Crackling Noise During Music Playback after iOS 4.1 Update

So is there any info to the subject yet?

I plug my iPhone into my car every day, and the music on the radio is starting to annoy me..

They just HAVE to fix this soon!!

I think the combo with the iPod is 1 of the biggest reasons for people to buy an iPhone...
At least, for me it is..

Similar issue with my Pioneer DEH-P3100UB with my 32GB iPhone 3GS on OS 4.1. I plug the phone into the USB connection and receive "Error 19". I have tried different USB Cables, Phone Reset/Restore, turning off the deck and turning back on all to no avail.

Add me to the list

I've got a JVC Headunit

Add me to the list too.....Pioneer AVH 3100DVD iOS 4.1 Skips all the time

I contacted Pioneer and they told me the they where looking into it, but also told me that the problem exists on Apple's side of things.

ok so nothing back from iOS engineering on this yet. Most likely they are chewing on it. Talked to my friend (whom i talked with earlier) at apple engineering and they are looking into the issue, so that's promising! There's no clear answer of when a fix might happen but from reading in here, looks like the beta 4.2 fixes it. So that might need to just be waited for...

Add me to the list. I just upgraded my car stereo for the ability to (finally) listen to my songs and not the incessant chatter on the radio. Talk about frustrated. iPhone 4 and JVC Arsenal.

And another thing…
I note that when I have the iPhone plugged into the USB connector, the phone constantly drops and switches to the Bluetooth connection. I don't want Bluetooth because it has its own set of problems, as abundantly noted here, but it literally will switch by itself every 10-20 seconds, continually, to Bluetooth. Since I don't have Bluetooth selected but rather iPod on the audio source, I lose the sound until and unless I switch it to Bluetooth. It will not stay connected via USB and this is just maddening!
In addition, when I do listen via Bluetooth, as of yesterday, the FF/Rev buttons on the steering wheel no longer activate these functions on the iPhone (but they did as of 4.1 and until yesterday). What in the world is going on? Not happy with Apple just now. I love music, love the audio system in my TL and this has ruined it for me.

Yep. Throw me on the pile. Felt strongly enough about this to actually create an Apple discussions account to complain about it. Congrats, Apple. You've moved me to action.

•Running iphone 4 OS 4.1 through Apple's shipped USB - 30pin connector into a Pioneer DEH-P6200BT head unit.

•I get the tell-tale skips, studders and jerks during ipod music playback. Acts exactly the same way whether the head unit is controlling the iphone (accessory is connected message on the iphone's screen) or when the phone is in control via the ipod app.

•Tried to recreate the effect while playing sound-intensive games through the audio connection. Tested Plants vs Zombies, Epic Citadel and Angry Birds (the only games I had installed at the time). Skips and studders to NOT occur while these games are playing audio through the usb connection, only when playing music through the ipod app. In fact, I think the music skipping may actually stop while the ipod app is playing in the background during some of these games... which is kind of weird.

•Studdering is random. Never seems to happen at the same spot on the same song with any consistency.

•Putting the screen to sleep (tap the power button) usually triggers the skipping immediately. It doesn't do it as readily if the ipod app is open, but will do it eventually if left to its own devices.

•Suspected that it was an encoding error when I told iTunes to automatically convert to 128 AAC to save space. Playback of same songs on headphones and through iphone speakers does not trigger the studdering. Have no other 30-pin peripherals to test on. Anyone else notice the studders in any peripheral other then a car deck?

•Suspected that push-notifications, bluetooth, or other web-based apps might be causing issues in the background. Went to airplane mode and turned off all notifications. No effect.

•Tried resetting the pioneer deck's microprocessor. No Effect.

•Tried recycling iphone several times. No Effect.

As of this moment, I have not yet tried:

-restoring the iphone to factory settings
-reverting to the original mp3 files instead of the resampled 128k AAC files that itunes encoded
-running the iphone through the 1/8" stereo-input on the car deck (though I already know this will work fine, since listening through headphones does not cause a studder)

Has anyone else done these tests or other more elaborate ones that I can't fathom at this late hour? My goal, of course, is narrowing possible culprits so that Apple doesn't have to, and can therefore better spend their time making Keynote presentations to explain why these issues are everyone else's fault.

Tried restoring ipod to factory settings. Does nothing. Im pretty pi55ed off about this Apple better hurry up and fix this problem fast!

Add me to the list too. Only happened after iOS4.1 update.

iPhone 4 and Alpine iDA-X305.

Curiously, my friend has the same phone and software, but his doesn't induce the stuttering when he plugs it into my car dock. :o/

Must be software related somehow, but I'd like to see a fix soon please.

I have the Problems with the JVC JVC KD-R801 since 4.01 !
The communication between Iphone 3GS 4.01 is totaly buggy.
I hope that i don`t make a crash while i fix them every time
while i drive cause try of workarounds.
Apple you should see this ....
I come from germany where the law is not so extreme like in
america ..... it could hit your stocks when something like
that happen cause these errors all the time ....
I would fix this fast !
Realy angry about this bad work.
You have, i think, a realy big team around the iphone.
And then something like that.
Apple must allow the producers to use "Made for Iphone" and "Works with Iphone".
Apple test the units that they function well with their software.
And then Apple release a new OS version without testing these allready tested units, shame on you, sorry.
My Unit is released in Germany on 4.2010 !
Fix it fast, do it so.

that they

Hi

I just did an update to iOS 4.2 beta.

The problem has been fixed, so a solution is on the way.

I have the problems with my iPhone 3GS in my car using the USB/30 pin connection, as noted previously in this thread, but the Memorex iPod clock radio that uses the 30 pin connector does NOT have this issue.

On a side note, when the music cuts out entirely in my car (which is happening about every other song now, grrrr), there are two ways to get it playing again. I can either unplug/replug the 30 pin connector or toggle to another stereo source input and back to the iPod source.

This needs to be fixed yesterday. It is SO frustrating.

same issue here. Plays fine in other docking stations, skips in my truck stereo (Pioneer AVH-P4100DVD). Worked fine in my truck prior to upgrading. Also verified that another iPod, non 4.1, plays just fine in my truck. Hurry up with a fix........pretty please with a cherry on top 🙂

I noticed the same problems immediately after upgrading to ios 4.1.
I've always had the message pop up saying that "the device was not optimized etc" but never actually had any problems playing back music. How badly it "skips" varies but it's gotten to the point where I'm not using it in the car until they fix it...hopefully with the 4.2 update
