[HOW-TO] Spotify Connect Web for Moode

[doodydoo]

Hi,

I originally used the Spotify Connect solution builtin to moOde but wanted some gapless goddness so I thought I'd give this a go. I've managed to get everything built and installed, and when I start up the spotify-connect-web service I see the following messages:

Loading Spotify library...

Which looks good to me. Until I select 'devices available' on Spotify on my phone when i get the following messages:

I get this block of messages everytime I select the 'devices available' option. I am on a fresh install of the current moOde (6.4.2) and the avahi service is started and a sudo systemctl status avahi-spotify-connect-multiuser.service gives me:

I have read through the thread and can't find anything like this. I did try changing from gevent.wsgi import WSGIServer to from gevent.pywsgi import WSGIServer just in case but without luck.

Any help would be really appreciated, mixed DJ albums really don't sound the same when they're not gapless ;-)

Well I've managed to surprise myself and fix this on my own so I'll document what I did just in case anyone else has the same problem.

After working through the error messages and doing a few searches I arrived here: https://stackoverflow.com/questions/6013...-to-heroku which mentions an upgrade to the werkzurg python package which causes problems with versions of the flask package below 0.12.4. The suggestions for fixing this issue included upgrading to flask v1.0.0 and higher or downgrading werkzeug to below 1.0.

Rafa's requirements.txt includes the line Flask==0.11.1 so upgrading to V1 probably isn't a good idea so I added wekzeug<1.0, re-ran pip install -r requirements.txt, rebooted (not strictly necessarily but whatever), started both the services and now it works just fine, gapless goodness achieved!!

I'll open an issue on github so Rafa can take a look at it and verify what I've done but right now it works just fine.

Just to be complete I installed this on a fresh copy of moOde 6.4.2 on a Raspberry Pi 3B+ with an IQAudio Pi-Dac+. The only change I made to the procedure on github was to change the hw:1 to hw:0 on the slave -> pcm entry in /etc/asound.conf, mine looks like this now:

pcm.softvol {
  type softvol
  slave {
    pcm "hw:0"
  }
  control {
    name "Master"
    card 0
  }
}

Thanks to Rafa for all your work, it's so good to get gapless playback, it makes such a difference and thanks to Tim, I am so happy with moOde, it gives me everything I need and a whole lot more. Just need to get gapless playback for Spotify baked in ;-)
