I installed Windows 10 in virtualbox on my macbook and now speakers and mic are not working with win 10. My problem is mainly with speakers.

had a similar problem (audio cracking/not working); what worked for me (Xubuntu as Host, VirtualBox 5.2.14) I found on stackoverflow marked off-topic:

  1. VirtualBox - open the settings for your Windows 10 machine
  2. Go to Audio > Audio Controller, change to 'ALSA Audio Driver' and "ICH AC97" as Controller
  3. Boot your Windows 10 machine and disable driver signature enforcement
    1. open command prompt as administrator
    2. execute bcdedit /set testsigning on
    3. reboot! (yes, it is needed)
  4. Go to Realtek website, download and install the AC'97 audio codec/driver for Vista/7 ("Vista/Win7 (32/64 bits) Driver only (ZIP file)" archived 2017) onto your Windows 10 machine (run setup.exe)
  5. Reboot Windows 10 (optionally run the previous command with off instead after installing the driver.)

If you are having cracking sounds, this have nothing to do with the driver. You will have to research about real time audio tweaks in windows. It is a completely different subject. Usually running in "exclusive mode" (it should be an option in your application settings) helps.

Combination that worked for me (Ubuntu Host, Win10 guest) :
In Win10

  • install realtek driver In virtualbox
  • Host audio driver : PulseAudio
  • Audio Controller: Intel HD Audio

I got it to work by:

  1. Follow the answer by definitely undefinable
  2. Before rebooting, opening the windows device manager (Win + R, enter devmgmt.msc and press Enter)
  3. Find the Multimedia Audio Controller in one of the categories. It should be displayed as missing a driver (yellow exclamation mark in the icon)
  4. Right-click on the listing and select Update Driver Software...
  5. Select Browse my computer for driver software
  6. Browse to the unzipped Realtek driver folder. Make sure Include Subfolders is checked. Press Next.
  7. Select Install this driver software anyway.
  8. Reboot the VM.

I furthermore had to change the Virtualbox settings back to PulseAudio, as I am using this on my Ubuntu 18.04 setup.
