Best Available Audio Output Paths

Best Available Audio Output Paths

Suppose there are specific audio paths that the administrator does not intend to use. In that case, configure the best audio path to ensure that specific paths are unavailable to the user. Selecting a specific audio path can reduce frustration for users that might have to override an incorrect choice over and over.
The user can change the audio path from the Desktop Audio Panel. However, the user's choice may be overridden upon a dock or undock event, depending upon the administrator's configuration.
Preventing an audio path from being chosen as optimal does not restrict the user from overriding that path. Instead, it prevents the system from selecting it automatically.
Each time the set of audio devices changes (including docking and undocking), the best path routing recalibrates and overrides any previous setting implemented by the user.
Android has a specific methodology for best path routing that is automatically applied if the administrator does not change the default configuration.
