    Qobuz Dropouts

    I am running LMS 7.9 with the Qobuz plugin. All was well until a few weeks ago when I started having total dropouts when playing back Qobuz playlsists. They only last for a second or two and happen every couple of minutes (varying, not periodic). It does not happen if I am playing Qobuz playlists directly on my Mac, suggesting it is an issue related to Wifi coverage (playback is via UPnP and using Squeezepad as a controller).

    I can't think of anything in the house that could suddenly have started disrupting things and have tried turning several appliances etc. off to no avail.
    I did change the Mac OS to Catalina a few weeks back - would this have anything to do with it ?

    Qobuz version is
    JS version5.3.0-b009
    Desktop version5.3.0-b005

    Any ideas where can start to look for the source of the problem ?
    Thanks

    Could you explain your setup a little more? I'm confused which parts are
    being used... what kind of player are you using?

    Ok

    Mac running Catalina OS. Late 2017 model with 16gB RAM.
    LMS 7.9 with Qobuz, UPnP plug-ins installed.
    Downloaded FLAC library is on the Mac.
    Qobuz app also on Mac but just used for listening when I am with the Mac (upstairs from stereo system).


    IPad running Squeezepad controller. Gives access and control of both FLAC library and Qobuz streaming.
    UPnP output from Mac over WIFi router to Lyngdorf digital amplifier (UPnP equipped).

    Dropouts occur when streaming Qobuz and FLAC library. Sounds like a WiFi issue but why all of a sudden (may have followed change to Catalina but not sure of the exact dates). I have tried changing router channel but no joy. How can I tell whether the a Mac is connected to the router by Ethernet or wirelessly (it is cabled physically ) ?

    Qobuz mention they have a 64 bit version of their software - should I install this in preference to the version I have had for over a year (presumably 32 bit).

    Hi there,

    Speaking of Dropouts, I am not 100% sure I understand how LMS is managing Qobuz Hi-Res files and players.
    E.g a Transporter and a Boom, have set up the Qobuz plugin to stream FLAC hi-res 24bits/96kHz.
    Is that correct to say that the stream would play natively on the Transporter and would be converted on the fly by the server for the Boom?
    Right now, depending of stream properties, I see issues on my Boom or Radio for files above 2500Kbps (audio is suttered or there is buffering on some files).
    Any way to avoid this except going back to 44.1 kHz? I have updated my server to a pi4, but still have the issues.

    Thx for your feedback ;-)

    I'd say yes.

    Check the CPU when this happens. Is it really the bottleneck?

    CPU is a little bit more active, but nothing major.

    Listening to Velvet Moon from Billie Holiday on Qobuz using a Boom or Radio

    - if in 44.1 kHz, 696Kbps On Max2Play interface, CPU load = 0.25 --> all ok
    - if in 96 kHz, 3036Kbps - CPU load = 0.35 --> buffering and sutters
