+Audio: missing ability to disable microphone input from host?
+Description of problem:
+**It appears there is no way to disable the microphone / input to the audio backend device(s).**
+
+
+There are at least two cases where this matters:
+1. The host has no microphone input (e.g. only HDMI audio output with video).
+2. The host has a microphone input, but the user doesn't want the guest VM to have access to the microphone/input.
+
+I tried the option in.channels=0, as that seemed the most obvious way, though that doesn't work.
+
+For -audio dsound, it appears that CLSID_DirectSoundCapture is unconditionally acquired.
+
+There will also be later periodic warning/text outputs from QEMU "Could not create a backend for voice virtio.in", if you're running on a host system with no audio input device.
+
+Adding a couple backend checks for channels > 0 may work well.  Not sure if it matters that audio front end device in the VM still thinks there is an audio input.
