USB Audio Codec not available in macOS 15.4.1

I upgraded to Sequoia 15.4.1 yesterday, and no the USB Audio Codec option for Input in Audacity is no longer available. I've restarted my Mac, uninstalled and re-installed Audacity, triple checked all my settings and I can't get the option to appear.

I collect a lot of vinyl and have been digitizing them for years with the exact same set up.... hooked up exactly the same way. The only thing that has changed is my OS version.

Any help or suggestions ?

Similar Issue,

After Upgrading to 15.4.1 the USB PnP Audio Driver option for my Sound Output is no longer available. I am using a Hyrta USB Hub. Been using it since MacOs 13. All updates prior to 15.4.1 did not have this issue. Restarted several times, disconnected USB Hub Several times. Disconnected all items from the Hub several times. Still nothing.

The Video ports in the Hub are working fine, just no Audio and unfortunately the hub connector covers the headphone jack on the macbook. So I can't connect directly in and have the monitors connected at the same time :(

I upgraded to 15.5 and it seems to have solved the issue for me. I now see USB PnP Audio Driver option in my Sound Output list. So far it has been there consistently.
