    iPod Classic Firmware 1.1 WARNING



    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?

    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

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

    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. [​IMG]

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

    LOL. [​IMG]
    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.

    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. [​IMG]

    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?

    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.
