Microphone not detecting any sound: Windows guest, Linux host

Reported by: trifon Owned by:
Component: audio Version: VirtualBox 5.1.6
Keywords: microphone windows linux Cc:
Guest type: Windows Host type: Linux

Description

Host: Ubuntu 16.10 64-bit, 4.8.0-27-generic

Host audio controller: PulseAudio

Guest: Windows 7 32-bit

Guest audio controller: ICH 97 (Sound Blaster 16 not detected by guest, with Intel HD Audio guest does not detect any capturing device)

Microphone is correctly enumerated by the guest, but it never detects any sound from the host. On occasions the device shows as "unavailable" in the guest.

The logs show that the capture device is being correctly recognized.

Additional information:

  • Problem symptoms seem similar to the ones reported #15802, which is marked as closed.

  • Problem persists in virtualbox-5.1_5.1.8-111374~Ubuntu~yakkety_amd64.deb
  • It used to work correctly in the official package for Ubuntu 16.04: virtualbox-5.0.24-dfsg-0ubuntu1.16.04.1

To clarify: problem is also present with VirtualBox 5.1.8 r111374 with matching extension pack and guest additions as downloaded from the Downloads section of VirtualBox (https://www.virtualbox.org/wiki/Downloads), and not from Ubuntu's repositories. Attaching a log with VirtualBox 5.1.8 as well.

Another piece of information that could help: I am testing with a VM image provided by Microsoft for testing of IE and Edge. It can be downloaded from  this page. Specifically, I am using the "IE11 on Win7" image.

Same setup here, same problem. A downgrade is the only workaround I've found at this point (to 5.0.18).

I am seeing this same problem with 5.1.10, with an Ubuntu 16.04 host and a Windows 10 VM.
