I have installed the Build 9926 of the windows 10 technical preview i.e The January Build, on Windows 7.

I am trying to use the voice assistance of cortana on my Virtuabox but am not able to do so. The microphone works perfectly fine on my host windows 7 machine

Any suggestions as to should i do so that my microphone works in virtualBox??

    It might be slightly off-topic, but it is the single most helpful resource on this topic (crackling audio, both in and out). Relevant link to track the source issue: Virtualbox ticket [#15925 (Crackling sound...)](https://www.virtualbox.org/ticket/15925) – ojdo Jan 16 '18 at 09:49

  1. In VirtualBox open the settings for your Windows 10 machine
  2. Go to Audio > Audio Controller, change to "ICH AC97"
  3. Boot your Windows 10 machine and disable driver signature enforcement
  4. Go to Realtek's website, download and install the AC'97 audio codec/driver for Vista/7 ("Vista/Win7 (32/64 bits) Driver only (ZIP file)") onto your Windows 10 machine (run setup.exe after unzipping)
  5. Reboot Windows 10 and you should be done

  • works like a charm. Both audio input and output works now. – train Feb 07 '15 at 16:44
  • Hmm I did get this to work, but didn't get audio input to work with this (but that's from a mac which may be related). As a side note, if you change your virtualbox audio setting to "Intel HD Audio" instead of "ICH AC97" then audio seems to start working without driver install required... – rogerdpack Nov 20 '15 at 17:29

    Beautiful... you saved me! – chrips Oct 01 '16 at 13:08
  • Thanks for this. Even though it's off topic, you saved me from having to reboot every time I want to skype. – Raydude Mar 29 '17 at 21:15

    Only works if you disable the Signed Driver Enforcement – Benedikt Köppel Jul 01 '17 at 11:19

    Didn't work for me :-( AC97 is just as bad as the default Intel HD Audio device. – cslotty Jul 13 '17 at 13:54
  • Realtek's link is dead now. – Andrejs Cainikovs Nov 26 '18 at 13:14

    @AndrejsCainikovs it works as of now. Although, it requires you give them e-mail to receive link. Also, the link will only work for 5 minutes. If you can't download it from Realtek website, try searching for `0001-6305_Vista_Win7_PG537.zip` - that's the archive containing the driver. – izogfif Dec 19 '18 at 06:07
  • I have used disposable e-mail to download their driver, but this turned out to be unnecessary - they did not ask to confirm it, so I guess anything can be typed in if it looks like e-mail address. – Lissanro Rayen Sep 27 '19 at 13:36
  • Works - you're a genius -- note: do not click setup.exe in the zip -- do a full proper extract and then run setup.exe. – jouell Nov 09 '20 at 03:07

    Not work for me with Windows 10 and latest VirtualBox 6.1. It had selected AC97 Audio, disabled code signing mode, downloaded and installed AC97 Audio Drive for Vista/Win7_64 and reboot the Windows 10 Host. Nothing worked for me :( – Hieu Nguyen Sep 27 '21 at 08:19
