arabesc Posted August 12 Share Posted August 12 I have a m/b with a built-in USB audio and an external USB DAC dongle. They worked flawlessly on previous macOS versions with AppleALCU.kext, but stopped working after upgrading to Sonoma. Both devices are visible in IORegistryExplorer, they have AppleUSBAudioDevice connected, but there are no AppleUSBAudioEngine. Any ideas on how to fix the issue and get the sound back?
