Streaming to airport express causes majour crashes.

I finally got an express for the sitting room hifi.
My music is on a NAS drive and the I access it from an iBook.
iTunes loads fine and the music is there. If I play the music on the iBook its OK, with just an occasional dropout which rights it self.
On the Airport though its unusable, the tune loads fine and gets started, after about a minute, you get one drop out, then more and if you try and do anything on iTunes it crashes, force quit does not quit iTunes, it has taken the whole system down you cannot load activity monitor or anything.
It does this each and everytime, any ideas?
The wireless side is handled by a Draytek Vigor 2600, which seems to do the business on most things, even though itunes crashes, the NAS storage device is still accessible from the desktop no problems.

My problem is exactly the same. Only iMac speakers work stably.

Airport express causes router crash

My air port crashes my wifi network. I am trying to connect the airport wirelessly to my Mac solely for AirPlay. Also, my Mac does not "see" my airport express? Help, please!,

When the AirPort Express is configured for AirPlay, it simply "joins" the existing wireless network....just like a computer or any other wireless device would join a wireless network.
It's hard to imagine how this would cause a network to crash...but I suppose anything is possible.
Here's what we do not know.....and need to know to provide some help.
1) What version of the Express that you have?
Locate the model number on the side of bottom of the Express and post back with that info. The mode number will start with an "A" followed by four numbers.
2) What version of operating system your Mac is using?
Click the Apple icon in the upper left corner of the screen, then click About This Mac to see the OS X Version number. Post back with that info.
3) What device is providing your wireless network now?
Make? Model Number?
4) What type of wireless security setting that the current wireless router is using.?
The Express is expecting a setting of WPA/WPA2 Personal. If your wireless router does not use that type of setting, the Express will not connect.
With some basic information, we can begin to troubleshoot the problem.

IMac (on Ethernet) Can No Longer Stream to Airport Express (on WiFi)

After years of reliable service, all of a sudden I cannot stream music from iTunes on my iMac, via my Airport Express, to my stereo system.
First, a bit about my configuration:
   * iMac connected via Ethernet to a wireless router (D-Link DIR-655).
   * iMac Airport (WiFi) is turned off.
   * D-Link sets up a wireless network, and Airport Express joins the network.
   * Airport Express does not set up its own network, it's simply a client of the existing D-Link wireless network.
   * iTunes "sees" the Airport Express, and can stream audio via AirPlay.
   * iPad also joins the wireless network, and also can stream to the Airport Express via AirPlay.
   * iMac running 10.6.8, with all software updates applied.
   * Airport Express running latest firmware (7.6.1).
Well, that was a few days ago, when "it just worked". But for some unknown reason iTunes could no longer "see" the Airport Express.
So I took my Airport Express to the Apple Store and they did a Factory Reset, but it did not solve the problem. I figured my rather old Airport Express was failing, so today I bought a new one. The symptoms have changed a bit, but even after spending an hour on the phone with AppleCare, it doesn't work properly.
Now, the only way the iMac can stream to the Airport Express is if the iMac also joins the wireless network. In fact, now with Airport turned OFF on the iMac, the Airport Utility cannot see the Airport Express. But here's another weird thing: when I use the IP address of the Airport Express, the Airport Utility CAN connect with and manage the Airport Express, even with Airport turned OFF on the iMac!
I should also mention, the iPad has no issues whatsoever connecting to the D-Link's wireless network and streaming music to the Airport Express.
This all seems like something might have changed on the D-Link wireless router. But for the life of me, I cannot figure out what setting(s) on the router might allow the iMac - over Ethernet - to stream audio to the Airport Express.
Another thing. When I have Airport turned on on the iMac, it can "see" and stream to the Airport Express, but the music has very frequent drop-outs. Could this be related to the fact that the iMac has two IP addresses (one on Ethernet, one on WiFi)?
My goal is to get things "back to normal", where I can turn off Airport on the iMac, and all LAN and WAN traffic from the iMac goes over Ethernet. I have a few questions (for now :-)
   * Since my iMac has two connections to my LAN using two IP addresses (Ethernet & WiFi), is that likely to cause any issues?
   * When two computers join the same wireless LAN, can they effectively talk directly to one another, or does the wireless router need to be involved every time one computer sends a TCP or UDP packet to the other?
   * Do routers (or the DIR-655 in particular) tend to have any firewalls or policies that control connections on the LAN between Ethernet and WiFi clients?
   * Since AirPlay uses TCP port 3689 and UDP port 5353, would the DIR-655 need any special configuration to "open these ports" so an Ethernet client can connect with a WiFi client?
So, any help would be most appreciated!
Thanks!
Jim

I am having a very similar issue. I use my Airport Express (AX) to stream music from the computers on my network to my stereo via Airplay. I have AX set up to wirelessly join my existing wireless network, which uses a D-Link DIR-655 router hooked to a Time Warner cable modem. I can succesfully connect all of my wireless devices via Airplay, through iTunes to my AX, including two laptops and an iPhone. However, my primary desktop PC, which does not have a wireless card is linked directly via ethernet cable to my D-Link router, and it is not able to see my AX. Similar to your case, I can see the Airport Express from my PC through my Airport Utility by directly typing in the IP address. Note that the AX set-up option to allow Ethernet clients is checked. I also noticed that my laptops will stop detecting AX if I directly connect them to my D-Link router via Ethernet and turn off their wireless cards. They will resume detecting AX when I turn their wireless connections back on. I have tried every conceivable setting of my D-Link router to no avail.

Airport express causes iphone and ipad to lose wifi

We have a new (3 months old) Airport Extreme in our house. It provides internet connectivity for an iMac, macbook pro, iphone 3gs, and ipad 2 (and a pc). Never had any problems.
Two days ago, I purchased an Airport Express to put downstairs, and wirelessly extend the wifi network. Setup seemed to go smoothly, and all devices reported a stronger signal downstairs. However, the iphone and ipad started behaving really strangely after an hour or so. They kepy saying they couldn't connect to the network, and even when I selected the network, they kepy saying the password was incorrect (even though I typed it in 10 times). I reset the network settings on the iphone, as well as powered it off and rebooted it to no avail. The only way I have been able to get things working again is to unplug the airport express; restore the airport extreme to its factory settings, and then re-set-up the network on the airport extreme from scratch.
After things were working again, I re-installed the Airport Express and configured it to wirelessly extend the network. Same thing happened: everything was fine for an hour or so, and then the iphone and ipad lost wifi connectivity and wouldn't re-connect. Only way to fix it was again to unplug the airport express and wipe the airport extreme back to factory settings and rebuild the network from scratch.
Is anyone else having this issue? I'd really love to use the Airport Express for its advertised functions of extending my wifi network (and streaming itunes on my stereo downstairs)-- but if it garbles or kills the ability for my iphone and ipad to use Wifi, that's unacceptable and it will be going back to the Apple store.
I should mention that as far as I am aware, I have the latest versions of ios running on the iphone and ipad, and the latest firmware updates for the airport extreme and airport express.
Has anyone dealt with this problem?
Many thanks.

Problem solved, found Ninja10's post and was able to fix this problem. Thanks Ninja10!

Problem solved. I was recommended by a non Apple consultant to manually change the radio channel. Channel 11 worked.

Apple TV and Streaming to Airport Express

Hi I am new to all this and had a question about apple tv before I go ahead and purchase.
I would like to sync all my music from my itunes account on my PC to the apple TV.
What I would then like to do is be able to turn off my PC and still be able to stream music from the apple tv to other stereos around the house via airport express units whilst being able to control these units by the app on my iphone... is this possible or does my PC still need to be switched on? I have asked in the apple shop and no one seems to fully know!
Also can more than one iphone (mine and myt wife's for example) be able to remotely control music around the house from 2 different iphones? or will only one work at a time?
Sorry if this sounds stupid but really need the answers before I spend money on the kit.
Thanks

Would you recommend this set up
i would. i've got one of the original 40 GB units and it is probably the most-used gadget in my arsenal.
other users here will probably try to sell the new mini to you (due to it has an HDMI interface and whatnot) but IMHO nothing beats the ATV for ease-of-use.
Is there a new Apple TV coming out soon or should I just go ahead and get involved!?
there's rumor out there that a new model is in the pipe. however, nobody here would know when it is due and what features a new model will pack.
if you have the budget, go for it

Outputing Raw Stream via airport express

What is the output of the airport express optical port? Is a raw stream of the original audio file? thx

For the AirPort Express (AX), audio input is primarily provided by iTunes. Of course, it can also get input from other sources like Rogue Amoeba's Airfoil.
iTunes does most of the work. When iTunes plays back standard audio content (AAC, MP3, audiobooks, Internet music streams, etc., it decompresses those file formats and creates what's essentially a raw, uncompressed audio stream. That stream is compressed using Apple's Lossless Compression (via a QuickTime codec), encrypted, and then, streamed (via AirTunes/AirPlay) to the AX. The AX decrypts the stream, decodes it, and outputs it in either analog format or as a digital PCM stream.
If iTunes is playing back a digital multichannel file format like AC3 (Dolby Digital) or DTS, those bitstreams (like the lossy formats) are wrapped in Apple's Lossless compression, encrypted, and then, streamed to the AX. In these cases, the AX would first decode the stream, and then, output the raw AC3 or DTS stream via its optical digital audio port.

Coding audio streams to Airport Express?

Not even sure where to post this question, so my apologies if this is too far off topic.
I'm very curious about the audio coding that happens when streaming music from iTunes to an Airport Express, or, a 2nd gen AppleTV? Is there any additional code-decode going on when streaming? Playing a 44.1 kHz .wav file, uncompressed, and capture that waveform at the electrical out of Airport Express... will it be identical to the original .wav file (ignoring some minor D/A artifacts)??
Many thanks in advance.

Can you reference a link or 2 where I can read a bit further?
I'll see what I can find as Apple has provided very few details on this. The links I had to some material I had reviewed earlier, unfortunately, are no longer valid.
For example, what happens with an uncompressed .wav file that is an 11kHz sample rate? Does the AX have a D/A that supports all of the supported sample rates? Or, is that part of the compression "on the fly" into Apple Lossless that everything is coded / converted into a single sample rate (44.1 kHz??).
Great question!
The AX works only with iTunes v4.6+ and is limited to music files that iTunes can read; ie, 16-bit data only. (An exception is you can use a third-party product like Rogue Amoeba's AirFoil to stream other non-iTunes sources.) These data, though, can be in any file format that iTunes recognizes, from lossy MP3s at the low-quality end of the spectrum to Apple Lossless and lossless AIFF or WAV files at the high end. To more directly answer your questions, the AX functions only at a 44.1kHz sample rate. When you play, for example: 11kHz, 32kHz or 48kHz data, iTunes sample-rate-converts the data in real time before sending it to the AX. As you figured this is a limitation of the QuickTime Codec that is the heart of iTunes.
One operational glitch, that primarily affects the analog side, is the fact that the AX doesn't have a local clock circuit. When the incoming data is interrupted, as it is when you change songs in iTunes, there is no longer a digital output to feed the DAC, which loses lock as a result. Provided you can live with its limitations the combination of iTunes and an AX provides an easy way to pipe CD-quality music around your home.
FYI. For the 802.11b/g version of the AX, the analog audio is handled by a Texas Instruments PCM2705 digital-to-analog converter. I don't know if they used the same DAC for the newer 802.11n model. Some audiophiles use an external DAC in an attempt to overcome any of the AX's shortcomings.

Apple TV sync disrupts AirTunes streaming to airport express

Whenever my Apple TV is syncing with iTunes it disrupts my AirTunes stream to my airport express - the audio just stops playing.
Is there a way to fix this? Perhaps slow down the Apple TV sync so it doesn't suck up all the bandwidth so my airtunes stream keeps playing? Not sure if that's really the problem though.
Thanks for the help.

Yes, they ditched this useful feature with AppleTV2.

ITunes doesn't stream to airport express remote speakers

Hi,
Since I updated iTunes (v8.0) I can't stream audio to my remote speakers via airport express.
The remote speakers are visible in iTunes, I can select them but airtunes can't connect. I don't get an error message, after a few seconds iTunes plays the music with my PC speakers. I did a firmware update for AX and had the latest version of the airport utility. I did a hardware reset and reconfigured the AX. I disabled the firewall. Nothing helps... Any suggestions?

The next time you are in iTunes, click on the speaker icon at the bottom of the screen. You should be able to see your remote speakers and your computer speaker. Click so that both are on. Can you connect?

Error -15000 when streaming to AirPort Express base stations

I have the latest iTunes 8.0.2
The firmware updated to the latest in AirPort Express
PC: Windowds XP, SP2
When I try to stream music to AirPort Express from Itunes I get Error -15000
I have tried everything according to the support pages with no success. In some support pages the solution is only for Mac. How do I solve this problem for PC with Windows XP?

Welcome to the discussions forum divonka.
I realize those documents refer to OS X, but I'd suggest your problem is similar. Try disabling your Windows firewall. If that works, find a way to open UDP port 5353 as explained in this document. Hope it helps!

Stream to airport express devices simultaneously

I currently have two airport express units in my house. They were purchased 2 years ago within 6 months of each other. I have them currently connected as one network. However I can not figure out how to stream Itunes to them simultaneously. Whenever I open Itunes the only options on my dropdown list are computer, living room (express #1) and office (express #2). Please help with instructions or suggestions.
Thanks

I found the update necessary to make the airport stream to multiple units.

Stream to airport express other sources than itunes

I would like to stream some other sources than itunes to my airport express. Ideally any thing that would other wise be played by my pc speakers.... i.e. YouTube etc....
Can we do that? NAy idea where I could get the software?
Question for MAC & Window based PC
Thx for ideas !

Check out Airfoil. That streams sound to Airport Express. Because of the way the Airport Express processes the sound, there's going to be a delay, especially if you're planning on watching Videos.
The guys that make Airfoil, say they've fixed that issue with Version 3 that will be out soon. No word on a release date. Here is the website.

Sound breaking up on Airplay if I stream to Airport Express and Apple TV

I have recently bought an Airport Express and latest Apple TV. Both are running nicely on my network, and I can use Airplay to stream music to either from my iMac, but if I try to stream to both then the sound breaks up? Can anyone advise why and how to fix this? Could it be my wireless network isn't up to it (11g)
Many thanks for any advice!

I am not sure this is entirely relevant but since I found these discussions helpful when I had a similar problem here is my two penn'orth.
We have a complex system with two Airport Extremes and 4 Airport expresses of various vintages. One of these was an old (meaning 'g' only & needs Airport Utility 5.6 to service) one, but this had wireless set to 'off' and only served to stream sound to the house HiFi. This one and all but one of the others were roamed (that is Ethernet cable connected), as is the Mac Mini House server (other machines are WiFi).
Breaking up (& other intermittent network issues) only seemed to start with Maverick. I solved this very persistent problem by replacing the old Express with a new one (in fact replacing one of the others and using that). I could conjecture that this had been the only node on the network not capable of GE (though some devices like webcams are not either), but I do not see why this was important.
I still think this rather strange - even the presence or absence of high-data services like eyeTV Netstream made no difference. But having solved it I should not complain - though it would be nice to understand it. It would also be nice if the Airport Extremes included a sound port...
All the Airport devices had been carefully set up according to Apple's default recommendations - so yes some might use 5GHz, though shutting this down did not help. (they still are).
Hope this helps someone!

Enough bandwith to usa a NAS server for itune & stream via Airport Express?

Hi,
i posted this question in the itunes forum, but got zero feedback. i was hoping someone here could possibly answer my question :
I was thinking of getting a ByteCC LANDisk NAS to use as an itunes music 'jukebox' server for 2 macs (a G5 and a macbook). I have a Airport Express that i'd like to use to stream music to my living room stereo via itunes,
My question is is there enough bandwith to stream from the NAS server to the macs, and then to also stream the audio to the living room stereo via the airport express at the same time?
I'm sure someone must've atempted this set up
Any help or info is apreciated!

This works. I have a WD Netcenter (320G) which I store my main iTunes library on (holding down the command key when starting iTunes allows you to chose which library you want to use). I'm not using an Airport base (D-Link and now a Zyxel) and I can stream music AND video no problem - all my movies are on there too and they play fine through Front Row.
Oh and I usually mount it as nfs rather then smb - handy little apple script for this which I run as an app (when are Apple going to bring out a proper location manager that automounts networked drives etc based on where you are?!!!).
Have fun.

Audio stream from airport express while watching a music video on laptop

Hello,
Can anyone help with instructions to have the audio portion of an itunes purchased video stream across the airport express while the video plays on the macbook. It seems to work fine with all of the music files but in trying to watch a video i purchased the audio will only play through the macbook. Any help is appreciated

Hello ehende2. Welcome to the Apple Discussions!
Sorry, but you won't be able to do this as this is a limitation of iTunes/AirTunes.
(ref: iTunes: Movie sound does not play through AirTunes)
