Altec Lansing M604- Zune Sound Corrupted

So I just got my Altec Lansing M604 for my birthday, and it worked fine the first day, the sound quality was perfect, and I was giddy with anticipation for the many songs I'd play. I went out for a weekend and left it plugged into the electrical outlet (oops?). The next time I (correctly -I checked) inserted my Zune, and turned it on, it started doing this sort of clicking and thumping that could be associated with the bass, so I unplugged everything, did all the steps by the book to set it up, but the clicking/thumping continued. My music would play through it, but the interference every half second was understandably too much. I unplugged it, and became very frustrated. leaving it unplugged, I looked at the troubleshooting section of my manuel, but it was no help. I left it unplugged for about 15 minutes, and when I plugged it back in, the sound was fine. Thinking I just overheated it, I let it play, but there was not 5 minutes of music before the noise persisted. I've tried to correct it many times, moving the stereo to different places in the house, and even trying a different mp3 player, but nothing's helped. Please help.

    Yes- I have the same problem. A thump-thump-thump from the speakers, sometimes only after a few minutes of play. Resetting, or cycling the power doesnt make any difference.

    I have exactly the same problem

  • op4h Dec 24, 2007

    Got it as a gift last month and now makes a popping sound when its been plugged in for over 15 minutes. Once it starts, it continues even without the Zune attached. It was great when it worked, but now it just troublesome. Does anyone know if Altec Lansing replaces these defective units? I've left a voice message with Altec Lansing support, but I sure I won't get a response until after the Christmas season.
    ps. Merry Christmas to all!

    I have the same problem...after 10 minutes or so the speakers start making a popping sound. I tried unplugging and reconnecting each cord with no success. Help?

  • all4johnsons May 08, 2008

    I have the same problem and have tried the exact same steps that you are describing. If anyone knows of a solution, please direct me to it.

    I also have the same problem with my M602 for the Ipod. It worked for about a coupe of months and then once the clicking/popping sound started it would not stop even with the Ipod removed. I have searched the internet for a solution with no answers.

    I have the same problem. I bought my unit on March 25, 2009 and it started within only one week of owning the thing. I'm talking to Altec Lansing support now to see what they are willing to do. So far they've decided to offer me a iM414 speaker dock to replace it, but it doesn't have any of the options of the M604 nor does it have the sound quality.

Try rolling back soundcard drivers. I had the same problem when Win XP updated my soundcard drivers.

It sounds like the subwoofer speaker has blown. If you are comfortable working with a soldering iron and speakers then you can open the case and replace the speaker with a replacement subwoofer speaker. A good online store for replacement speakers is

Altec lansing imt620 no sound, everything else works fine (speakers are ok)

Pardon my question; but what do you mean everything works fine? Have you attempted to attach the speaker system to an other device, such as a Receiver, DVD player, TV, etc? First check and see if the System works on other electronics and if it is working, then you go back to your computer and start from there; and I assume "everything works fine" could be the computer. The Altec is one of the best systems out there and their quality superior. It is rare to get a new Altec in a defective state as they do a great job on quality control.

No sound out of my Altec Lansing ADA 745. Computer Sound card is fine.

If other speakers are working, then 745 is defective or the volume switch is set to mute. Please check that, repair it if required.

M602 Speaker Problem,.. Popping Sound

This worked for me on my M604: Try inserting/removing a headphone plug into the jack several times to see if that clears the problem.

The "popping" sound is very similar to the sound that the unit makes when inserting headphones into the 'headphone' jack on the back of the unit.

The jack has a contact switch that triggers a relay inside the unit. If that contact switch is 'on the verge' of making contact, slight temperature changes may cause deform closer to it's contact target. The subsequent capacitance build-up and discharge across the gap could explain the cycle of popping noises after the unit warms up.

Was given ALtec Lansing Speakers for a birthday gift -- VS2420. Can not get the drivers installed without buying something online as far as a driver update -- this is nuts. Please help me install....

You do not need any driver for your speakers.If your PC gives sound through headphones then connect the speakers to the same port of PC to make them work.

hello FrankH2,

time to change your remote. You also get one from Altec Lansing, but you have to RMS if you register your product, or go on and check the way to change your remote. Other than this, is go to repair shop near you , and see if the Tech personel, can check the remote, for fried line or capacitor.
