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. |
