after upgrading Safari to version 10.0.2 a couple of days ago, I am no longer able to stream Soundcloud via Airplay (I choose the output device with Alt-Click on the sound icon in the menu bar).
All I get is constant clicking/buffering noise, as if it were connecting and then immediately dropping. With some songs it managed to play one second of music, which then got stuck on repeat like a jammed CD.
Youtube seems to work fine with Airplay on Safari, and Soundcloud streams without problems from Firefox.
Anybody else have this issue? Any ideas on how to solve this? I've tried emptying the Safari cache, but it didn't help.
