Microphone doesn't work after upgrade to 5.1

Re: Microphone doesn't work after upgrade to 5.1

I'm experiencing the same problem. Tried everything, microphone does not work with any guest OS on any version, on either Intel or AC97, on any paravirtualization interface. I tried it all. Also tried ALSA, Pulse and OSS.

Thought it could be a problem with pulseaudio, so I tried direct pulse and jack with pulse, no change. Tried Ubuntu Mate and Manjaro, no change.

I checked and there's a lot of changes in the changelogs for recent Virtualbox in the audio department. Apparently they broke audio input and probably have not noticed or been able to fix it.

Here's my logs, just for the record:

Hi All, suffering from the same issue,
a workaround for me -
- connect an USB headset, and connect to the it from USB devices.
- downgrade to 5.1.0 or prior.

is there any reply from virtualbox guys?

Just to add to the record, I do have the exact same issue.

I attached a clean log from a complete startup and shutdown of my machine.

I'm under Manjaro testing branch (the problem was also present on the stable branch) and running kernel 4.5.7 on a Lenovo Thinkpad E540.

So, there's a new VirtualBox version (5.1.4-110228) and the problem still persists. Probably we are not being heard (read) here in the forum by VBox people :x

Yes, it usually isn't read. They prefer the bugtracker. In your case, look at: Ticket #15802: [Regression] No microphone, Windows Guest, Linux Host. Make your voice (logs) heard there.
If you obfuscate any logs or other information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

I also have the problem, with Ubuntu 14.04LTS. Microphone worked well with virtualbox 5.0.xxx, but not with 5.1.xxx

I've uploaded a new test build which hopefully should fix the problem:

The files can be downloaded from the https://www.virtualbox.org/wiki/Testbuilds page.

Scroll down to the Latest test builds / 5.1.x builds section and download the build apppropriate for your host platform.

Could you please try this and provide the usual VBox log files afterwards then?

This test build is not intended for production use!

Thank you!

After applying the testbuild - same issue state,
My workaround for now is connecting an Audio USB dongle, connecting audio jacks to it and works.

@pentagonik: After installing it, and installing the guest additions the microphone signal is detected, but is heavily disrupted (stuttering-like). I have the same configuration as @albageddon.

EDIT: Downgrading to VirtualBox 5.1.0-r108711 solves the problem.

I just tried Virtualbox 5.1.6. Mic is working again. Yay! I have a Windows 10 guest. At first, mic input from host device was still going to CD Audio in the Windows 10 guest VM instead of the mic. I had to uninstall the HD Audio driver and let Windows 10 detect the audio card again. After reinstalling the driver, the host mic is now properly mapped to the guest mic.
