Horrible playback issues with iTunes 8 and Airport Express over Wifi

Hello folks,
I just upgraded to iTunes 8, and since then, I've been unable to get good playback from my Airport Express with iTunes on my Macbook Pro.
I get between 5-30 seconds of continuous playback, then a hiccup, ad nauseum, ad inifintum. A five minute track usually ends up taking six-seven minutes to complete, and it's like listening to a CD skip.
Both the Macbook Pro and the Airport Express are communicating over 802.11n, and worked well before the upgrade to iTunes 8. On my older, slower, crappier Powerbook which only has 802.11g but runs iTunes 7 (in the same room, about two feet from the other laptop), playback is rock solid.
I've noticed when I monitor the WLAN interface on my MBP with 'netstat -in', I'm seeing a lot of Ierrs, but there's nothing in any of the system logs to indicate a hardware problem (yet, anyway).
Has anyone else had this issue since upgrading? Should I be looking to get my WLAN NIC fixed, or is it an issue with iTunes 8? Are there diagnostic applications I can use to perform hardware confidence tests on the WLAN NIC?
cheers,
Klaus

My AirPort Express optical out has this problem as well, stutter and very bad sound. But only the new 802.11n modell. A older 802.11g model works without a problem.
It worked well until I upgraded to iTunes 8, I bought in in May.
I just had my AirPort Express 802.11n replaced under warranty by Apple but the new unit has the same problem.
Everyone who is using the optical out and have the stutter problem needs to write to Apple about it so they realize it's a problem and fix it.

Using apple remote with iTunes 9 and airport express/remote speakers

Hi,
Does anyone know why the apple remote will control the hardware volume for the speakers on my mac, but when playing via the airport express connected to remote speakers why doesn't it control the volume slider in iTunes?
This would be really useful as at present I need the apple remote to control track selection and play/pause, but another remote to control volume.
If it isn't possible now, can Apple please add it to the pile of suggestions for the next version build of iTunes?
Many thanks

Installation issues with Time Capsule and Airport express

I hope I'm not over sharing, but I want to get as much info out as possible.
I just purchased a 4th generation Time Capsule and have two 1st gen Airport Expresses, which have always worked flawlessly. The TC is about 6 feet from the cable modem, the first Express is about an additonal 15' away pluged into the power strip with the entertainment equipment. The second AE is an additional 20' further. When "trying" to use the internet via wi-fi in my office, even though the icon on the top of the screen & airport utility shows full connectivity, but in reality I have very slow or no wi-fi.
The TC wireless mode is Create a wireless network, internet connection sharing - share a public IP addressand. Both the AE's wireless mode is Extend a wireless network. The internet correction - connection sharing is off.

Your TC replaced what?
Are you extending on 2.4ghz?
There is a chance the TC is lower than the router it replaced.. you may need to get the second Express closer to get a good signal so it can extend properly.. the idea is to have the express in about the centre of signal strength not distance.. use your laptop if you have one with a wireless analysis program like istumbler to find the signal at the TC from say 3M.. at the express 1 and at the express 2. Work out if the signal is too low and move them as appropiate.
Or.. think the arrangement and use something like EOP adapters direct to your office.. they can work hugely better than wireless. (or just as badly.. depending on the house wiring).

Is the Time Capsule wi-fi router compatible with the Nest thermostat? I've read where there are issues with the Nest and Airport Extreme (AE)? Is AE used in the Time Capsule?

I've read where there are issues with the Nest and Airport Extreme (AE)? Is AE used in the Time Capsule?
If so, i already have a wi-fi router, so can the Time Capsule simply be used for wireless backup instead of as a router if there is conflict?

A TC is fundamentally a AE with a sata chip included to drive the hard disk. Some slightly different bios to include disk functions, although most of those are also on the AE. So as a router it is 99.999% identical.
And yes, if you have another router you can easily bridge the TC and use wireless for backups and internet connection. Once you no longer route through the TC the issues with most NAT problems including port forwarding should disappear.. mostly this is due to all apple routers using NAT-PMP instead of upnp which is the near universal standard for opening ports.. without upnp apple keep their routers more exclusive.

Apple TV Inference with Time Capsule and Airport express?

I have recently bought an Apple TV 2, which seem to be working fine, however since installing it on my wireless network both my Time Capsule and Airport Express can't be found. Following some fault finding it seems that when I unplug the Apple TV I can reconfingure the TC and AE.
The TC and AE are configured to join my existing network....and have happy sat there for a few years.
I would really welcome any ideas.
Thanks

Welcome to the discussions!
It sounds like you have the basic configuration covered correctly.
You might want to check some settings on the TC:
Wireless Mode would be create a wireless network
"Allow this network to be extended" should be checked
The AX should be set to "extend a wireless network"
The "allow wireless clients" box should be checked
In this configuration, the ethernet port on the AX is active so things should work.
A minor point...Although the TC is a dual band device, the AirPort Express is not. Can you make sure that that the Express is connecting to the "main" network on your TC? The "guest" network cannot be "extended".
If you place your laptop close to the Express and hold down the option key while you click on the AirPort icon, some connection information will be displayed. The MAC address of the device that the laptop is connecting to will be indicated. Make sure that that this is the MAC address of the AX, and not the TC.
Another note...If you have not changed the default "main" network, the radio mode is broadcasting 802.11n only at 5 GHz. These higher frequencies are absorbed by walls, ceilings and any obstructions much more quickly than 2.4 GHz signals. So, if you AX is some distance away, you may not be receiving a strong signal for the device at that location.
If you have a signal strength utility on your laptop (the "bars" at the top of the screen are not a very good indicator of actual signal strength), turn off the AX and take a reading to see what kind of signal the Express is receiving where it is located.
Please post back with your results.

I need a new modem. Which modems work well with MacBook Pro and Airport Express?

You need to inquire from your ISP which modems are compatible with their netwrok. They should give you a list.

Audio Playback issues with quicktime 7 and iTunes - distorted sound

I was informed by my Soundcard manufacturer that Quicktime7 now requires a "real" WDM driver.
Many soundcards seems to have a "fake" WDM driver and this leads to chopped up sound that is completely distorted / garbled and impossible to listen to.
The fix is to downgrade to an older version of quicktime and iTunes.
I'm posting this because it was driving me crazy that there is no information on this in the support pages from Apple even if there are plenty of reported issues with audio playback. The system requirements from Apple does not mention the WDM driver either. I am not sure if this "true" WDM driver has to be "windows signed" and all unsigned drivers are "fake".
I'm sure the changed requirements has changed because of the need to address more audio channels but it would be great if the "safe mode" would accept "fake" WDM drivers.
I have also requested a driver revision from my soundcard manufacturer. We'll see...

By way of experiment, try updating your QuickTime Player to the most recent version.
Does that help with the iTunes problem?

Issues with Windows firewall and Airport Extreme

Hi all,
I'm having some issues with my Airport Extreme and Windows Vista firewall. I've got the most current versions of all the airport express software and firmware. My iTunes can see the remote speakers, and I can access the airport extreme using the apple-supplied admin software, so I know that they are working and on the network.
However, when I try to stream music through iTunes, the speakers won't connect. (yes, I have the "stream-music" option checked) However, when I disable windows firewall, they work fine. Therefore, the issue seems to be with a specific port that is not open through windows firewall. When I checked the exceptions for windows firewall, all the associated apple software is listed as exceptions. I think that there is one more port open that I do not have.
Any thoughts?
thanks.

AirPlay/AirTunes is based on the ROAP protocol. I would suggest trying the following ports:
Add TCP 443 for SSL
Add TCP/UDP 554 for RTSP
Add TCP 3689 for DAAP
Add TCP 5000, 6000, and 6001 for ROAP
Add TCP 5297 for Bonjour
Add TCP/UDP 5298 for Bonjour
Add UDP 5353 for Airport discovery
Add TCP/UDP 7070 for RTSP
Add TCP 8000-8999 for iTunes radio streams
Add TCP 42000-42999 for iTunes radio streams

Playback Issues with multiple framerates and Blackmagic Decklink 4K Extreme

I recently swapped by AJA Kona Card for a Blackmagic Decklink 4K Extreme in order to get external monitoring in DaVinci Resolve.
I'm working in a 1080p 23.976 project that includes some 29.97 SD and HD footage. When loading this 29.97fps footage into my source footage, I periodically encounter frozen playback (The play triangle in my toolbar becomes a square symbol and remains that way). From there I am unable to playback any footage in any timeline, and requires a full system shutdown to return to normal! The problem is seemingly intermitent, with successful playback happening sometimes.
The 29.97 footage was DVCPRO, I attempted to transcode to Prores to troubleshoot. No dice. I believe it to be an issue related to the Decklink's inability to handle multiple framerates on-the-fly but wanted to submit here, too. I've also experienced intermittent sync delays on my broadcast monitor.
Decklink Driver 10.0
Premiere CC 7.2.1
Mac OSX 10.9.2 (same problem pre-mavericks)

Hi Andy,
You should not have any issues with Blackmagic handling multiple formats on the fly. However, I believe the frozen playback issues your describing is related to the Desktop Video 10 driver. I suggest rolling back to 9.3.3 for the time being. Blackmagic is looking into this issue now.

Issues with itunes/icloud and music on my Iphone 5 and PC

I had to set up my laptop (windows based pc) as my main itunes device because my desk top died. I installed intunes (the newest version and icloud as well.) thought I had everything set up. I then redownloaded all the purchased music from the itunes store and also moved all my own music (cdpurchases for many years) from an external device to the laptop and put it all back into itunes. I set up all my playlists the way I wanted to and then synced my phone (with the new IOS 7) to the laptop. when I got finished syncing my phone all the music appeared to be on my phone yet a lot of it had the cloud next to it and most of that did not have the album art that I so painstakingly over numerous hours made sure was on each album. Itunes used to let me cut and paste album art that was not available from itunes into the get info section but now no matter what I did it would not install. I was playing my music at work yesterday and a lot of the music with the icloud next to it would stop and start repeatedly. I got home and deleted Icloud from my system which of course disabled the find my phone function. but when I synced my phone after, it installed all the music and the album art. Has anyone else run into these issues?? Were you able to fix the problem without deleting Icloud?
I think Icloud is a great idea but execution *****.

The songs listed in your iTunes library as "iCloud" probably refer to songs in "iTunes in the Cloud", meaning they can be re-downloaded from the iTunes store from the Purchased list on your phone. They are not in your personal iCloud account and do not automatically sync to your phone using iCloud.
If you want to download this music to your phone, open the iTunes app, tap More at the bottom, tap Purchased, tap Music, tap Not on This iPhone at the top, then tap the download symbol (cloud with downward facing arrow).
If you don't want to see the "Cloud" designated music in your iTuens library, you can turn this off by going to iTuens Preferences>Store and unchecking "Show iTunes in the Cloud Purchases".

Playback issues with iTunes Match on iPhone 4 (iOS 5.0.1)

I'm running into several odd issues when playing songs on my iPhone with iTunes Match enabled. The problems I've experienced are:
A song partially plays, then skips to the next song.
Sometimes songs will not pause, pause after a 2-3 second delay, or pause, then start playing again when I press the pause button.
Sometimes there is a 3-5 second delay when playing songs that have already been downloaded.
Sometimes a song will play distorted, it just sounds like static.
Once, I pressed play on my iPhone and it just started playing random songs, some that had not even been downloaded before.
A few times, when I pressed play on already downloaded songs, nothing happened.
Now, some notes about these problems I've been having: I have a mix of matched, uploaded, and purchased songs. I haven't found a pattern as far as the type of songs that any of the issues occur with. With problem 1, I can kind of understand this happening if the song hasn't completely downloaded, but this happens even for songs that I've downloaded. It doesn't always skip the song in the same place and I can even go right back to the same song and play it all the way through again with no problems. With problem 2, it seems like maybe I'm just being impatient here, however, I'm not sure why there's a delay when these are downloaded songs and the artwork has already been downloaded. Sometimes if I just wait about 10-15 seconds it will finally start playing, but again, that seems odd since I've already downloaded the song. Problem 2 and 3 are kind of similar. I've noticed that sometimes when this happens that I can see the "network processing" indicator in the status bar, but sometimes not. It's a little odd to see my iPhone going out to the network to play a song that I have already downloaded and have the artwork (assuming metadata as well) for the song. Problem 4 has happened just a few times, but usually happens immediately after I unpause the song or start playing a song. Again, I can go back and play the same song normally and have played the same song before previously. Once, it caused the Music app to just crash entirely. Not much to say about problem 5 other than I checked shuffle and it was off. Just a little odd. Not much to say about problem 6 either other than it hasn't happened in a few weeks now.
Sorry for the wall of text, but it just seems that there are a bunch of odd issues going on that I haven't seen anyone else have aside from problem 1. I've already tried turning iTunes Match off and on. I've deleted all songs twice. I haven't jailbroken my phone or anything. I can't find a pattern because it happens with matched, purchased, and uploaded songs. Sometimes it will happen to 1 song, I will try it again some other time on the same song. I listen to music for about 6 hours a day using WiFi and at least one of these problems happens about every 2 days.
Aside from the problems I've been having, the service is great. I do understand it's fairly new and even with all of that, I still think the positives outweigh the negatives, especially for just $25.
I'm lost, though. Anyone have any ideas?
Message was edited by: burakkuchi - Added problem 6.

When I went to restore my phone, I may have found the cause of these problems. I never deleted all of my original synced songs before enabling iTunes Match.
When I just went to do the restore, I figured I'd delete all of my songs, then disable iTunes Match. After deleting about 3.5 GB of music and disabling iTunes Match, I ran the sync to backup my iPhone. It said there was still 2.2 GB of music. I checked my phone just in case and there was 2.2 GB there, probably the original synced songs that I never removed.
Anyway, I'm doing the restore now just in case and will respond tomorrow with how everything is working.

Any reported issues with itunes 7 and Avast, McAfee, or Sygate?

1. Connect nano to computer (newest version of itunes, Dell XPS, XP latest service pack, Avast/McAfee/Sygate fo r security)
2. Do not disconnect stays on even after exiting itunes
3. Try to Safely Remove Hardware, error - in use by application
3. Do "My Computer" and the whole machine freezes while nano still won't show ok. Requires cold boot.
But... cold boot messes up sectors when using chkdsk, requiring a low level format. But then, wait for it... trying to update the nano would cause the system to hang again, causing another chkdsk error...
I finally figured out after two nights of banging my head against the wall that if I waited until the machine froze, then reset the nano, than I could get it out of there with the music intact before doing the cold boot. I was able to install itunes 7 on a work machine and get the nano restored, then connect it to the machine in question, get all the music on it, get the machine to hang, and reset the nano out of there....
This problem never happened in a year of using itunes 6, and it doesn't seem to be happening on the work machine (a Dell laptop). So, I suspect there is a conflict of some sort between itunes 7 and one of my three protection programs:
- Sygate Personal Firewall 5.6
- McAfee Personal Firewall Plus 7.1.113
- McAfee VirusScan 10.0.27
- McAfee Privacy Service 8.1
- Avast Home Edition 4.7

Problem with Macbook pro and Airport Express!!!

I'm having the same problem I have seen others with right now with my macbook pro and my airport express. I have set up and reconfigured the A.Express 3 times now. I have the green light, i have the Ethernet configured, I have full bars of reception but I cannot access the signal. meaning I can not go online even though everything is set up correctly and says that it's good to go. Anybody have any advice?
Is it an issue with having to re access the network I created with the Airport utility?
It worked the first time I configured the A. Express with my macbook pro no problem. Then suddenly my computer was just not getting internet. Even though all the settings were ok and I was even getting full bars reception from the device on my comp. So I reset the A.Express and have been having the problem mentioned above since that point. Please help me if you have any advice. Thanks so much in advance.

I had the same problem, and to test if I was connected launched Safari and Safari after a few seconds of not connecting, it shows you a dialog box, with options to follow up, I follow the dialog box and like magic I am connected to the Internet.

Time Capsule as iTunes HD and Airport Express connected to network

I purchased Time Capsule with the plan of making it my external HD for iTunes, wirelessly, not sure how to set that up.
Also I have Airport Express and would like to link it since TC does not have the connection outlets which allow the sound system to play wirelessly.
Thanks for the help.

Hello,

Can't forward ports with Cisco EPC3925 and Airport Express and Extreme!

Hello,
I have very big problem, I've been trying for whole day to forward ports for steam and I just can't I tried everything, I have Cisco EPC3925 ( Its main thing I think its router - right ? ) Then I have connected Airport Express to it with ethernet cable ( It's working as DHCP and NAT I have double nat issue in my airport program I don't know what is this ) also Airport Express is set to create a Wi-Fi network, then I have connected Airport Extreme with Wi-fi and set to exceed wi-fi network and can't change anything in it , can't open ports etc. etc. MY COMPUTER is connected to Airport Extreme ( 2nd device ) with cable ! So Im not connecting my computer to internet with wi-fi
Also I've been looking in Airport Express ( the 1st device ) and I saw that there I can open ports , but I opened them and nothing happend ... ports are still closed... Also I've set my computer ip to static , tried everything . And portforward.com site isn't helpfull . Also I tried to set Airport Express ( 1st device ) in bridge mode and nothing happend ( after I set it to bridge mode I can't open ports in airport program )
Please is there anyone that can Help me with this ????
Also I want to say that somehow I dont know how, but I managed to open ports in the past
I need to open all necessary ports because If I can't open them - I can't make a server and people can't join . I really really need help I've spent whole today's saturday to get it to work and this won't work !

Yes, the Cisco EPC3925 is a combination modem and wireless router or gateway device. This is the device that you would need to configure for port forwarding/mapping.
Then I have connected Airport Express to it with ethernet cable ( It's working as DHCP and NAT I have double nat issue in my airport program I don't know what is this )
A "Double NAT" condition is when you have two or more routers in series where they all have NAT enabled. NAT is a service that is intended to allow you to share one Public IP address with multiple Private network clients. This is what allows you to have more than one computer on your local network have the ability to share an Internet access.
Since you have your AirPort Express connected to the Cisco by Ethernet AND the Express is configured to have NAT enabled is why you are getting a Double NAT warning.
Normally you would want all downstream routers to be reconfigured as bridges (NAT & DHCP disabled).
also Airport Express is set to create a Wi-Fi network, then I have connected Airport Extreme with Wi-fi and set to exceed wi-fi network and can't change anything in it , can't open ports etc. etc.
You will need to reconfigure the Express as a bridge. The fact that you have configured the Extreme to extend its wireless range is fine.
Also I've been looking in Airport Express ( the 1st device ) and I saw that there I can open ports , but I opened them and nothing happend ... ports are still closed
You do not want to open ports on the Express. Again, if you reconfigure it as a bridge you won't need to as all of its ports will be opened.
Ok I understand what u said, so I set my airport Express 1st device in bridge mode - if I do that I can surf internet without problems etc. Then when I set it to bridge mode my computer gets adress 192.168.1.X ( My computer gets 13 and I've set it to be static ) so my computer is 192.168.1.13 then -> I open ports for example 2700-27015 ( for steam ) in my router cisco website witch is 192.168.1.1 and in ip adress label I put my computer adress 192.168.1.13 after I do this I reset the router and turn it back on after all this everything should work fine and my ports should be open right?? Well..I've tried it.. after this I can surf internet without problems of course but my ports are still closed ... Im checking them on http://www.canyouseeme.org/ and it says they are closed I've tried with pultiple ports such as 80 .. and it just won't work I don't know why..
Also someone told me to use DMZ on and in ip adress put WAN ip of my airport express ( if its NOT set in bridge mode ) and open ports for my airport ( also I tried to open for my computer too ) - It doesn't work
Please friend tell me you can help me ..
