I am trialling Audirvana and I am enjoying the much improved sound. However, I was using the Creative E-MU 0404 USB as a DAC which worked OK until I noticed that Direct Mode could not be enabled. It turns out (according to the FAQ) MacOS Sierra kernel extension IOAudioFamily.kext is ‘broken’ in that respect. So I followed the instructions and installed IOAudioFamily.kext from the El Capitan Installer. The Installation went OK and audio that doesn’t go though Audirvana is fine. However when I try to play anything through Audinirvana it plays at half-speed. This happens whether Direct Mode is enabled or not. Can you help? I am using the Built-in Line Out for now but sound is a bit coarser.
