I've been unable to get sound input working on my windows 10 guest for some time now. I don't honestly know at what point the problem arose, as I rarely use this guest anyway, and even more rarely need sound input. Unfortunately, now I really need the sound to work as a new client uses a microsoft-only web-conference tool.
The symptoms (I should note that my host's sound works just fine) are one of several situations. In most configurations, when windows boots, there's a little red X over the loudspeaker icon in the tool-tray thingy. If I click on this, it launches some kind of diagnostic tool which ponders for a while, then says something on the lines of 'I've installed a new driver, reboot' but when I reboot, the whole thing is the same. For some configurations of VB, I can get sound output, but still no input.

4 Channel Low Profile PCI Sound Card with AC97 3D Audio Effects CMI8738 Works r76032: Driver is provided on the CD packaged with the sound card. I extracted drivers from the Setup.exe. This is a simple NSIS self-extracting installer. I decompressed it using 7z. I added installation files to my bootcd.iso for ReactOS. 1.15.6 Using Oracle VM VirtualBox With Oracle Cloud Infrastructure 1.15.7 Exporting an Appliance to Oracle Cloud Infrastructure 1.15.8 Importing an Instance from Oracle Cloud Infrastructure. RDP from the same windows machine to the VBox remote display - DOES NOT get sound installed a local sound card on the server and was able to have the windows 7 guest to play sound on it using ALSA interface, however, when using pulseaudio driver - no sound from the guest going to the local card (paplay did play sounds to the local sound card on. Open the Virtualbox main window and click on the vm's you want to check and take a look at the Audio section on the list on the right. If it says anything other than the audio system Mac uses, change it to that and run the vm to see if the sound is restored. For example, on one of my vm's it had been changed to null audio driver.

I've upgraded VirtualBox to the lastest version (as of today -- 5.1.22), and have upgraded several times over the life of this problem. Each time I have installed the corresponding guest additions. I have tried Intel, Soundblaster and HC-er,whatever hardware emulation, and also OSS, ALSA, and Pulse.

I can get *output* but only output using Pulse and the Intel hardware emulation. If I select ALSA and ... I forget which, but one of the hadware emulations, I get evil sound that's about half-speed, but also no input. With OSS, the boot process for the VM gets a VB message saying that no sound could be opened, and while windows thinks it's making sounds (volume controls show, that kind of thing) there's no output.

In the VM settings, audio shows as enabled, but of course there's no separation between input and output. When configured in Pulse/Intel mode, in the pulse volume control tool, it shows the VirtualBox / Windows 10 in the recording devices tab, and shows a moving VU meter (which is almost insulting, really! ) See the attached image.

Any suggestions? This seems really odd, and is certainly frustrating now that it actually matters to me!
TIA
