    My speakers have a windy type sound to them, sometimes just cut out and give high pitch sounds.. Etc. Very annoying. Cut in and out. I have tried reinstalling my drivers, different configurations, moved the speakers around, the problem still persists.

    Hi SirHanz, many thanks for your reply.. I Tried to take a look and play with setting but seems that the feedbacks still there. So I did bough a new set of speakers Altec Lansing Vs 4121.

    I did pluged cables and did a test.. Same problem, hissing / feebdack in speakers. I read the User's Guide and it' look like the subwoofer is NOT magnetically shielded anso it must be kept at least 2 feet from pc ... So tonight I will move the subwoofer and see what happen, but I'm not sure that is my problem.

    Maybe I should say that I'm having Vista 64 bits version, with Asus P5K motherboard..

    Let me know if you need me to give more specs of my pc.

    Thanks a million for all your help, really appreciate !

    Ok, after trying by myself and returning to where I did bough my new pc here the status ...

    I'm still having that feedbacks/hissing in all speakers and headphones.

    The Tech, where I bough the pc, told me that he tried to change my motherboard to another Asus P5K and the problem was there again.

    He did also replace the power supply for another one but keeping the same brand / same power (Corsair 520 W.) again the problem was there.

    He did also a test with another video card, not sure if it was the same or a different brand, but in my pc I have a Ge Force 8800GT Special Edition overclock. Problem was again there....

    Finally the tech told me to put in my pc a sound card independent, I mean not in the motherboard look like that will solve my problem (as per the tech for sure)...

    But I'm questioning my self ... I'm really not sure if they really did the test with another Motherboard ... I doubt it...

    I really tried to find a setting to get rid of that sound and never solve my problem... And I have a friend who have EXACTLY the same pc as me , with the only difference ; he have a 485 W power supply and an Ge Force 8600 video car and he have NO feedbacks no hissing the sound is perfect...

    My question do you think it could be really a deffectiness of the motheboard ...

    Thanks a million for your help, this is really appreciate... I really need to fix that problem ...

You may want to try disabling/muting the microphone volume in the volume control. If it doesn't help please post back.

    O.K. giving that your testing a new set of speakers would leave me to believe that the problem lies within your computer. I highly doubt that having your sub too close would bring about the problems you are experiencing. I do however also recomend that you move the sub away from your computer as it may magnetically damage your hard drive. I have no expertise with Windows Vista, for I solely run Ubuntu 6.06 LTS on all of my computers. But seeing as most operating systems are generally configured the same, I reccomend you check the device manager for your sound card and check if there are any hardware conflicts there, if not please post back your Sound Card Identity. Also you may try updating your current driver for the sound card.

    It could very well be the motherboard, but if that were the issue trying it with another motherboard should have proved a result. Unless of course the tech you had never tried another board, it is VERY unlikely the problem lies with the power supply and/or video card. At this point if you have had no luck with an updated driver, I also would recomend another sound card, these are generally inexpensive and you may even be able to find a second hand soundcard from a camputer at a store they recycle computers at. I have a friend with an independent shop that will let me pick thru these computers for parts for free, so it is likely you can probably find a similar shop that may do the same for you. Generally any smaller shop will do this as to gain you as a customer. Again I am sorry to hear you are still having problems and please update us on any success or if the problem persists.

No sound from computer speakers

Make sure that you have the speaker plugged into the GREEN jack on the back of the computer or sound card. If they are not color coded then make sure it is plugged into the speaker out. Pink is for the mike and Blue is or plain is for input. You probably already know this but sometimes it helps to know if your not sure. Hope this is of some help. Bud

Logitech x530 hissing noise

I had the same problem for the longest time with my set of Logitech 540 5.1 speakers. Turns out the solution was pretty simple. All I did was open the Master Volume controller and mute the Microphone. Hissing went to zero. Sound is great now.

No sound


To my knowledge, a Logitech X-540 does not need a driver to operate. However, it is the sound card in the PC that would need drivers. Further, the sound card should be capable of 5.1 surround sound system and should have three (3) sound output which includes. All of these would have individual jacks to match the different plugs of the X-540 (green, black and orange plugs). The X-540 in turn would output the 3 inputs to front pair, rear pair, center and sub woofer. The green goes to the front L/R, the black to the rear L/R and the orange to the center/sub.

Perhaps you can post back with the brand/model of your PC , and your soundcard or motherboard. Knowing your OS would also be helpful.

Hope this be of help/idea. Pls post back as requested, how things turned up or should you need additional information.

Good luck and kind regards.
