Apparently I am one of the top hits on Google when searching for a cure concerning AirTunes suddenly dropping off the face of the earth.
In the spirit of possibly helping out others who have this same problem I thought I would write up a post of my experience and complement it with links to other sites that might be helpful.
The Problem
My problem seems to be similar to most, but my situation seems to be different. I currently live in a dorm situation, meaning there are a lot of people in a relatively close location. My Airport is sitting about 7 inches away from my laptop. I always have 5 bars of AirPort connectivity. My problem is that “at random” my AirPort suddenly stops playing music and disappears from my list of available speakers.
AirTunes stops playing and won’t start up again until one of two things happens, a) I unplug my AirPort and let it “reboot” or b) wait for an unknown period of time until AirPort decides that it has speakers again.
I decided to purchase Airfoil, from Rogue Amoeba, which did nothing to solve the problem, but it does allow me to have a small little window that constantly shows me the status of my AirTunes speakers. I have looked for a pattern, and I can’t find one. It happens at different times of the day, for different lengths, at different intervals, with different programs running, etc.
People at various forums tend to say that this is caused by different phones or microwaves that are on the same or similar channel and cause interference. I have a feeling that in my case it’s probably a combination of the two, and possibly something else as well, simply because there are so many people who could possibly be calling or microwaving at any given time. (Although one would think the large amount of concrete in between rooms would help dampen things…)
Possible Solutions
I think this is a situation where there is one symptom for many problems. One person claimed to have solved the problem by turning on “multiple speakers” in iTunes. This apparently worked for a handful of people, but the comments to the tip make it clear it won’t fix everyone’s problem. And there are several other soultions suggested in the comments as well.
Macfixit suggests that turning the network to a 802.11b instead of an 802.11b/g will solve the problem. I tried this a week or so ago, and it didn’t change a thing as far as I’m concerned.
MacNN has a thread about this as well, and while it doesn’t offer much for solutions, the members do mention a few things worth looking into when trying to diagnose the problem.
Apple’s site describes the problem in their knowledge base, but their solutions don’t help me. The ones I have tried didn’t work, and the ones I didn’t try… well, they didn’t help me either. (Several of their solutions don’t apply to me, and I am not dropping my router’s security. I just don’t want to do it.)
Apple’s discussion forums is full of posts about this. One posting claims the new 802.11n no longer has this problem
The best summary in the discussions is this post by Henry B.
Dropouts or cutouts in the music stream going through an Airport Express is among the most commonly posted problems here. Sometimes the problem simply cannot be solved.
For everyone having the problem, there is a new set of variables. Even using XP and a brand new laptop, give a problem when a 5 year old laptop didn’t.
Conclusion
The more I look into this, the more I think it’s impossible to find one permanent solution. The general thinking is that this is an internal bug cause by some code, or some setting that isn’t quite right. In some cases, I think this may be true. Overall though, I think the problem comes from external sources. If someone in your neighborhood gets a new phone, it might interfere with your network. Not knowing everything your neighbor is doing a few houses away, it’s easy to attribute the problem to that new security update you downloaded a few days ago.
There’s no way of being aware of what all is going on around you and it’s sometimes hard to keep track of what’s going on in your machine. Many of us are probably experiencing several different problems that all result in one thing: AirTunes cutting out or dropping off.
My Current Setup
I can’t help but add in this little anecdote here at the end. It’s impractical for most people, but it’s my current solution.
I usually have iTunes running and playing music, but with iTunes and Airfoil running and playing music, my processing power is usually at 50% percent with just those two applications alone. Adding in, say, Photoshop or iMovie or another heavy program causes a huge slowdown in my system. I finally had enough, and decided to move the majority of my songs to my Windows XP box that I don’t usually use anyway. I then hooked my stereo directly to the computer and hit play. No more going through AirPort and thus, no more drop outs.
