    Stereo Audio Bleeding


    Hi,
    I have recently upgraded to Windows 10 from Windows 7. I'm having an issue with audio bleeding in stereo channels. If I pan audio 100% left I can hear it in the right channel at about 20% and vice versa, even though levels are showing 0% for that channel. I'm not using any special equipment, just headphones plugged into my PC. I'm using Realtek drivers.

    Things I've tried:

    • Installing latest drivers
    • Installing old drivers
    • Using basic Windows drivers
    • Disabling on-board audio and connecting a separate sound card
    • Disabling all audio enhancements
    • Clean install of Windows 10


    I've also tried plugging my headphones into a different PC running Windows 7 with no issue. I don't know what else to try to fix it. Hope someone can help. Thanks.

    Same problem as yours


    Hi there!
    I have the same problem and can't solve it.
    Did you solve this problem?
    Is it the same thing in windows 7?
    Thanks

    Sorry to say I still haven't solved it. My best guess is it's some sort of virtual surround. The problem only presented itself for me in Windows 10.

    Are you using "analog" headset or a USB headset? If its USB, that does not use the PC's sound card. If Analog (TRS connector) and you are using the front panel headset jack, try the rear GREEN speaker jack and see if the same problem.

    I have Realtek on Win 10 and not having that problem. I have a recording studio and "tuned" to audio issues. If it were there I would know about it.

    Thanks for the reply.

    I'm using standard 3.5mm analog headphones. They're plugged into the green jack in the back. I've tried multiple jacks, including the front panel and even a separate sound card. I'm sure it must be a rare bug as I've searched all over and can't find many people with the same issue, let alone a solution. I believe it to be a software problem rather than hardware since it only presented itself once I installed Windows 10. Unless for some reason Windows 10 doesn't like my motherboard. I might have to look into that.

    Out of curiosity. Is there any way you can test the HDMI Audio? That audio is generated by the video card, not the PC sound card.
    That will (or should) rule out the motherboard.

    Just finished testing HDMI audio. The problem is still there but very slight.

    That (sort of) goes back to either the motherboard or Win 10. Since Win 10 has been reinstalled, that leaves the motherboard.

    For testing, disconnect the front panel audio from the motherboard (connector should be marked HD Audio but may be the older AC97 audio). On most boards the audio connection is on the lower left of the motherboard. Then try the headset into the rear speaker jack.

    Disconnecting the front panel audio didn't seem to affect anything. I did, however, find out that I had a faulty headphone extension connected to the back panel that was amplifying the issue. I'm not sure how that was affecting the front panel. But the problem persists, just less so now that the extension is gone.

    One thing I missed asking, you do have speakers set for "stereo"?

    Do you have "computer speakers" connected or can be connected to the PC? and if you do, do these also have the bleedover?

    Another thought, if you have the Headphones connected (and Left/Right set to center) and run the speaker test, do you get any "bleedover" in the Left/Right?
