@zatarra Thank you very much for this Howto.
It took me some time to get it working by combining your code with the code from axel. I see you’ve update your intructions to include Fornoth now as well.
After then I could see OSMC in Spotify, but I heard no sound. With your latest update with assigning the hardware it now works!!
I see people like @yotic having trouble with obtaining their appkey.
Indeed the website now shows a link to a google docs form (Direct link)
I’ve filled in the form and only after 3 weeks I got my key, so this can take some time. Mind you, you’ve to fill in your exact username and e-mail associated with your account, so authentication with e.g. facebook doesn’t work.
After I’d received my appkey, the attached appkey didn’t work as well. I had to convert the BASE64 APPKEY in the body of the mail to a binary file. I’ve read this is sometimes the case. You can convert it e.g. here: Base64 Online - base64 decode and encode
