A method includes receiving, at a server from a first content source, a media content stream. The media content stream includes native video content and native audio content. The method includes receiving, at the server from a second content source distinct from the first content source, an audio content stream associated with media content of the media content stream. The method includes generating, at the server, a composite stream that includes first packets and second packets. The first packets include first data corresponding to the native video content, and the second packets include second data corresponding to audio content from the audio content stream. The composite stream does not include the native audio content. The method also includes initiating, from the server, a transmission of the composite stream to a media device responsive to a request for the media content with the audio content.
