Provide an understandable volume and mute interaction

What to change

Ask the supplier to make volume changes and mute state clear through visual, keyboard and assistive interaction.

A worked example

Illustrative example

A visitor mutes a clip to read the page, then unmutes and returns to the previous chosen level with an accurate control label.

How to check the result

Accept when users can adjust, silence and restore audio deliberately and the controls accurately represent the resulting sound state.

A mistake to avoid

Changing the icon to a crossed speaker without updating its accessible name can leave the announced action opposite to the actual state.

Your action checklist

Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.

Decisions to recordPlay a test clip at a suitable level and use the volume control with the keyboard. Check the current value is understandable and changes predictably.Mute and unmute through the separate control if provided. Ask the supplier to demonstrate whether the prior level is restored and how the state is announced.Try the slider on a phone and at enlarged zoom. Its target should remain usable without requiring a precise drag as the only input route.
