[SOLVED] Spotify connect stopped playing audio

[new_bloke]

I can confirm that compiling the librespot executable from the dev branch of the code (at commit 2ea7436) resolves the issue for me. I also discovered that older versions of the Spotify client (for me on Mac) seemed to cause a different authentication error. This probably explains why the Spotify community support folks are asking if the affected TVs are due a firmware update...
