Noise during Airplay music playback

The noise I hear during iTunes 10.1 playback through AppleTV (2nd Gen) resembles static or old LP "pops" and it ranges from very occasional to almost constant. I've confirmed it happens on music from 256AAC selections purchased on the iTunes store or Apple Lossless or AIFF (lossless) cuts ripped from CDs but there may be other formats affected as well.

The Apple TV is hooked up via HDMI to a Pioneer VSX-1020-K receiver. My computers (happens on both) are either a Macbook Pro 2.33Ghz (circa 2007) running Snow Leopard or a Mac Pro early 2008 running Snow Leopard. I can either connect via ethernet or WiFi and the problem still exists. I can run the library and music files from an internal drive or an external drive and the problem still exists. I have an Apple Airport Extreme (2008) Wireless N router running the latest firmware (7.4.2). I have power cycled the router many times.

Any ideas?

The problem has gone away for me too! Just listened to music via the optical out to my Marantz and no popping noise. No idea what has changed, but I know there was no update to the AEs, Marantz or router. There could have been an update to iTunes or the Mac OS running iTunes as it seems there are always updates being downloaded (not as much as Windows, but still...).


Or could have been sunspots...

Consistently staticky, noisy, awful playback.


iTunes 11.2.2 playing a home shared library (also 11.2.2) over wifi

Air Playing to an ATV2.

DAC to a cheap old stereo receiver that has never popped, glitched, or ticked in all its nearly 20 yrs.


The only thing I've tried that resolves the issue is rebooting the AppleTV2. But it DOES resolve the issue.

Guys, i've been dealing with this issue for several years.

I'm currently using an iPad Air, and I AirPlay mirror the device to my PC using AirPlay receiver software called Reflector.

My PC is on wifi, connected at 200Mbit.

My iPad is also wifi (of course).

My router is dual-band.


I have drastically reduced the audio pops by changing the 2.4G and 5G channels on the router.

I live in a high-rise apartment, so I do have a LOT of neighbours that use both the 2.4G and 5G bands, I currently can detect 15 other wifi signals.

I used software which could determine the best channel for my router to use, and I don't get many audio pops anymore, but it hasn't completely gone.

If I switch to other channels, I could end up with audio/video lag/dropouts.


So some advise - experiment with different channels on the router, if possible run some software to find the least noisiest channel.


Maybe some of you solved your problem by accident, just because your neighbour changed channels on their router, and are no longer interfering with your wifi network!


PS - I notice that I get a LOT more pops during certain times of the day (mostly after 6pm), this is because some people leave their routers off during the day, and theirs doesn't auto-detect the best channel to operate on. So when you're having issues, re-scan your channels and find a better channel.

Hey, I thought I'd post my experience here. I was using AirPlay with an Airport Express (roughly 2013 model) and a Micromega MyDAC (a great, low-cost DAC, by the way), with both my iPhone and my Macbook Pro with Airfoil and got constant pops, no matter what I did with network settings, 5G or not, whatever.


So, finally, I just purchased a new AppleTV (MD199LL/A) and it works perfectly. No pops, no cracking sounds, it just works. Can use it to pump data into my DAC with the TV turned off.
