1.4.2 Audio Control

WCAG reference for comparison

1.4.2 Audio Control: If any audio in software plays automatically for more than 3 seconds, either a mechanism is available to pause or stop the audio, or a mechanism is available to control audio volume independently from the overall system volume level. (Level A)

Since any content that does not meet this success criterion can interfere with a user's ability to use the software application, all content in the software (whether or not it is used to meet other success criteria) must meet this success criterion. See WCAG 2.0 Conformance Requirement 5: Non-Interference.

WCAG2ICT additional guidance

This applies directly as written, and as described in INTENT from Understanding WCAG 2.0 (above) replacing “on a Web page” with “in a non-web document or software ”, "whole page" with "whole document or software", "on the Web page" with "in the document or software" and “any content” with “any part of a non-web document or software”.

With these substitutions, it would read:

1.4.2 Audio Control: If any audio in a non-web document or software plays automatically for more than 3 seconds, either a mechanism is available to pause or stop the audio, or a mechanism is available to control audio volume independently from the overall system volume level. (Level A)

Note: Since any part of a non-web document or software that does not meet this success criterion can interfere with a user's ability to use the whole document or software, all content in the document or software (whether or not it is used to meet other success criteria) must meet this success criterion. See Conformance Requirement 5: Non-Interference.
