Tried the spotify web connect with varied success.
In the meantime I ran across Spotifyd, its supposed to use the API from Spotify and works/connects like the original.
No special configurations required like spotify web connect etc. just unzip the file, move it to /usr/bin and create a service and update the conf file.
Seems pretty solid with 4 different Dacs XMOS, Amanero, and with Allo digi one sig. Volume etc works but seems to be picky with Amanero.
And best of all the SQ is exceptional, Raspotify, liberspot etc all seemed a tad dull...just enough to where I knew it was not directly from Spotify but through something. Spotifyd sounds clean and airy not dull at all.
