Should definitely ship with support for FLAC
Keavon Chambers commented
This is now supported by both Firefox since v51 and Chrome since v56. Please make this a universal format by supporting it in Edge as well.
Jeremy Karlsson commented
"Starting with Firefox 51, FLAC support is built natively in Firefox."
Confirmed in latest Nightly.
Google, even though having the feature completely done and integrated in Chrome OS and Google Cast, still doesn't ship it in the Chrome browser.
