Audio On macOS

Overview

Roon supports two output mechanisms on Mac OS X: CoreAudio and *ASIO*.

CoreAudio is Apple's native audio framework.
ASIO support on Mac is extremely limited--currently the only devices we are aware of are manufactured by exaSound. If you don't have one of these, you will be using CoreAudio.

Both are capable of bit-perfect playback. CoreAudio is a more modern system, with stronger support for convenience features like volume controls and device identification, and ASIO is more bare-bones and minimal.

For an in-depth overview of the Audio Configuration in Roon, check out our [[Audio Setup Basics]] page.

This page is for mac-specific notes and issues.

Recommended Setup for exaSound devices with ASIO drivers

Make sure that the exaSound dashboard is set to "ASIO" mode. If it leaves ASIO mode, or if the dashboard exits, Roon will have difficulty accessing the device. If you have having problems unexpectedly, this is the first thing to check:

Then, in Roon's audio settings, enable the (2ch) version of the driver, even if you have an 8-channel device

Finally, make your setup screens look like this:

Then play some music.
