The first Beta install stopped recognizing a Yamaha USB audio interface. The next two installs brought the recognition back. The last Beta install doesn't recognize the interface completely. The midi implementation works but the audio implementation isn't recognized in Audio/Midi setup. This might be something to look at in the next Beta release or something audio interface venders should look at in their next driver release.
USB audio/midi interface with OS 26 Tahoe
Thanks for bringing this to our attention. Can you provide exact details of the model of this USB device? If possible, please file a Feedback with a sysdiagnose and respond with the feedback number.
It's a Yamaha 01V96i digital mixing console with a USB computer connection for 16 audio inputs and 16 outputs. It's not recognized in the audio window of Audio/Midi Setup but is recognized in the Midi window. The midi implementation seems to work fine in terms of controlling faders on the mixing console from the computer and the from the moving faders on the console corresponding to computer screen.
Additionally, it was working with a beta version of a Yamaha Steinberg USB Control Panel (4.0.3b). When it stopped working, I reverted back to the official release of the Yamaha Steinberg USB Control Panel. (3.1.4) I've deleted and installed both versions and neither seems to work now.
