[size=large]iPod Classic Firmware 1.1 WARNING[/size]



Hi all

Just updated my iPod classic to the 1.1 firmware, and was experiencing a lot of weird noise in my mini^3 when the power in the iPod was off. Took it down to the workbench and did some investigating.

What I found was ~.5v of DC on the line out whenever the ipod is off. This could be really bad for your headphones if you are connected through a DC coupled amplifier (like my mini^3).

I also plugged it into my scope, and verified the .5v is usually just DC, but that occasionally (maybe 10% of the time) it's got some triangular pulses on it.

I'd suggest people stay away from the 1.1 update

That doesn't sound healthy... sounds like something you should report to Apple - is that possible?

 

[zumaro]

Ahh the explanation for what so many of us are experiencing - hiss and static noises after the iPod is turned off. Well done Apple - your quality control department must have been fired by now with crap update after crap update slipping through?

I've filed it as a bug through ADC, although it's a little bit different to the type of bug they are used to getting that way. We'll see what happens

So they actually have a bug reporting system! That's good, at least. I haven't used the original firmware in a long time, so I've never had to check. For all you 6G folks' sakes, I hope Apple will release a fix promptly.

My memory may be faulty about this, but isn't there a 1.3 firmware update for the classic? If so, does this have he asme problem?

No. 1.1 is the newest. I'm downloading it as we speak

 

[Barry]

Ah. I was thinking of 1.03. Hope Apple fixes the glitch!

 

[drummerboy47]

Great. I'm experiencing the noise too. Didn't notice it until updating to 1.1 from 1.0.3. I just sent Apple some feedback.

Does anybody know if this will drain the battery?

Will it damage my amp or my car setup if left connected?

Unimpressed.

Just be thankful they didn't charge you $20 bux for it, I guess.

LOL.

My brother has an ipod touch and he was like whatever, didn't care about the update. Guess it matters to those who need the apps in the first place.

I agree the quality control on ipods seems to be an issue everywhere I read.

 

[DJShadow]

Glad I'm not the only one who noticed this. The hiss is diabolical with e4's. I'll be even less impressed if the battery drains faster when turned off too.

 

[Sordel]

Yes, I've noticed it as well and am glad of the explanation. The hiss is not always there ... maybe the thing turns off after time, or perhaps it makes a difference how the iPod is turned off?

 

[serpico]

I would just exchange it for another just to make sure it's not the device. If you get the same problem with the new one, then it's probably a defect in the series. Maybe a flash model is better or just another brand.

Haven't had the problem until the new firmware update: I didn't make the connection until I saw this thread.
