    Synchronization problems, recently

    Hi forum,

    Using Logitech Media Server Version: 7.9.2 - 1572530107 @ Thu Oct 31 15:08:12 WEST 2019 (and I think v7.9.2, 1571644358, Mon Oct 21 10:08:21 WEDT 2019):

    I've notice a couple times in the past two weeks a significant (second or two) delay between a wired Boom and a wifi-connected SB2 that are in two adjacent rooms (hence my ability to notice -- not certain whether this applies to other SB devices in the house). These are set to be synchronized. The feed in both cases was a relatively low bitrate internet stream (CBC Radio 1).

    I see a few errors in the log, but nothing that looks at all related. (Mainly not being able to connect to mysqueezebox.com and "Failed to fetch http://bpaplugins.googlecode.com/svn...o-playhls.xml: 404 Not Found", which appears to have been there for months.)

    For years now, synchronization has worked basically flawlessly, with the only problem being that if the network communication with one of the devices gets too slow for some reason all devices will stop while the server gets things back in synch. I only noticed the problem after I updated to the Oct 21 1571644358 version. I haven't had problems with synchronized devices being out of synch in literally over a decade I think. Wondering whether something changed in the code recently that might be responsible or if anyone has suggestions on how to debug this.
    Server: LMS 7.9.0; Study: SB Touch > C 375BEE DAC; Spouse's Study: SB Boom; Master Bedroom: SB Boom; Living Room: SB2; Family Room: SB2; Kitchen: SB Boom; Spare: SB Boom

    The googlecode host for PlayHLS has been dead for 2 years !
    Please change to the a new version of the plugin which does not need ffmpeg http://bpa-code.github.io/bpaplugins...ls-v2-beta.xml

    Nothgin has really changed in the code specific to sync. However, lots of changes happen with https support so make sure you have an up to date OpenSSL as older version can cause https delays. Also check IO::Socket::SSL version in WebUI Settings/Information. Should be 2.??

    Sometimes which device is "master" can affect quality of sync.
    It sounds like a network issues to one of the players.
    You can adjust the sync parameters of each player to allow more "leeway" using WebUI Settings/Player/Synchronize - check the help and only adjust one at a time to see if it helps.

    Do you see the same problem when playing local tracks (as opposed to internet streams/services)?
