7.5.2 Update causing skipping when playing via AirPlay

may i ask how you change the channel? mine's set to automatic, and channel 7. in the summary screen, i click the little arrow to the left and it takes me to the WPA page, but i dont see any way of changing the channel on any screen. help!

thanks,

dav

Dav-

I am with you.... same thing... how do you change the channels??? Thanks.

i dont know! nobody responded and told me how! i'll try to figure it out and report back if success. please do the same.

I went back and switched my firmware to 7.4.... solved my problem (at least my airport expresses played for 2 hours without interuption). I'll try the chanel change if I can figure out how to do it and if problem reoccurs.

BTW. I have 5 AE's. Two are extending my network (I live on 1 acre). Three are for airplay. Those three I rolled back to 7.4 and airplay seems to be fine now. The extenders I left at 7.5.

Scratch that.... today doing the same thing from iphone (even though switched back to 7.4). No problems playing from Mac. Can someone elaborate on how to change channels???

Dav.... found it.... change the setting off your main airport extreme under manual mode... not the airport express it self!

Still need help with changing channels. After I change the channels of 2.4ghz (in my case changed to channel 10), two of my five airport expresses still default to channel 149 on 5ghz. I have tried reseting them and they still like 5ghz for some reason. Any advice???? Thanks.

Hi all I am having the same oproblems but it seems to be random and happens about 4 to 5 times an hour, where can I get the older firmware version and is it easy to do.

Thanks.

Just to throw my two cents in, but I am having the same problem -- AX units will periodically go quiet and then after a few moments resume streaming music.

I'm running 5 AX units. Three are connected via ethernet on a gigabit network. One of the ethernet units creates an "N" network that the the 4th AX connects to (and which nothing else connects to) while the 5th AX connects to the house's general use G network (it's a big house and a big network). But other than music most of the network traffic is wired. Most connect to stereos with analog cables, but one of the wireless units has a TOSLINK connection to the stereo.

All are the newer N series AX units with 7.5.2 firmware, and itunes is 10.2.2.14 running on a Vista PC.

Miscellaneous laptops, ipads, itouch. Both of the latter use the Remote utility. A couple of gigabit network switches.

The PC with itunes on it is connected via ethernet. All music is stored on a home server, connected via the gigabit LAN, running Ubuntu 10.04 with Samba and fast eSata drives.

I see that some have had success dowgrading the AX firmware, and I may have to try that. The Airport utility was upgraded to 5.5.2 before the AX devices were upgraded to 7.5.2. At my GF's house all her music is stored on her laptop and she has the same problem, so I'm pretty confident it's not a server issue.

To try and narrow the problem down I am going to try:

1. Airfoil instead of itunes (although I'll have to figure out how to play my itunes library)
2. Using only the wired devices to see if its the wireless that is causing the problem
3. If step 2 solves the problem then sequentially add the wireless devices back on -- I'm wondering if one flaky AX unit could cause a sync problem for the whole AX network and cause the skip? I wish there were a diagnostic routine for the AX units -- how does apple maintain sync across these devices?

I'll report back once I know more, but it is annoying.

Hello,

Having some of the same problems you have experienced with two airport express devices. How did you revert back to 7.4.2? Thanks in advance...

I'm having a related problem. As a classical music lover, this is driving me nuts. It's especially noticable in soft passages in the music, when the volume is turned up high. When the dynamics increase, little pops/clicks appear (they sound a bit like static noise). It happens at irregular intervals. When you play pop music, the clicks will disappear (drown) in the music. But for true audiophiles who listen mainly to jazz and classical music this is a severe problem.

I have checked everything and it's definitely an airplay issue. My apple lossless files are 100% okay and play without any problem, except when streamed via airplay. Also, it makes no difference whether you use the analogue or the optical ouptut from the airport express.

I've created a sine frequency sweep myself in Adobe Audition, from 20 Hz up to 20000 Hz with a duration of 25 seconds and a level of -6 dB.

When played through airplay, the clicks always start to appear after 4 seconds in the sweep, only to disappear at 23 seconds.

The clicks manifest themselves at different volume levels. To my ears, they make the same sound as when you change the volume in iTunes when streaming music through airplay. Only when you set the volume in iTunes extremely low, the clicks will disappear.

Apple engineers should use a frequency sweep to recreate the problem, as this is very revealing.

PS: file format isn't an issue here. I've converted the Apple Lossless file to MP3, and it makes no difference at all.
