Hey Steve,
Lastly please keep in mind that if I set the device to Internal Mic and Speaker it plays with out turning gray.

So to me Mojave is granting access to Audacity.
Screen Shot 2018-11-02 at 11.47.42 AM.png

In Audacity “Preferences > Quality”, set the default sample format to “32-bit float”.


In “Group 2 sound settings”
“Audio Devices > UMC404HD 192k > Output” set Source: Default / Format: to “2 ch 16-bit 44.1 kHz” (if available).
Please say which options are available here as there may be a better combination, but Audacity only supports 2 channel playback.


Audacity → “Audio Device Info” has a “Save” button at the bottom. Please save the info and attach the saved text file to your reply.


Could you also post the “Input” part of this:

Good Morning Steve

Thanks for the requests.

  1. In Preferences I set the Quality to 32-bit float. Picture attached. Note that there is a also Settings for Real-Time Conversion and High Quality Conversion

  2. In Audio Devices>UMC404HD>Output
    2-Ch was not available. Every option is 4 channel.
    Format relates only to speed select options 44,100 48,000, 88,200 96,000 176,400 192,000 Hz.
    Input bit depth is fixed at 24-bit Integer regardless of what output is set too. Picture attached
    It is set to 44,000 Hz and other is fixed on 4-ch 24-bit integer

  3. In Audio Devices>UMC404HD>Input
    Always 4 channel
    Format options are integer 16 or 24 bits
    Which can be selected with the rates shown in #2
    I set output to 4ch 16-bit integer 44.1kHz

Audio device info attached

I made the 32 bit float change and changed input to 16 bit and tested there was not change Bummer.

According to this (from deviceinfo.txt), Audacity and the UMC404HD are configured correctly and working.

What are you using as a sound input for the UMC404HD?

Is the UMC404HD showing an input signal is present? (the green LED associated with the input level should flash on when there is sound, and off when there is silence).

What happens if you now try to record?

Hi Thanks Steve for the quick response.
As I said previously, In sound on my Mac system preferences I see The USB Device In both Input and Output and they are selected and I also see signal on input volume, As you can see by the attachment.
Also as I pointed out Logic Pro X is able to access the USB Interfaces fine in both input and output. And the LED does blink with the microphone input.
So you can see why from my limited vantage point and expertise that I think it is a software bug of some sort.
I was hoping it was related to 64bit and 32bit processing associated with Mojave.

but if you click on the recording meter in Audacity, no signal shows in the Audacity meter?

OMG
Now it is working. I do see the VU meter and am now able to record.
Perhaps during the last power cycle it gave up giving me grief and decided to work.
Honestly, it was not working all along.
It just started working now.
Sorry

I believe you, and I’m very pleased to hear that it is now working.
I’ll leave this topic open, so if you happen to discover what fixed it, please let us know.

Thanks for all your hard and timely efforts
Now I plan to set Logic Pro X aside go back to audacity.
It has become a good friend.
I know this must sound nuts to some folks.
Stay safe

Hey,

I’m having a similar issue. Did you happen to find out what fixed it for you?

Cheers

I have a Blue USB Audio 2.0 microphone that I use to record on Audacity and I recently upgraded to Mojave 10.14.2. I tried the solution referred to in the locked forum - I gave Audacity access to my microphone - and it still will not record. I have everything backed up so I am thinking of going back to OS 10.13 but this new OS has some features that kind of like so I would rather not do that.

Does anyone have any other suggestions? I do a pre-recorded online radio show once or twice a month so if this can’t be fixed it is a show-stopper.

Thank you.

Have you given Audacity permission to access the microphone? (See: https://forum.audacityteam.org/t/no-signal-from-usb-turntable-mojave-solved/50763/6)

As it turns out the problem was with my microphone. It doesn’t work on anything. I’ve got a new one on order so hopefully that will alleviate the problem.

Had to take my MacBookPro to the Apple Store and have it downgraded from Mojave to Sierra in order for Audacity to work on my computer. Accidentally updated to Mojave today. Seems as if Audacity is still working. Has Audacity updated so that it is now compatible with Mojave?
If not, I have a huge problem on my hands as a voice actor.

Well I’ve been running Audacity released and alpha test versions (and old versions for QA testing) on my MacbookPro with various versions of macOS 10.14.x Mojave - with no problems.

Audacity 2.3.2 is a 64-bit app now and the Mac should stop complaining at you.

That’s not to say you can’t have other problems.

I have a huge problem on my hands as a voice actor.

Maybe a different problem than you think. What provision do you have if the Mac goes into the mud and doesn’t come back?
