Snapserver

1st Official Post

    Hello

    I've just installed the SnapServer addon onto my rpi3

    it seems to be working well except my pulse.log has an error message every 10 secs and I dont know what is causing it

    error message is [pulseaudio] sap.c: sendmsg() failed: Connection refused


    snapserver & snapclient both report that they are version 9.0.102

    librespot reports as version 9.0.113

    kodi is 18.0-RC5 Gitc9d65b1

    if anybody has any ideas what is causing the message

    [pulseaudio] sap.c: sendmsg() failed: Connection refused

    to be repeated every 10 secs i'd be glad to know

    This is just a warning. From what I see it comes because rtp module is loaded. You can see this by

    Code
    LibreELEC:~ # pactl list short modules |grep rtp
18      module-rtp-send source=librespot_sink.monitor destination_ip=127.0.0.1 port=6666 source_ip=127.0.0.1

    And seems it is used/loaded by librespot: LibreELEC.tv/librespot-03_pulseaudio_sink.patch at master · LibreELEC/LibreELEC.tv · GitHub

    You can unload it by

    Code
    pactl unload-module module-rtp-send

    but maybe functionality will stop working.

    Thanks for updates, I look forward to hearing further about issue.

    Obviously I can just stop the logging and the issue will be unnoticed, but I don't like knowing there issues lurking away in the background.

    I had a look.

    I coded snapserver.start to create a PulseAudio sink for Kodi, but I did not suspend it when unused.

    This should not cause problems other than the messages you see.

    I will fix this in an upcoming revision.

    I intend to use json RPC to configure Snapserver (set stream, set clients) and Snapclients (set volume), which should take a couple of weeks.
