https://askubuntu.com/questions/719819/libvirt-configure-guest-to-share-host-audio
Following this bug report I understood that audio can be sent through the regular backends if the VNC client does not support it by changing the user and group the VM runs under to my current user and adding a VNC setting in the /etc/libvirt/qemu.conf like so: vnc_allow_host_audio = 1 user = "yourusernamehere" group = "yourusernamehere".

This is a known bug with KVM, and there are several bug reports and potential work arounds. Some people have reported using alternate sound drivers, the es1370 in particular.

# sound output is through regular audio backends. By default, libvirt will # disable all QEMU sound backends if using VNC, since they can cause # permissions issues. Enabling this option will make libvirtd honor the # QEMU_AUDIO_DRV environment variable when using VNC. # #vnc_allow_host_audio = 0 # SPICE is configured to listen on 127.0.0.1 by default.

ubuntu - kvm/qemu - Audio from windows guest to host ...
https://stackoverflow.com/questions/42320377/kvm-qemu-audio-from-windows-guest-to-host-without-spice
So, I changed the audio driver to ac97 (using the Windows Vista/7 drivers from Realtek), which solves the crackling a bit, but I still have frame drops, because I am using Spice. I have read online, there should be a way to get it working with ALSA and without a graphics console like Spice.

With libvirt listening qemu needs to be configured to allow connections to console. This part of things it's the qemu process running the guest rather than the overall libvirt daemon that's responsible. To enable the VNC side of things edit /etc/libvirt/qemu.conf: vnc_listen = "0.0.0.0" vnc_tls = 0 vnc_sasl = 1
