Crackling Noise During Music Playback after iOS 4.1 Update

+1

JVC KD-R801 over the 30 pins, over Bluetooth works fine

Add me to the list. Since upgrading to 4.1 my iPhone 3GS will skip when connected to my Alpine IDA-X305S.

Same here on iPhone 3Gs. This must be iOS 4.1 specific. Tried to switch phone to airplane mode because I suspect it is caused by the upgraded baseband to solve reception issues. No luck.

Why did Apple not test this? When will this be fixed? Any ideas?

Same problem with iPhone 3GS connected to a Pioneer VSX-920 AV Receiver.

Same exact problem--annoying clicking makes listening to the iPhone completely impossible over USB. Problem doesn't happen over bluetooth audio. This is with an iPhone 4 on iOS 4.1 and a 2011 Lexus ES-350, via an Apple USB-to-30 pin iPhone cable. Problem behavior started this morning, the first time I got in the car after updating.

2010 Lexus RX350 with Mark Levinson audio and 64GB iTouch... same issue. Snap, crackle, pop.

All started with 4.1... zero issues with any of the 4.0.x firmwares. Also have issues with the USB synch with the stereo occasionally i.e. the head unit will not recognize the iPod or I cannot FF or RW. All tied up in the same USB issue.

Wish I saw this thread before I started one over in the iPod Touch section ( http://discussions.apple.com/thread.jspa?threadID=2579607&tstart=0).

I'm having the same problem with my JVC KW-XR610 head unit and my 3G iPod Touch with iOS 4.1. Worked perfectly with 3.1.3, but now I get ridiculous crackling during playback.

Hope they fix this soon.

I have the exact same car (2010 Infiniti G37 with factory audio) and the exact same problem. Worked great until 4.1. Apple needs to undo whatever problem it created with this: seems like audio streaming through the dock connector is universally problematic.

In case it helps: I've noticed that if it gets so bad the sound stops playing entirely that I can turn off the audio on the car (by pushing in the volume knob) and then turn it back on and often it will right itself (until it happens again, of course).

Add me as well. I have a Pioneer DEH-P6200BT and am using an iPhone 4 with 4.1 and an Apple USB cable. No problems before 4.1. I had previously reported that I was able to fix the issue be simply re-connecting my sync cable...but unfortunately the fix was only temporary.

Same here. I have 2010 Acura MDX and no problems with iphone 4 with 4.0.2 but 4.1 is crackling like crazy. I tried a different USB cable and continued with same issue. Thought i was going crazy!

Yup, same here with my alpine deck, using the USB. I didn't have any problems previously. Now it "skips" every 3 mins or so.

Same here. 3GS, alpine x305
Plays fine over bluetooth but intermittent ~1 sec audio drops every couple of minutes when connected via USB.

Had a similar issue with audio dropping after the 4.02 update that was solved by resetting both the headunit and the ipod while it was plugged into the headunit. Also you could solve the former dropped audio issue by manually opening the ipod app, clicking on the bluetooth symbol in the bottom left and choosing "ipod dock connector" over bluetooth, suggesting to me that this is indeed a bluetooth v. cable conflict issue.

Haven't had a chance to try that with this problem yet. AAPL, please sort this out... it is getting tiresome to lose functionality of my "made for ipod" car stereo with each point or point-point update to the ios.

I have a Pioneer AVH-P...and as soon as i "upgraded" my audio drops out like every 20 sec r so of each song. I tried everything to go back to 4.02 but no luck. Now i am back to using my ipod classic since it was soooo annoying. I BOUGHT THE IPOD FOR MUSIC!!! The apps is cool and everything else is OK but the MUSIC is the most IMPORTANT thing for ipod. I bought the Pioneer for my ipod touch. PLEASE FIX IT or let us go back to the version that worked. I hope someone find a fix and post it lol.

Actually I have been noticing drop outs when playing music over bluetooth to my Motorola T500. I have never had issues before upgrading to 4.1. Weird thing is that it was way worse yesterday, only had a couple of stutters today. I'm on a 16GB 3G.

Hi Richard,

I am curious to know if this works. Cannot find a bluetooth button in the ipod app.

Thanks, Bart
