Comment 20 for bug 1504065

Michael: I don't know about specific media players, but mobile operating systems do something similar to what we do:

Android has such a popup dialog: https://lh3.googleusercontent.com/-w7eI7XSyGeA/ULSub0P_5HI/AAAAAAAAYBA/WBSCTnj1vwQ/s518/2012+-+1

Windows 10 as well: http://superuser.com/questions/991638/how-to-disable-high-volume-warning-dialog

IOS seems by default to not allow going over the value required by the law, but there's a toggle to disable it in the settings: http://www.head-fi.org/t/635993/lightbox/post/8863328/id/719624
