Technologies for framework-level audio device virtualization

A method for multiple audio instances, the method comprising:

• executing, by a computing device, a plurality of application framework instances;
• monitoring, by the computing device, for an application framework instance switch in response to executing the plurality of application framework instances;
• determining, by the computing device, whether a current application framework instance of the plurality of application framework instances is a foreground instance in response to an application framework instance switch;
• selecting, by the computing device, a physical audio output device in response to determining that the current application framework instance is the foreground instance;
• and
• selecting, by the computing device, a null audio output device in response to determining that the current application framework instance is not the foreground instance.

One or more computer-readable storage media comprising a plurality of instructions that in response to being executed cause a computing device to:

• execute a plurality of application framework instances;
• monitor for an application framework instance switch in response to executing the plurality of application framework instances;
• determine whether a current application framework instance of the plurality of application framework instances is a foreground instance in response to an application framework instance switch;
• select a physical audio output device in response to determining that the current application framework instance is the foreground instance;
• and
• select a null audio output device in response to determining that the current application framework instance is not the foreground instance.
