A content server system is provided that includes at least one processor configured to store a user account for a user at a content server of the content server system that is configured to serve server-side rendered content to a client computing device of the user. Audio is played out via a sound output device associated with the client computing device. The at least one processor is further configured to determine a licensing identifier associated with a device of the user or the user account of the user, send the licensing identifier to a third-party licensing server device, receive an indication that an active license is associated with the licensing identifier, determine that the user is authorized to access a digital rights managed audio rendering software, and cause audio of the server-side rendered content to be rendered using audio rendering algorithms of the digital rights managed audio rendering software.
