The CPU isolation and interrupt reduction for the guest CPUs seems to
have greatly reduced the audio problems.
Thanks for that.

What CPU are you using?

What you suggest is something that previously happened to me in Xen around two
years ago. Xen 4.3 worked fine with PCI and VGA Passthrough, but when 4.4 was
released, they somehow wrecked it. The Passthroughed Sound Card audio was
horrendous, and the Video Card was a no-go - good thing is

Yes, this keeps coming up now and again on this list.
My solution was:
1. Buy a dedicated PCIE sound card
2. Pass it through to the guest
3. Route audio: mobo soundcard > guest soundcard
In essence, the always-on guest would handle audio, but I would still have
crackles (rarely), especially from

For me, letting the host load the driver (snd_hda_intel) before passing
through the onboard audio to the VM fixed the crackling and buffer
underruns. I never found out why this worked...
Passing through the physical USB 2.0 controller worked wonders for my

Hello everyone,
I am running a fresh Ubuntu 16.04 and want to use kvm/qemu to run a
windows VM with a gpu passthrough, however after patching the kernel
both gpus are still within the same iommu group 1.
My system:
- Intel Core i7 6700
- Gigabyte GA-Z170X-UD5 TH Intel Z170
- 1x GeForce GTX 650
I have a on motherboard audio card that I can pass through to a vm without
issues.
If I do the same with a usb audio device I also get the crackling on playback.
So I suspect it is due to the latency in the emulated usb.
Possible Solutions:
- Pass through a pci audio device. (on motherboard /
Check your DPC latency, it is one of causes for cracking sound. This is
exact reason i stopped using vga passthrough for gaming..

I actually have this problem with passed through audio. I could improve
there situation by fiddling with the sample frequency and size in the audio
settings. Currently running at 192000Hz and 24 bit.
My first instinct was to blame it on me skimping on the CPU, because I got
me a quad core i5 instea
I am not the only one who has this issue, but if you emulate an audio card
you end up with occasional crackling audio output, which is sometimes
associated with drops in FPS.
I know there are ways to pass audio devices to the VM directly, but in many
setups it would be preferable to pass the audio
