Synchronization of audio across multiple devices

A method for synchronizing audio data among a plurality of display devices in communication with a computer device, comprising:

• determine, at an operating system executing on the computer device, a plurality of audio data subsets with audio data from an audio stream to transmit to a plurality of display devices in communication with the computer device via a universal serial bus (USB) connection;
• obtaining a current frame number of a display device render buffer from a first display device of the plurality of display devices;
• determining an updated frame number by adding a constant to the current frame number;
• generating a plurality of USB request blocks, where each USB request block of the plurality of USB request blocks includes the updated frame number and a packet with one audio data subset of the plurality of audio data subsets;
• and
• sending each USB request block of the plurality of USB request blocks to a corresponding display device of the plurality of display devices.

A non-transitory computer-readable medium storing instructions executable by a computer device, comprising:

• at least one instruction for causing the computer device to determine a plurality of audio data subsets with audio data from an audio stream to transmit to a plurality of display devices in communication with the computer device via a universal serial bus (USB) connection;
• at least one instruction for causing the computer device to obtain a current frame number of a display device render buffer from a first display device of the plurality of display devices;
• at least one instruction for causing the computer device to determine an updated frame number by adding a constant to the current frame number;
• at least one instruction for causing the computer device to generate a plurality of USB request blocks, where each USB request block of the plurality of USB request blocks includes the updated frame number and a packet with one audio data subset of the plurality of audio data subsets with one audio data subset of the plurality of audio data subsets;
• and
• at least one instruction for causing the computer device to send each USB request block of the plurality of USB request blocks to a corresponding display device of the plurality of display devices.
