My M-Audio AV40 are making my PC (specifically keyboard) act wierd. If anyone knows why...

I have a pair of m-audio av40 that I use with my PC. I have an issue where after I switch them on after turning on my PC. Sometimes not always, my keyboard will not be able to function. I turn my speakers on at times and everything is fine this is when i boot up my computer. There is the odd occasion though when I switch my PC on. Turn on my speakers and i recall the keyboard lights blink then it's completely inactive (cannot use). I think it's the power from when the speakers turn on goes back to my PC and shorts out the keyboard or something I can only guess. I don't think or hope I don't need to worry with my PC or keyboard stop working for good. Can anyone explain to me what's going on here though please. Thank you.
I had thought these speakers would be fine as PC speakers.

  • Hey Web Surfer,

    Thanks for posting!

    That is curious. I have never heard of this happening prior to your inquiry. The AV40 speakers do not connect to your computer via USB, so the speakers are not directly affecting USB power consumption. The only connection that you are making would be line level or TRS which would transfer audio from your computer or audio interface to the AV40s.

    It sounds like there could be something going on with the power. Do you have the computer and speakers (or any other devices) connected to the same power source?

  • Hi Nick. Thank you for the reply.

    It is rather annoying this issue as when it occurs I have to reset my PC so that the keyboard can then be used.

    That is right, it is via the Line port that the Speakers are connected to my PC and not by usb.

    My speakers are plugged into an extension lead where the PC power supply is also connected into the same extension lead.

    So just to some up a picture for myself mainly but hopefully may paint a clear picture. My speakers have 2 things coming out of it. The wire that connects into the green port (line) at the back of the PC. Then the power cable from the speaker that I have going into the extension lead. This same extension lead has my computers power supply attached to it also.

    My situation again - I would turn on my computer then turn on the speakers.
    Ideal scenario -> my keyboard doesn't appear to do anything out of the ordinary. I can then go about my business with my computer.
    Problematic scenario -> after turning my speakers on, my keyboards light would blink (the num lock light maybe caps lock, scroll lock light too I can't recall). A light from there would flicker. I then am unable to use my keyboard which leads me to resetting my PC so I can then use it normally. While resetting my computer I keep the speakers on (at low volume) so I don't experience the occurrence for a 2nd time. I can then use the computer but is annoying having to reset the computer to be able to use it.

    PS - would a different line cable help me perhaps. Is it the cable going into my Line that's causing this :/ . As you wrote in your last post, may have nothing to do with the Line cable. I would be grateful for any help with this as I have had this issue for sometime now. I'm trying to get to the bottom of it now.
    I called a shop I bought this from in the past trying to sort this out but can't really recall what was discussed. I think I was just asking about cables they had in the end. Unfortunately I don't think the store staff was as helpful as I would have liked. Hopefully this forum can help me.

    EDIT - Just spotted that you are an employee also by the tag next to your name. That's great to hear. I wasn't really aware of that info. Thanks again for responding to my post.

  • Do you notice that any other peripherals are affected like the mouse for instance? Is it just the keyboard that you experience this with?

    Can your computer's output also function as an input? It is possible that inputting an output could affect the computer if the port is not configured to receive an output.

    I do think it would be beneficial to test the AV40s and your computer with separate power sources to ensure that there is no short occurring from using the devices together. Have you tested the AV40s with another computer entirely? Does this cause any similar symptoms?

    Let me know!

  • It's just the keyboard that is affected. The mouse works fine.
    Thank you for replying with the suggestions you have posted also.
    Btw, i'm on I think a 7 day streak without the problem occurring so things are going well currently.
    My computer is a little old too so maybe if/when I buy my new computer things will be fine. Perhaps it's my old motherboard that is playing tricks. It was made in 2006 the motherboard.
    If I need to pursue this again I'll make another post here if that's fine. For now I think we can leave things as they are. Again, on a nice streak right now lol.
    If it flares up a little more than I might like this may lead me to investigate it once again but I can understand how this may be a peculiar case. As I recall you said you hadn't heard of anything like this before.

    I hope this thread remains open so I can post in again if need be. Otherwise I'll have to make another thread I guess.

    Must head off now. Thanks for answering though again. Hopefully I won't have to make another message regarding this matter ;). Bye for now.

    ps- I also got in touch with the company that made my motherboard and asked them if they heard of anything like this to that I'm experiencing. At the end of our conversation they had ended with saying. My motherboard doesn't support windows 10 and possibly it's a driver issue maybe. All speculative it was though I think. Anyway. Thanks again for your assistance.

  • I'm happy to hear everything is working well! I would say that the motherboard is a much more plausible candidate for causing an issue with your system than the AV40s - good to know that you contacted the manufacturer.

    If you start having any trouble with your AV40s let me know!

  • Thank you Nick. Can I ask.

    When I switch my speakers on there is no sound (the moment I turn the speakers on that is), I'll explain in a second.
    After I'm done using my PC for the day. I turn my speakers off before shutting down my computer. I turn the volume to the lowest also before turning them off on the dial of the speakers. When i turn the speakers off sometime there is a noise like a pop or alike.

    Should I be concerned by this at all? Ideally when I turn my speakers off like it occurs when I turn them on. There should be no noise I believe. Just a flick of the switch and good to go. The noise that occurs bothers me when turning them off sometimes, it's like a pop or alike.

    Thank you Nick.

  • It sounds like this is just the internal amp turning off - not something you should be concerned about. If you do start having trouble with the output of your AV40s or otherwise, please let me know and I will be happy to help you!

  • I’m thrilled
    [Solved] A bit late this reply but when i tried writing this in the past i had issue getting my login. So, i had a problem where when I turn on the speakers my keyboard would become inoperable. Basically, I have since reinstalled my operating system to my PC, Windows 10 OS. I think after this I had no issue at all.
    I've been switching on my speakers with my keyboard not showing any troubles whatsoever. Previously i upgraded to windows 10 from windows 7 but I think I clean reinstall of the OS was better for my PC. Rather than just an easy upgrade (a migration).I think other parts of my PC with how it ran was a little sluggish too after the OS upgrade. A clean reinstall of the new OS seems to have made my PC run a lot better. Also, eliminating this issue I had with the speakers-keyboard I believe. Thought i'd like M-Audio know anyway that this problem is no longer a problem for me :)
