Microphone stops working after resuming a virtual machine

[sbrunov]

Hello, Everyone!

It seems that a microphone stops working after resuming (from pause) a virtual machine.

It is worth noting that I am using the «ICH AC97» audio controller, because it is imposible to use the «Intel HD Audio» one (see the comment: https://www.virtualbox.org/ticket/14386#comment:81).

Any help would be greatly appreciated.

Scenario

Steps to reproduce:

1. Start a virtual machine.
2. Check the microphone. It should work properly.
3. Pause the virtual machine.
4. Wait for 5 seconds.
5. Resume the virtual machine.

Actual result: Microphone is working.

Expected result: Microphone is not working.

• CPU: 4 processors (of 8 processors in total), 80% execution cap.

Hello, Everyone!

Additional information

This piece of advice, https://www.virtualbox.org/ticket/14386#comment:82, has helped me enable the microphone the «Intel HD Audio» controller.

The defect is reproduced with the «Intel HD Audio» controller too.

Does the issue still persist with the latest version of VirtualBox?
