Not recognizing audio from turntable after Catalina Update

[dth0829]

Sorry about that. I will also try to amplify the sound once I get home.

Even with amplification, there is nothing

I am having the same issues with my audacity with Catalina mac. As far as checking the privacy settings and microphone its not even showing the audacity app and I am not sure why as I am following the directions, download the dmg, drag the icon to the app folder.

What make and model is your turntable?

I thought that might be the case.

Some new information has come through from the developers.
Apparently, in addition to dropping support for 32-bit application, Apple decided to only allow software that they say you can run.

Beginning in macOS 10.15, notarization is required by default for all software.

This means that software developers have to ask Apple's permission to allow their software to run on Catalina.

Apple have since relaxed this requirement - probably because it broke too much software, but the extent to which it has been "relaxed" is currently unknown, and may change with each macOS update.

Sadly, this decision by Apple goes against the spirit of open source software (https://www.gnu.org/philosophy/free-sw.en.html)

“Free software” means software that respects users' freedom and community. Roughly, it means that the users have the freedom to run, copy, distribute, study, change and improve the software. Thus, “free software” is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech,” not as in “free beer”.

The new restriction probably violates the terms of GPLv3 (the current version of the GPL open source license agreement), so I expect that many open source applications will no longer be available for Mac users.

In the case of Audacity, the software license is GPLv2. At this stage I am unsure if Apple's notarization requirement legally conflicts with GPLv2, though it is certainly against the spirit of GPL.

Given the above, I am surprised that Audacity runs at all on Catalina - perhaps that's due to the requirement being temporarily "relaxed". My guess at this stage is that although Catalina currently allows Audacity to run, it prevents it from accessing external resources, including audio capture (recording).

These problems are not unique to Audacity. Many other audio products are saying "don't update to Catalina yet", including:

Ableton
Acustica Audio
Akai Professional
Antares
Boss
Denon DJ
iZotope
Korg
Native Instruments
Numark
Pioneer DJ
Pro Tools
Roland
ROLI
Steinberg
and many more...

I note that many of these make USB hardware, so perhaps that's an indication of problems with USB audio devices (?).

For now, the Audacity website says that Catalina is not supported by Audacity. That information will be updated when we know more.

And many thanks to noraa for posting that workaround

I'm having exactly the same issue. Even when I set my recording input source to ""Built-In Microphone," Audacity is not hearing anything. Unfortunately, it's not on the list of apps allowed access to the microphone, and I can't find any way to add it manually.

That's a kick in the head, isn't it? I can think if a lot of corporate reasons they would want that.

I just upgraded to Catalina and bought a USB turntable, the audIo technical LP5. I’m having exactly the same issue. However, I also seem to not be able to have GarageBand hear the device either. Does anyone know if you have to connect the USB and the RCA cables? Fire and RCA to jack adapter? Or should just the USB cable suffice?
