Re: [slim] Player synchronisation problems with new mesh wifi
That makes sense. So Shairtunes wasn't the culprit but the victim, and I drew the wrong conclusion from the error messages. Whatever's causing this occasional 37s dropout when players are synced and playing is quite a rare phenomenon in my case. I've had my RPi powered down and back up numerous times today, and haven't had one instance of the dropout problem. But there do seem to be one or two other users with the same issue, dating back to 2014. It seems like the RPi might be a common factor. chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=110765 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
Re: [slim] Player synchronisation problems with new mesh wifi
What I have observed on my own network is that, from time to time, my wifi system goes "nuts" which causes players to disconnect randomly. As a result, players in sync will stop and restart as soon as a player re-joins, this is the way LMS works. Then, you'll have all these messages from Shairtunes because each instance stops when the player is disconnected and restarts when it comes back. That can be very annoying and I've never been able to figure out why. I had that with 3 different generations of routers and PLC (unfortuntaly I use PLC). Sometime it happens continuously for a day or two and then I don't have anything for 3 month. I've never been able either to correlate it with RF issues and I leave in a non-polluted WiFi zone.

Oh well. I'm pretty sure I read another thread where people were having similar dropouts with synced players, and I think it was from some time ago so unlikely to be on a Pi4. I'll see if I can dig out that thread. The temperatures on my Pi4 now seem to be fully under control, and I do like the (subtle) speed bump. I should also add that Airplay and Bluetooth sync seem much better since I moved to pCP6 beta and RPi4. It could have been something specific about my previous pCP4/RPi3B+ setup, but I found that I had to regularly tweak the sync delay settings, especially for Bluetooth. That's no longer the case with my Pi4. chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=110765 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss

Just a thought - are you running the 'ShairTunes2 (fork)'? My mesh wifi has been running flawlessly for the last couple of weeks, but last night I had a recurrence of the 37-second dropouts. Rebooting pCP didn't fix it, nor breaking the synchronisation then re-synching, nor restarting every wifi AP. I hadn't changed anything in the wifi setup, but I'd been changing a few things in LMS, and on one occasion pCP booted without being able to start LMS or Squeezelite because I'd removed a mounted disk. I now suspect that the Shairport-helper *might* be the cause of the 37 second dropouts. I noticed that the dropouts coincided with shairport-related messages in the log file (which I stupidly didn't keep), so I disabled Shairport and the dropouts went away. Then I reloaded Shairport, and still no dropouts. If it ever happens again I will try the 'Re-Publish' or 'Wipe' options for the helper.

Seems useful - I can see the wifi signal strength indicator on my phone jump back up quite quickly as I walk away from one AP and towards another. Fortunately the SBR wifi doesn't seem to be affected by having fast roaming enabled, so it's only that Boom that needed to be wired, and since it's right next to a Gigabit switch that was easy to do.

Yes, I hadn't got around to restarting all the other devices that were connected to the old AP, so maybe one of those was blasting something nasty onto the airwaves. Still don't understand why the glitches persisted when I reinstated the Airport instead of the mesh, nor why the glitches didn't happen in the last minute or so of a track, even though they came every 37s during the song. I'm not going to lose sleep over it though - everything's been running fine since the change of SSID. It's a bit annoying that I've had to disable the 802.11r 'fast roaming' to allow the wireless Boom to connect. I might switch that Boom over to wired so that I can make the most of that feature.

Re: [slim] Player synchronisation problems with new mesh wifi
Well that's a relief - first thing I tried! I changed the SSID of the new mesh wifi, made a new wpa_supplicant.conf for pCP, and reconnected. The USB DAC now runs in perfect sync with the powerline (wired) Boom without glitches. I also connected the wireless Boom to the new SSID and that also runs in perfect sync with the other two players without glitches. If only I'd come up with a new SSID yesterday when I first installed the things I could have saved a lot of effort. chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=110765 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss

My backed-up image contains all the information about my original wifi hardware, so just works as soon as I power it up, provided I'm using the Airport Extreme. At that point, if I switch the Airport Extreme for the mesh AP, that's where I was when I first noticed the problem. If I re-image again while the new mesh AP is running, the image would still know all about the Airport. A fresh pCP image might be worth trying though - one that doesn't know anything about my Airport. I can see an evening of testing coming up.

Given how long the Booms continued playing after various LMS shutdowns yesterday, I suspect they're being sent compressed data, so that's certainly something to investigate. And I think you're right about the player sync data - when I disabled the 'maintain sync while playing' option they went noticeably out of sync much faster than every 37 seconds - even after a few seconds I could hear the difference. And given that that option made no difference to the glitches, the 37 seconds seems more likely to be related to buffer refills. But I can't see an obvious reason why they'd suddenly become an issue with the new mesh wifi? If the player signals that it needs a refill, is that message being blocked or delayed somehow? And why would this only affect playback when two players are synced? As well as trying the RPi wired, I'm also thinking I should completely remove and reinstall the wireless parts of pCP. I gave my new mesh network the same name as my old wifi network, so maybe pCP is remembering something about the old network that isn't suitable for the new one. Perhaps I should just give the new network a different name. chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=110765 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
