec listed twice. UAC1 has OUT only, while UAC2 has IN only. Your screenshot of Jamulus' Device List implies that both are seen, since "in:UAC/out:UAC" is in the list. But maybe try these things:
In Audio MIDI Setup, select UAC1 and check the Master level on the right - ensure that it's at 100%
In Audio MIDI Setup, select UAC2 and check the Master level on the right - ensure that it's at 100%
In Audio MIDI Setup, make an Aggregate Device that includes both UAC1 and UAC2 (like your screenshot). On the right, enable Drift Correction for both devices and set Clock Source to be UAC1.
In Jamulus, set Device to "in:Aggregate Device/out:Aggregate Device"
That should work. But we'll see. :)

I think that I have tried every combination my set up will allow. I can make all the combinations work with Garageband. I have powered down and left it for 5 mins , I have rebooted, if I had any I'd have torn my hair out.
I'm going to try re-downloading and re-installing Jamulus.

If you can't get it working, perhaps you can screenshare with another Mac user and they can help you troubleshoot? I could probably do it, but you're in UK and I'm in Seattle, so ~8 hours difference.

Apologies for the question: did you chose the right input device in Settings?
Thank you for replying, and Vincenzo, no need for apologies :-).

Just to fill in some detail here are, what I hope, are relevant screen shots. You can see that a signal is present at the sound card but I can't get any green from Jamulus and friends say that they can't hear either the mic or bass.

Good morning Gilongo,
The version of Jumulus is 3.5.6 and Mac OS 10.15.5.
I wouldn't normally think of using GarageBand with Jamulus but in my desperation to make it work I have installed Blackhole with the idea that as I can put a signal into GarageBand I can output GB to BlackHole and then tell Jamulus that is the input scource is blackhole (one of my band mates does this to input his midi piano and for him it works). But doesnt work for me. I think we've spent about two hours using facetime on our phones to make sure the correct settings are used

I'll try the close down thing again and try a different USB port, but there's no way to connect either the mic or bass into the iMac except via a DAC into a USB port (and we know that works because I can record in GarageBand).
A few suggestions:
Thanks Chris. I'll try your suggestion, speaker set to zero etc.
'USB Audio Codec' because Behringer dont have an in-house driver (not needed for Mac, as you say) for the UM2 - their cheapest - I know, I'm tight!.
Check out the UM2 on their website there they recommend a standard driver for windows users and nothing for Mac OS.
Ok tried all of the above. Still nothing. I can hear others but never see any green showing my sound.
This is super weird. If you have access to another machine, are you able to test it with that?
Unfortuneatley no. I have an iPad pro but I dont have a suitable powered interface as the UM2 requires power from USB.
My point about the Mac not needing a driver is that, when a driver isn't needed, you should be seeing the Behringer in the Jamulus in/out list, where you can select it. Because you're not seeing it in the list, it appears to me that Jamulus can't see it at all. Here's a test...

Hi Chris. Thanks for help. I've attached a screen shot of the Sound Card and Audio midi setup. Also one with Aggregate device.
The Mac doesnt see it as UM2 as you suggest but clearly it knows it's there because :
a) it isn't there when disconnected and
b) I use fine for GarageBand.
Thanks again.

This shows aggregate device used and input working at sound card and the selection in Jamulus.
Thanks Chris
