Microsoft has rolled out an update for the Audio settings part of Windows 10 Mobile. This latest release improves the user interface of the settings area, enabling you to manage your sound output and equalizer options in a more unified experience. This seems to be the only major change here, and we're unable to locate any features we deem as new.
The update applies to newer phones too e.g. Lumia 950, however we have been unable to identify changes to a bug on our phone.
