Your underlying problem is still there. BBC plays AAC and since Boom is in the sync group - you are transcoding so you may be straining your processor and network - in those circumstances the master player can affect things. Performance will also vary if you are playing live BBCiPlayer vs Listen Again. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=108101 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] PiCodePlayer + piZero + justBoomAmp zero poor synch
Let's not get hung up on the percentage value. This is what the people who write iwconfig have determined is the most meaningful way to report WiFi connection strength. There are other measures, but anything reporting 60% should be usable. -Transcoded from Matt's brain by Tapatalk- -- Hardware: 3x Touch, 1x Radio, 2x Receivers, 1 HP Microserver NAS with Debian+LMS 7.9.0 Music: ~1300 CDs, as 450 GB of 16/44k FLACs.

The only real deal is the pure db not any percent from something your AP or Nic could deliver. Link Quality itself is just how much interference is on your link. Signal Strength is the other thing to look at - you need to look at both values if you want to know whats going on.

Re: [SlimDevices: Unix] PiCodePlayer + piZero + justBoomAmp zero poor synch
Synching with hardware squeezeboxes is a tough case. Is that Boom wireless or wired? First and foremost I would use the same medium for both, so that network latency is consistent between players. Once both are on wifi make sure network strength is "very good to excellent" for both. 60% is not good. It's ok for fetching data like web pages but for a stream I'd rather see 80% If not enough, I would try to set Prefs > [Players] > Synchronize > Minimum Synchronization Adjustment (ms) to 100ms in both, leave delays to 0 and network latency to default. I think software players, even PCP, do not react in a very deterministic way to step requests, so such adjustments have a tendency to make the situation worse. Of course this means players can sit 99ms apart for hours, so if this creates noticeable echo, you'll want to lower that value as much as possible. I can say that over a rather poor ethernet network 4 Pi3s with justboom amps running pcp 3.2 will keep sync within 100ms (some echo sometimes). The same with good networking (upgraded switching hw, dedicated VLAN) can stay within 10ms the whole day it seems. 3 SB 3 Libratone Loop, Zipp Mini iPeng (iPhone + iPad) LMS 7.9 (linux) with plugins: CD Player, WaveInput, Triode's BBC iPlayer by bpa IRBlaster by Gwendesign (Felix) Server Power Control by Gordon Harris Smart Mix, Music Walk With Me, What Was That Tune? by Michael Herger PowerSave by Jason Holtzapple Song Info, Song Lyrics by Erland Isaksson AirPlay Bridge by philippe_44 WeatherTime by Martin Rehfeld Auto Dim Display, SaverSwitcher, ContextMenu by Peter Watkins. epoch1970's Profile: http://forums.slimdevices.com/member.php?userid=16711 View this thread: http://forums.slimdevices.com/showthread.php?t=108101 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] PiCodePlayer + piZero + justBoomAmp zero poor synch
What areyou playing ? If it is AAC then if Boom is part of sync group - LMS will transcode to Flac which will put a load on processor as well as increase network traffic. Use info to track the problem. Not sure about pcp but usually "cat /proc/net/wireless " gives detail info on wifi - noise level is as important as quality. Are there many discarded packets ? Wifi can operate at different speeds - what speed is your interface runnign at ? ( somehting like "iw dev wlan0 link" might tell you) Any message in LMS log. If nohting above then enable squeezelite logging - check is it a sync problem or a network problem. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=108101 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

The house has 2 wifi points, upstairs and down, the upstairs has attenuated antenna and seems pretty robust, but I'll move it right next to the 2 players having an issue to rule out network issues. The server itself is wired so should be fine. slingshotx's Profile: http://forums.slimdevices.com/member.php?userid=65803 View this thread: http://forums.slimdevices.com/showthread.php?t=108101 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Not 60% of "something" eg. i had some issues with my wlan setup in my old house. After we moved to another location my former poor wlan was quite good. Now some new Neighbours arrived and my wlan was bad again. Wlan is always (unless your in the middle of nowhere) not in your own hands. Now i*ve upgraded my wlan to a better (more antennas) setup and changed all my USB thumb Nics to Realtek Semiconductor Corp.

Re: [SlimDevices: Unix] PiCodePlayer + piZero + justBoomAmp zero poor synch
The wifi signal is around 60% so not too bad. I don't get any drop outs. I can temporarily put the router right next to the players to rule this out. I dont limit the bitrate, the problem seems worse on low res spotify streams than locally stored flac. Interestingly the amount its out varies I spend some time setting the audio delay between the devices only to find next time I play something its slightly off again. slingshotx's Profile: http://forums.slimdevices.com/member.php?userid=65803 View this thread: http://forums.slimdevices.com/showthread.php?t=108101 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

How's the WiFi signal there? Most likely network issues.

[SlimDevices: Unix] PiCodePlayer + piZero + justBoomAmp zero poor synch
Hi I have a few players, boom, PI3 and a duet, all PcP players on 3.20. I added a piZero Wireless and justboom Amp zero and a ceiling speaker in the loft for the bathroom. Works really well and I synchronise it to power on with the boom in the bedroom; however it is the only one of my players that doesn't either start in sync or stay in sync correctly. Has anyone else tried this? Is the clock on the pi Zero a bit iffy or is there a setting I'm missing? Maybe I should have spent the extra and got a Pi3, but the zero seemed like a nice compact solution for an extra player.
