The present aspects relate to audio management for a web browser. For example, an electronic device such as a mobile device may enable a user to navigate to a webpage within a web browser. In some embodiments, the webpage may automatically initiate presentation of audio content. However, the user may wish to quickly silence the audio content that is playing without locating the media player controls of the audio content within the webpage. Accordingly, the present aspects provide audio control for a web browser. Specifically, an audio control affordance may be displayed at a noticeable and recognizable position or area in the web browser, and based on a determination that a webpage includes audio content and/or determination of playback of the audio content. The user may in turn readily adjust a property of the audio content.
