Abstract
Apparatus and methods digital audio bus reliability are disclosed. In certain embodiments, a digital audio system includes a plurality of audio devices connected by a first digital audio chain in a clockwise direction and a second digital audio chain in a counterclockwise direction. The first digital audio chain and the second digital audio chain run concurrently, and a controller selects which audio chain to operate at a given time for audio connectivity. For example, the controller can initially select the first digital audio chain to provide audio connectivity, but transition selection from the first digital audio chain to the second digital audio chain in response to detecting a node failure in the first digital audio chain. Thus, the system is tolerant to node failures while maintaining system connectivity.
