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.

  • Try to use the Audio Driver ICHA97, boot Windows with Driver Signature enforcement disabled and install the Audio drivers from intel. – Steven Jul 30 '16 at 15:38
  • How to do that? I can change driver but i do not know how to do the other thing. – Dušan Jul 30 '16 at 15:41

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
  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)") onto your Windows 10 machine (run setup.exe)
  5. Reboot Windows 10
  • I don't see an ALSA audio driver in my settings, but I do have ICH AC97. Should CoreAudio work? Installing the AC'97 codec hasn't had any effect. – Merchako Dec 19 '18 at 22:35

    Here's the link without having to give RealTek your email... https://realtek-download.com/wp-content/uploads/2014/07/6305_vista_win7_pg537.zip – Wil Dec 28 '18 at 0:51
  • Worked for me. I found that for Skype, I had to further select the Microphone (Realtek AC '97 Audio) from a dropdown list-- originally, it was set to "Phone Line". – user1117791 Jul 26 at 20:12
