    Windows 8.1. [No Audio Output/Input Device Installed]


    Hi guys,

    i'm stressing out right here, i've been reading threads after threads about this problem and none of the solutions work on me, so i decided to create an acc here and post my thread, hope you guys can help me :/

    So i've just installed the Windows 8.1 PRO x64bit on my Asus N55SF laptop and when it finished setting up i noticed that i had no sound on my computer.

    After read threads here's the solutions that i've tryed:


    • Reinstall the Windows (Not Fixed) (3x)
    • Update sound drives from Realtek website (Not Fixed)
    • Update sound drives from Asustek website (Not Fixed)
    • Troubleshot the audio (Not Fixed)
    • Check for new hardware (Not Fixed)
    • Disable and Enable the High Definition Audio Controller (Not Fixed)
    • ​Refresh PC (Not Fixed)



    What can i do more? I really don't know, please help me here :/

    [Update] So, i was able to create the "Sound, video and game controller" on the Device Manager, by clicking on "actions" - "add legacy hardware" and with that i installed some bluetooth drivers that weren't installed, but, when i try to install the realtek high definition audio drivers it gives me an error "invalid access to memory location". I think that's because of the original problem (No device installed) but i don't know...

    Is the RealTek (on board audio) enabled in the BIOS? If its disabled it cause the problem.

    Were the Intel motherboard chipset drivers installed? This may cause the RealTek to not be detected, so the drivers can be installed.

    Hello, I found a solution. I had exactly the same problem and maybe this will help.
    The problem was, that I've installed Windows 10 via UEFI boot installation because of that, the hard drive partition was created as a GPT disk. That caused to the problem, that I couldn't find the sound device in the device manager.
    The solution is to install Windows via the normal boot menu (press [ESC] via ASUS screen).

    Hope that will help.

    It should (and does) work with UEFI/GPT. In your case, reinstalling Windows was the fix, not because the hard drive was formatted different.

    I have the exact same problem as the OP on my Asus N55SF dual boot system (Win 7 and 10) but only on Windows 10 (Windows 7 is fine if I run it independently, while it also has this bug if I run it through the Windows Boot Manager).

    I've tried everything in the past 24 hours, but nothing worked. I'm willing to test your solution, but I don't quite understand what I have to do. What do you mean by "install Windows via the normal boot menu (press [ESC] via ASUS screen)"? Could you be more specific? Thanks.

    If you have a UEFI BIOS then you can create a GPT formatted disc, rather than the usual MBR. However, as you had Windows 7 that, in most cases, means it is NOT a UEFI BIOS.

    As I noted, GPT is not the problem, the fact the user reinstalled Windows is the most likely fix for that user.

    Maybe it could give you a hint about the nature of this problem (which I don't have a clue about).

    Btw, I have a "UEFI boot" option in the Boot tab in my BIOS, so I guess it's a UEFI BIOS, but I just don't know for sure.

    Here is a step by step guide:

    This is the only thing that worked on my ASUS N55SF dual boot system: Win7 on HDD (MBR) and Win10 on SSD (GPT).

    Step 1
    Assuming that you have already Win7 installed on your primary disk, install Win10 on your secondary disk.

    Step 2
    When install is done, enter your BIOS and go to the Boot section. There you should see "Windows Boot Manager" as your default boot option. Change it so that your primary disk (where you have Win7 installed) becomes your default boot option (it should be something like "P0:" followed by your disk model number, mine is "P0: ST9750423AS"). Save and restart.

    Step 3
    Now Win7 should start automatically (no boot manager showing up). Enter Win7, open an elevated command prompt and run
    bcdboot X:\windows
    where X is the Win10 system partition as seen from Win7, typically E, F, G or H.

    Step 4
    Restart. You should now see the Windows Boot Manager (probably the Windows 10 GUI boot manager). Select Windows 10, install your audio drivers (if you already have, I suggest you uninstall them and restart before doing this), restart and you're done.
