Problem with AirPlay with Mu-so

You could start with a factory reset.

Tried the factory reset and it had no effect.

Perhaps call the mu-so help desk. It's what they are there for. 

Thanks. Ill give then a call after the bank holiday.

The Airport Extreme is not Airplay enabled - Apple TV and Airport Express are. So depending on what devices you have, this might be an issue, depending on how your devices are connected to your network. What other devices are you trying to play to or from? The Muso, of course, is Airplay enabled, so it should still be able to play using its own Airplay input, but I suspect this is a network setup issue rather than a firmware problem.

Both Apple TV and my Mu-so are physically connected using rj45 connectors to the same AirPort Extreme. The Apple TV offers AirPlay, by the Mu-so does not. So I suspect it's got nothing to do with the AirPort Extreme. My iPhone sees all AirPlay devices except the Mu-so.

Not sure not sure what you mean by the AirPort Extreme not being Airport enabled. I know it can't be used as an Airport client (it doesn't even have any A/V output, so it would be impossible), but it does pass appropriate/necessary Bonjour packets that implement the AirPlay protocol. 

Zanc, I think Chris might have been referring to the AirPort Extreme being an AirPlay client.. which I don't think is relevant. I would use a network utility if you have one to see if your Muso is responding to Bonjour discovery packets. There is an iOS program called Net Analyzer that can do this.. It's really basic and limited but can do this... 

You should see a red B against the Muso in the app. If you don't see this you might want to try disabling IGMP snooping on the AirPort Extreme... I think you should see a setting for it in the advanced set up section. It might just spring into life (it's all about managing multicast groups on switch ports). If still nothing, then it does sound like something isn't quite right with your Muso.

Rob, ok it definitely sounds like that call to Naim is in order then.

A quick aside if I may - should IGMP snooping be enabled or not? Since turning it on in my Asus router, the Naim app seems to work faster on my iPad, with less delay to get the 'now playing' screen up, for example.

HH in a perfect world with everything working as it should IGMP snooping should be enabled, but invariably in our applications many are making or inadvertently making compromises on their home network, so the multicast protocols are not working properly.. Thetefore best then to disable IGMP snooping.

IGMP snooping is about managing multicast data efficiency so as to prevent multicast data being broadcast on all switchports. However the amount of multicast data we use for UPnP device discovery is tiny and therefore not much to be gained by its use. If you were multicasting hidef video it would be different.

IGMP itself, is something different from IGMP snooping... That is the ability to handle multicast data at the router level.. Best leave IGMP on, but keep IGMP snooping off for a happy life

HungryHalibut. MAGIC!! Turned IGMP on and the Mu-so became immediately visible. This should be stamped on the user manual.

Thanks again.

Well, that's put a smile on my face! I was actually asking whether I should have IGMP switched on... but the fact it's sorted your problem is brilliant. 

Rob, good it's working.. On my Apple Airport TimeCapsule I don't think I can turn IGMP off, I can only disable IGMP snooping. So if you you had IGMP off before, and now you have put that on and it's working.. It is worth trying to re-enable IGMP snooping.. And check both UPnP and AirPlay devices can still be seen.. If so, bravo, you have a correctly set up your LAN equipment in terms of optimum efficiency. If not don't worry for the reasons I said above. Please do report back.

It turns out that I hadn't actually enabled snooping, and everything seems ok. Out of my confusion comes Rob's solution. 

This, for me, is the best thing about the Forum - helping and supporting each other. People come at challenges from different perspectives and it's great when these irritating issues get resolved, and then we can share that learning going forwards.

Zanc, you're right, of course, about the AE, I was just trying to see how your network was set up, as I found it hard to believe the firmware was to blame. Anyway, good to hear you're now up and running. 

Thanks everyone, but my glee may have been a bit premature. A while after the Mu-so AirPlay was detected it dropped out. 

After some laborious experimentation is seems that AirPlay appears after the router is re-booted but then drops out if it has not been used for a while.

Although I cannot yet confirm it yet it doesn't seem to matter if  IGMP is on or off. It just requires a router reboot.

ill be a bit more methodical to identify the reasons for it dropping out

Ah well, it was good while it lasted. I use my Qb with a wire; is that possible for you? It's miles more reliable than wifi. 

I've tried wired and wifi options. :-(

In that case, I'd suggest you reset the Qb with the little pinny thing, plug in a wire from the switch that your NAS is connected to and see if it works. If not, the mu-so helpline needs to assist you. I plugged my Qb in, and it just worked, thank goodness. 

Well, I carried out a major reconfiguration of my network by moving the router next to the Mu-so, but left the Mu-so connected directly to the same port on the Airport Extreme (4th Gen), and now Airplay works and is stable. However, I do not know why the change worked, especially as the Mu-so is physically connected to the same port on the same Airport Extreme as it was before. I can only suspect there is a clash between other components on the network.

I'm not giving up on finding the reason for my earlier problems and will post back when I do find out.

Thanks to everyone who offered help and sympathetic comments.

I wonder if you have inadvertently solved the problem with the time honoured call centre method, turn it off, turn it on again. I apologise if that sounds a little facetious, but I have often found that a full network shutdown, followed by restarting one by one, router first, to be helpful, especially after changing any network settings. 

Chrissu, thanks but I did that many times. Spent about a week before deciding to post here. I WILL find the reason, as it's seriously bugging me why it was happening.

In the last two weeks for no good reason I have variously played music from my Synology NAS, Spotify and iTunes via my iPad to my Muso. The NAS via the Naim App works pretty well apart from some of the methods of access having no data. Spotify plays happily all of the time, but iTunes can be erratic. If I play music and use other applications they can interrupt or stop iTunes playing altogether which I find unacceptable from the company that controls the hard and software.

i suppose this might more rightly be posted on the Apple forum but do not really hope or expect a solution.
