View Full Version : Why would stuttering SUDDENLY start?

I've suddenly started having the same problem which has been posted a number of times: music playback through my wireless SB3 stutters through every song played. The thing is not one thing has changed from the time when it was working perfectly.

Running on a Win XP Pro SP2 system, Hawking wireless router, PC is wired to the router but SB3 is wireless. FW version 35, Slimserver version 6.2, signal strength 80%, buffer <= 10%. I'll probably move to FW version 43, but what I'd like to understand is WHY did this suddenly start happening?

This very same setup worked like a champ through the time I last used it (about a month ago - I've been on travel). At that time I could leave a huge playlist running for hours on end. Never skipped or stuttered on me once. When I started it up today it has been completely unable to play any tune without stuttering. The only program I'd installed since Slimserver is Tag&Rename, which has nothing to do with a network interface. Hoping to hear from anyone who could help me figure this out!

I read a post where the person who had the same problem said it went away when he reinstalled Slimserver. I've used Tag&Rename a lot on my music library, but told Slimserver to completely rescan my library before playing music. Is there any evidence that some kind of Slimserver problem can cause this stuttering?

I've been experiencing this also and I think it may be interference which is causing the buffer to drop drastically and the resulting stuttering. It drops from 90-100% down to <10. I can initiate the same effect by turning on the microwave, so I'm guessing that I may be getting interference from some other local source. I'm trying different channels on my router and have had a good run of no stuttering on the latest attempt...several days. Don't know yet if it's the channel change or the source of the interference has gone quiet.

My neighbor just got wireless and set it up on the same channel I was running on. Destroyed my good time. So I switched off that channel and all is well again.

edit: sorry that might be cryptic. Use your laptop (if you have one) to see if there are other wireless networks in your area on the same channel as your home wireless. Then switch your wireless to a channel no one else is on. [Also trade in your 2.4 ghz cordless phone for a 5.8 ghz one.]

I have my SB3 connected with 85mps Devolo Homeplugs and I also get stuttering occasionally. I see the network rate in the (Devolo) Microlink Informer drop from 58mbs to 1mbs even though the other devices are happily working at their normal rates. Seems to happen towards the end/start of songs so it may not be confined to wireless. It certainly is made worse by using a NAS.

The problem with those Homeplug type devices is that the signal is prone to interference from any device running on mains electricity in your house.

Typically anything with an electric motor will cause the mains voltage to become very "dirty".
I've also noticed that the long life light bulb I use around my house cause a lot of TV interference when first switched on.

I'm not sure how isolated individual houses are these days but I do remember that we used to get a lot of TV interference if a nearby neighbour used an electric drill. I think it's because the mains wiring acts as an antenna.

So you might find that an applance in your own home is not the source of the noise in your mains wiring.

I can only hope that's the problem. I downloaded Netstumbler last night and will give it a try. With luck I'll just be able to move to another channel.

Try the nettest plugin to prove the network capacity between the server and player [included in 6.5 or available on the wiki: http://wiki.slimdevices.com/index.cgi?PluginDiagnostics]

Hmm, I put it into my Plugins folder and restarted Slimserver. It now shows up in the Slimserver Web interface under Server Settings > Plugins, but it does not show up on my SB3. I checked under Plugins and Settings. Where do I find it?

I think I solved my problem. I upgraded to the version 48 firmware and everything appears to be back to normal. Buffer is at 90-100%, signal strength up to 90%. But I still can't figure out why version 35, which I had been using to this point, was working just as well until it... didn't.

Should be a new menu under plugins on the player UI. Anyway, now you have fixed it doesn't matter...

Maybe your neighbors got wireless! Or someone got new cordless phones.
Seriously, it was kind of the same thing with me, I was using a wired SB
with a wireless bridge. Worked fine for a while. I did change my setup, so
it's possible I was getting reflection/refraction from the cabinet of a new
amp I put in, but it's also possible that it was just interference. IMO,
wireless is great for e-mail & websurfing, but for streaming AV I prefer
wired. In my case, it was easy enough to throw in a switch and go wired.

The stuttering was caused by a subtle timing bug on the PCI bus between the processor and wireless card in the squeezebox. This affected some players more than others when using the beta firmware versions 29 to 40. This was fixed in firmware 41.

I hope that helps to explain the problem.

I've been experiencing the stutter problem with 6.22 and firmware 48, so it is not necessarily related to the this bug. I've gone about 5 days now with no stutter after trying several different channles on my router.

Maybe you should also check the isolation of your microwave (for health
reasons...).
I have no probs with my wireless while using the microwave.

I have this (or similar) problem with a wired SB3 and devolo homeplug. NetTest plugin is absolutely fine for over an hour, but playing music will start to stutter within a few minutes nearly every time. Not sure how this could be due to dirty mains.

I have been running some tests over the last few days. My SB3 is wired via Devolos to the router. From there I have a choice of Dell high performance PC, Qnap TS-101 and ReadyNAS NV. All three have identical FLAC music files and differ only in processing power and memory (hard disks aside). The best test is to run Random songs (200 ahead, 5 back) as this really puts pressure on the processor. In fact if you skip forward a song you will invariably get stuttering or a pause because of the way Slimserver creates the random list.

On the PC I get a very short silent blip, on the Qnap and NV I get up to 10 seconds of silence (it varies) before music resumes. Same thing happens with stutterting on normal play. It only happens occasionally but is it worse and more frequent on the NAS's than the PC. So my view is it is a bug and related to processing or memory requirements.

What is slims response to these issues? Is it always someone elses fault?

At the moment i have an SB3 sitting there pretty much useless.
