Opera 44 no longer plays audio streams
Ubuntu 16.04.2 LTS (x86_64; Unity)
Last week, Opera was playing streams from http://tunein.com (example link: http://tunein.com/radio/Morning-Edition-p3/)
This week, all links I have saved, as well as others I try from source pages fail to play (example: http://playerservices.streamtheworld.com/api/livestream-redirect/WAMCFM.mp3) [fails to download].
All links work perfectly on Chrome, Chromium and Firefox on same computer. Only Opera fails.
VIDEO streams seem to work just fine (example: http://wamc.org/wamc-live-studio-cam) [Note: if the studio cam isn't on there, you get the audio anyway ... which is oddly interesting ... and what I am using now to listen through Opera]
I have cleared cache and history, tried changing setting of flag "User interaction required for media playback" - mostly because of the commentary on that flag: "User interaction required for playing media elements. Disabling this will allow autoplay to work." - however disabled or enabled, no change.
I have changed both VPN on/off and even unblocked ads, etc - no change.
I'm relatively new to Opera. Am I missing something obvious?
