Spotify Connect Web


  • Hi awiouy,


    why is it not possible for the addon to send sound to HDMI and headphone, like kodi can do it? Is it to difficult to code?
    For my case it is enough to get the sound over headphone, so i am only interested in the reason.

    Hello Cruiser!


    I am glad to see you on this thread ;)


    On Raspberry Pi, Kodi and spotify-connect-web use distinct sound architectures (pulse audio for Kodi, alsa for spotify-connect-web).
    I am not aware that alsa is able to playback via hdmi and jack (this documentation suggests that hdmi and jack are exclusive).
    If you find out a way, please let me know, and I will gladly implement it


    Cheers

  • Hi awiouy,


    sure, the world is small
    With the documentation, i understand. And i can't read it different, there is no solution for that.
    So, i am glad, that one output is enough for me

  • Hello.


    My Spotify-App on the mobile dont see the rpi3-libreelec-device.


    I have started the service:

    Do i make some things wrong ?


    Sorry for the circumstances

  • The service also has a web server, on port 4000 of your LibreELEC device. You can get useful info from there (eg are userid/password correct)

  • Here is a preview release of the addon with passwordless/multiuser login


    It works fine here.


    Please let me know if it works for you, too

    Thanks for your work. I was looking for something like this for a while.


    I tried your addon on RPi3 and playback works fine but sadly the sound was very damped and did not sound very nice at all. I used the highest bitrate.

    Hello Gerrit!


    Thank you for the feedback.


    What sound interface are you using? Onboard via jack?


    Onboard audio sounds clunky, indeed, and you may have a better experience with an external sound card.


    It would be nice to have reports about sound quality with external sound cards.

  • Hey Awiouy,


    Great plugin man! Exactly what I had in mind when I started the thread in "feature requests" and it saves me an extra RPI for audio.
    Would it also be possible to view the details of the currently played song in Kodi besides the webserver?

    Hello!


    I would not have been aware of spotify-connect-web without your feature request.
    Thank you for pointing it out.


    As for displaying details of the currently played song in Kodi, it is certainly possible.
    My skills in Kodi/Python are however quite limited, and I will therefore leave it to someone else.


    Moreover:
    - you can already get these details from your Spotify app and from the web user interface
    - spotify-connect-web can play music (via a sound system) when the display (the tv) is turned off
    - spotify-connect-web is still alpha, and therefore is likely to change/die


    It is therefore doubtful that this feature is worth the effort

  • Well i could think of one thing. When i have a party at my Home it would be nice to show the playlist/current song on the TV screen, so if others add music to the playlist they and all other non-djees can follow it on the screen...;-)


    One other techical thing.
    I have compared the alsa sound quality with the volumio/spotify connect sound....it looks like the volumio version has better soundquality. More brighter in the frequenties or better dynamic range...don't know how to explain this exactly. Both are set to 320.

    Thank you for this interesting lead.
    Do you know where I can find the source of volumio, especially how it calls spotify-connect-web?

    I think it is the same Fornoth spotify-connect-web as you use but then on a volumio 1.55 build, but didn't try it yet on the new volumio 2 build. Here is a volumio forum link where i got the info Spotify Connect : Development talks - Volumio


    But for the installation i just followed the Fornoth github page and used the pre-built chroot installation

    Hello!


    Thank you for your reply.


    The addon is based on the spotify-connect-web packaged release (~15 MB), not the pre-built chroot (~ 180 MB).


    I have tried to install the pre-built chroot to find out if it makes a difference with respect to sound quality.
    The pre-built chroot however failed to install (installation complains about invalid tar magic).


    If you or anyone here:
    1. manages to install and run the pre-built chroot on LibreELEC, and
    2. confirms that sound quality of RPi onboard audio is better with pre-built chroot than with the current addon
    I will gladly consider updating the addon.


    In the meantime, I can only confirm that sound quality is better with an external sound card than with RPi onboard audio via headphone jack.


    Cheers
