A new update has rolled out to allow you to toggle the noise.
When Valve updated the Steam client recently and changed the appearance of the platform, it actually surprised a lot of users, as it had become a bit of a trend to see updates being released but them having little to no perceivable impact. While this recent update has brought a lot of welcome improvements to Steam, the little sound that it now makes whenever a game or update finishes downloading, or when you get an achievement, has led many users (myself included) into wondering how to disable such a feature.
