Zune 30 Audio Trouble

    My zune 30 sounds like the vocals are using an echo or reverb fx through ear buds - it is VERY annoying.  It sounds fine when the zune is hooked to my stereo (??!!). 

    I have tried all file types and bit rates has no effect.  

    I have tried 7 different ear pieces ranging from $9 - $100.

    I have loaded the new firmware twice.  

    I have reset the machine dozens if times. 

    I have tried various eq settings with the same results.

    The radio sounds GREAT with all earbuds (??!!).

    THe video sounds TERRIBLE - like the music.

    If it is insturmental it sounds good - that makes me think it is a DSP issue.  

    In all cases it sounds great through the stereo - that makes my think it is an output impedance issue (I find that hard to believe especially when the radio sounds fine.)

    OK - suggestions???

    I didn't solve it unfortunately, and I tried everything.

    Hard reset.

    Back the firmware up to 1.1.

    Nada.

    I'm glad it's not just all in between my ears!

    BTW, this problem poped up right after I went to Firmware 2.0.

    How do you go back to 1.4?  After I do a hard reset (to wipe it) the zune software pops up and installs 2.3.  I don't get a choice

    thanks

    It's rather technical, but here are the instructions. I was able to downgrade to 1.4, but it didn't fix my audio problem.

    And here is my original thread. No solution though. Anyone want to buy a crappy Zune?

    The weird thing is when I pipe the Zune output to the sound card's line-in, everything sounds perfectly. I think it may have something to do w/ the Zune's headphone detection do-hicky. An unnecessary point of failure, MS?

    How can it tell? It's an identical jack...

    And how much you selling it for? If I could get it to work I'd bet you'd be annoyed Tongue Out

    You say you have loaded the new firmware twice. So it has been upgraded to
    ver 2.3(1145)
    bootloader 1040
    Xldr 2.2.1040.0

    This is what my Zune shows, assuming this to be the latest upgrade.

    But you also say, "I have tried various eq settings with the same results"...
    But I have read that the Eq settings are not present after the upgarde for Zune 30 ( As new Zune , Zune ver2 does not come with EQ)

    Are you still getting Eq settings for your Zune 30 even after upgrade ?

    Yes. My Zune 30 firmware 2.2 (I'll check to see how it is on 2.3) still has EQ.

    Well, at this point, I just want something so I can b!tch & moan to MS about Smiley

    UPDATE:
    Zune firmware is now 2.3, and still sounds messed up. My Zune sounds horrible. (Google, go at it)

    UPDATE 2:
    I seems to have something to do w/ the format. I convert an MP3 to MONO, and Zune played it just fine (except for the missing stereo).

    So it would seems that the Zune can't play stereo MP3s. Buyers beware!

    I'm just asking you an eventually stupid question out of nowhere.
    Might it be, your Plug for your earphones is somehow not as well conducting as it should? Even if it's just one of the channels?

    Now, I don't think it's the earphones at all, because the FM radio works perfectly. So it's entirely the MP3 chips. I guess Zune just can't play MP3s.

    What bitrate and sample rate are your MP3's encoded at?  Maybe you've accidentally encoded them at some nonstandard bitrate or sample rate.

    I tried a few, it seems that stereo has something to do w/ it:

    256kbps, stereo, 44Khz -> BAD
    128kbps, stereo, 44Khz -> BAD
    128kbps, mono, 44Khz -> GOOD (except for the no stereo part).

    Maybe Zune just can't do stereo.

    I've had the exact same problem with my daughter's Zune 30; right down to "it's fine connected to a stereo [yes, even from the mini-plug]".  It is about 1 yr. old now and developed this problem about 3 months ago.

    After puzzling over this and examining the unit, I've found that the mini-plug jack on her unit appears to be just a bit out-of-round and not quite flush-mounted with the case.  The jack sits just a little counter-sunk toward the back of the unit.

    To this end, I plugged the earbuds in and started applying thumb pressure at the top of the molded plug housing, from the back forward, and VOILA!, I get full sound from the earbuds.

    All I can see in that direction (inside the jack, toward the back of the unit) is one contact, placed rather high for a mini-plug.  I would venture to guess that this has something to do with how they detect the difference between earbuds and, say, feeding a stereo input.  I'm not sure what the exact mechanism is (impedance matching, voltage feedback?) but as long as pressure is applied in that direction, the earbuds work fine.

    Until we can get back to the retailer, a rubber-band, while not too attractive (and much to my daughter's chagrin), has proven a very effective temporary fix.
