![]() ![]() In Audirvana Plus 2.5.4, it is disabled by default." Until they fix it, or I find a user friendly workaround, you have to disable Direct Mode (option in Audio System page of preferences) to get playback to start. Had they used components of Core Audio (as most all players do), they wouldn't have this problem.įrom the Audirvana folks: "Apple has just released macOS 10.12 Sierra that has a regression that breaks Direct Mode. It doesn't adhere to Core Audio APIs, and Apple has no responsibility in fixing Audirvana's problematic programming method in support of "Direct Mode".Īudirvana chose to create some of their own "building blocks" (bypassing Core Audio) and now those home grown building blocks no longer function correctly in macOS Sierra or High Sierra. So called "Direct Mode" by it's very claim resides outside of Core Audio. A programmer then puts the blocks together.Īpple did not break Audirvana "Direct Mode" in macOS Sierra or High Sierra. A good API makes it easier to develop a program by providing all the building blocks. This is all thoroughly documented and tested as a whole. The Core Audio API specifies how software components should interact. Core Audio provides a set of layered services that reside on top of a Hardware Abstraction Layer (HAL). Programmers are to stay within this framework of Core Audio through the Core Audio Software Development Kit (SDK) and it's Application Programming Interfaces (API). It presents it's own set of problems as Audirvana users have experienced.Ĭore Audio is Apple's software framework (architecture) designed to handle the low level programming needs for the software developer's application. No other player that I am aware of has this "Direct Mode", and for good reason. But Audirvana's "Direct Mode" is unnecessary and of questionable value. Software developers please feel free to elaborate or make corrections.Īudirvana "Direct Mode" claims to fully bypass Apple's Core Audio, supposedly for improved sound quality. Here's my high level take on Audirvana "Direct Mode" as a non-programmer.
