We would like to show you a description here but the site won’t allow us. PulseAudio is a sound system for POSIX OSes, meaning that it is a proxy for your sound applications. It allows you to do advanced operations on your sound data as it. I’m trying to get audio from an Ubuntu Server 18.04 guest to a Windows 10 host and PulseAudio doesn’t start. After I changed the files daemon.conf and defaulf.pa and I try to start PulseAudio I get the following error. Update: PulseEffects now also has an Ubuntu PPA (for Ubuntu 18.04 and 18.10). The PPA has a newer PulseAudio version (because PulseEffects recommends PulseAudio = 12) so keep this in mind before adding the PPA. Upgrading system packages may cause issues! If you can, I'd recommend using the Flatpak version of PulseEffects instead.
Although the pulseaudio snap is available from other channels (candidate, beta, edge), only the stable version should be used for production devices. The purpose of the other channels is for internal use for the development team of the pulseaudio snap. All necessary plugs and slots will be automatically connected within the installation process.
In this post, I compare several options of how to get the sound output from an KVM virtual machine guest, back into the host. I will compare spice server, pulse audio and a hardware solution.
The Host runs an Asus Xonar DGX 5.1 PCIE sound card.
In any case – harmonize sample rates of host and guest system
A common issue with sound passthrough between guest and host is lagging or chopped up sound playback. In order to fix this make sure the host and the guest use the same default playback sample rate.
Setting default sample rate in Linux
Mxq android tv box firmware download. open /etc/libvirt/qemu.conf via
sudo nano /etc/libvirt/qemu.conf
and uncomment the line Lg imei unlock code generator online free.
replace your username with example
open /etc/pulse/daemon.conf
and find/add/uncomment the lines and set these values:
afterwards restart the pulse audio service via
pulseaudio -k or reboot.

Set the frequency of your windows sound to 44100 Hz
Option 1 – use Spice Server
(+) Easy to set up(+) Very good for first setup of the VM OS.(-) Needs VM window open in order to work(-) a little more delay than direct pulse audio version(-) Adds an extra display to the VM.
This one is pretty straight forward, open the info page of the VM on virt-manager and add a spice server.
Adding the spice server adds actually several devices to the VM config, one for example is a display.
In order to hear sound, I have to open the VM while it is running (I hope the sentence make sense 🙂 ). Basically it is double clicking on the running VM in the virt-manager list.
Option 2 – use Pulse Audio
(+) Less sound delay than the spice server version(+) Less overhead once running(+) Nicer Integration(-) Complicated to get it working(-) Lots of users complain about bad sound quality
Pulse Audio with QEMU 4.2 (and above)
Edit the virtual machine config viavirsh edit <your vm name>
e.g. virsh edit windows10
Make sure the very first line of the file does read:
Instead of
Check at the bottom of your config if a line <qemu:commandline> exists. If yes make sure to add these options:
In case <qemu:commandline> is missing, find the line which ends with </devices>
and add the following block afterwards:
The 1000 in
represents your user-id, 1000 is the default (one user) Id.
Attention!
Make sure <devices> and <qemu:commandline> have the same indent.
Remark!
The <qemu:commandline> part can hold further options, simply append the sound options if others were already present.
Open the apparmor libvirt abstractions file via
sudo nano /etc/apparmor.d/abstractions/libvirt-qemu
Append the following lines
/etc/pulse/client.conf.d/ r,/etc/pulse/client.conf.d/* r,/run/user/1000/pulse/native rw,/home/your-username/.config/pulse/* r,/home/your-username/.config/pulse/cookie k,
Replace your-username with your username.
→ reboot your system.

Make sure no further audio devices are added by virt-manager – remove all audio devices from the virtual hardware details bar (left side in VM info view).
Troubleshooting
If you have no sound at all, run pax11publish and check if a server with name /run/user/1000/pulse/native is available.

The 1000 in /run/user/1000/pulse/native represents your user-id. 1000 is the default (one user) user id.
Attention!
After adding the enlightments, I had no internet on one Windows 10 guest (also not every time).
After some digging, I found a reddit post with the proposed “solution” to change the model type of the network bridge interface in the libvirt config from “virtio” to “virtio-net-pci”.
Remark!
Lorem Ipsum!
Settings in Virt-manager
As said before, add a sound “ich6” device to your VM.
Attention!
Do not use 6ch/9ch audio devices in Windows 10 1903 virtual machines. It creates awful stuttering and performance loss. Use ac97 audio devices instead.
Troubleshooting
If the sound distortions occur, make sure host and guest run at the same sample rate. You can also play around with QEMU_PA_SAMPLES and QEMU_AUDIO_TIMER_PERIOD values (see the reddit post(s) from the sources for further information).
Option 3 – use Hardware
(+) Very easy(-) Costs money
I haven’t tried this, but it should be easily possible to add a USB sound card to the guest and run the output back into your host sound card via a real audio wire (connecting guest line-out with host line-in).
