Trouble updating BIOS to fix in-built microphone not working on Swift SF514-51

Hi there, the in-built microphone on my Swift SF514-51 has stopped working for a while. I uninstalled and reinstalled the drivers to no avail. I came to suspect that the problem was due to a Windows update (as mentioned here) so proceeded to download the BIOS update provided by Acer [BIOS_Acer_1.07_A_A - Updates DMIC (Digital Microphone) settings and enables WoV (Wake on Voice)]. However, when I attempt to install it, I receive the following message:

Is there any way to get around this? Or any alternate fix to the microphone issue? Please kindly note that I haven't tinkered around with BIOS settings before. Thanks very much in advance for your time!

    As it says, you are running 1.13, which includes all the fixes that were in the earlier 1.07 BIOS.

    Thanks. The microphone is still not working though, so is the problem something else?

    Most likely. You said you've already redone the drivers, so I assume the mic is showing up in Device Manager. Does DM have any warnings showing? Like for a USB port or hub? The mic is internally just connected to a USB port, so if that hub isn't working right the mic would also not work.

    Device Manager for Microphone shows this under Properties > Events

    Device Not Migrated
    Device SWD\MMDEVAPI\{0.0.1.00000000}.{ec73ffd3-1759-470e-a006-8da6411af0d3} was not migrated due to partial or ambiguous match.

    Any idea what that could be?

    You tried to put a SF514-52T BIOS on your SF514-51 laptop. You are lucky that you didn't bricked your laptop.

    OK, that's a message saying Windows had issues with an update for the sound.Try this: Remove the sound drivers then do an update drive but instead of letting it happen automatically select:
    1. Browse my computer for drivers
    2. Pick from installed drivers the "High Definition Audio Device".
    Let us know whether that helps.

    Hi there, I tried doing this as you described but it's still not working. Any idea what the problem could be?
    (And sorry for the bump!)

  • Have you checked the sensitivity and volume of the microphone in the sound properties?

    Yes, I have. Adjusting those settings makes no difference, unfortunately.

  • can you check if the same problem occurs when reinstalling windows 10, pressing alt + f10 before the acer logo?

    Did you mean I should reinstall windows 10 and then press alt + F10 before the Acer logo?

    When you do the Alt-F10 process at boot-up it uses d2d to reimage the machine back to factory defaults, rather than back to Windows defaults.

    Hi, I tried resetting the system with Alt+F10, but the mic is still not working. Any idea what the problem could be instead?
  • When you plug in the headset, does something appear in the notifications?

    Just to clarify, this is about the in-built mic of the laptop itself. There are no specific notifications when I plug in a headset.

    What he was trying to determine was if it's a problem with the builtin mic, or any mic. If external mics work fine then the issue isn't likely to be a driver problem and more likely to be hardware.
