Microphone does not work anymore starting with VirtualBox 6.

I got a Windows 10 64bit installation that works fine with VirtualBox 5.2.30 r130521 (Qt5.7.1) Audio configuration is PulseAudio with Audio Intel HD, both directions enabled. The host system is a Devuan Linux 4.19.0-0.bpo.5-amd64 #1 SMP Debian 4.19.37-5+deb10u2~bpo9+1 (2019-08-16) x86_64 GNU/Linux. I have tried installing 6.0.10 when it was released and today 6.10.12. After updating extension pack and guest additions, Everything works fine but the microphone which does not capture sound anymore. Since the VM is the only way I can use my clients' proprietary teleconferencing software (Skype for Business 2016) this completely defeats the purpose of the VM so I had to roll back the update. Twice now, first from 6.0.10, now from 6.0.12. Last version known to work is 5.2.30.

I am using a Jabra USB headphone, I do receive the audio output during a skype call through it, just the micro does not pick anything up with 6.0.10 or 6.0.12, but it works fine with 5.2.30

The problem solved itself after updating the host system kernel version to Debian 4.19.67-2~bpo9+1 (2019-09-10) x86_64 GNU/Linux, run the latest windows update and installing jabra headset software, which was not necessary before with virtualbox 5.2. So I am running 6.0.12 now and the microphone works. Had to disable 3D acceleration with the VBoxVGA driver, VBoxSVGA clobbered both skype and microsoft edge rendering, even after updating guest additions. So this ticket may be closed now.
