I've been trying to find a solution to my problem, in vain.
I own a Harman Kardon Aura speaker which, according to www.spotifygear.com, is a supported device for Spotify Connect purposes.
And indeed, when it comes to sending music from portable devices (iPhone, iPad or any other Android device), everything works quite flawlessly.
However, sending music from Spotify's desktop application appears to be a complete headache, and apparently impossible. I'm running Windows7, with "HK Aura BT" added as bluetooth device. The PC and the speaker are definitely seeing each other. It is just not reflected in Spotify.
Thank you in advance for any input on this subject.
Solved! Go to Solution.
Now HK added the support for spotify connect to Aura with a new firmware (Released January 2016) https://www.harmankardon.com/software.html
Bad news are that i already updated firmware and still nothing is working with iphone app or desktop.
