https://unix.stackexchange.com/questions/418708/spice-for-graphic-pulseaudio-for-sound
When we use Spice in a virtual machine under KVM/qemu/libvirt, the QEMU_AUDIO_DRV is set to spice by default. My host (debian-Stretch) use a good sound card (Xonar DX) and a better sound driver (pulseaudio,alsa). How to use in a virtual machine spice for the graphic aspect and pulseaudio or alsa for the sound aspect (whatever the guest OS) ?

Qemu audio. 参考一 参考二 参考三. 最近由于项目需要，研究了一下qemu audio。Guest调用Qemu的虚拟声卡设备，声音数据（PCM）传到Qemu后，Qemu再传给事先搭建好的后端接口，这些后端接口都是通过一些环境变量设置的，如果VM使用的是spice协议，默认会添加这个环境变量：QEMU_AUDIO_DRV=spice，音频数据通过spice ...

I have googled around, but I was unable to find a way to let spice to connect to pulse audio server. I could not even find how to set QEMU_AUDIO_DRV with virt-manager.

First you need to switch Qemu to use AC97, for the soundhw option use ac97 i.e. -soundhw ac97 and also set QEMU_AUDIO_DRV to alsa (I also am setting the QEMU_PA_SAMPLES to 128 and not sure if that will affect things or not) QEMU_PA_SAMPLES=128 QEMU_AUDIO_DRV=alsa

I use libvirt to control everything. My XML file is here. (I should mention, yes my uid is 1000.) My qemu.conf file is here. As you can see, I have nographics_allow_host_audio=1 included. I am here because I don't know what else to look at. In pavu there are absolutely no indications of any audio from the VM. My question is 2 fold.
