usb audio passtrough fail

All,

I have the following problems
I try to set up opensuse 13.1 with KVM/QEMU virtualization. The goal is to set up a multimedia environment which can control several usb audio devices. I want to achieve this with multiple virtual machines. So every guest OS has its own audio device. I have now W7 with virtualbox and several XP guests, this work perfect. Except its windows and I want a opensource solution.
So I choose KVM virtualization on the initial software configuration display. When I open Yast I can see the KVM/QEMU icons. I can create a virtual machine. I took opensuse 13.1 and added my USB headset. From the moment I add a audio (headset) usb device the installation freezes.
Strange thing is that I have a Linux Mint desktop with KVM installed by the repositories and with this installation I can create a virtual machine and add a usb headset (both logitech but a different type). The sound however is bad with a lot of stuttering.
The hardware I use for opensuse
Gigabyte GA-Z77X-D3H Intel Z77 (motherboard)
Intel Core i7 3770S 4x 3.10GHz
16GB Corsair Vengeance LP Black DDR3-1600 DIMM x 2
In the BIOS I have virtualization enabled vt-d

Kind regards,

Ignace

Hello,
You didn’t describe how you’re installing, managing and configuring your virtual machines although I <think> you are using libvirt (ie vm manager).

Did you try configuring a pass through device in the Guest properties?

TSU

Hey TSU
Thx for the reply.
For the creation of the guest I use virt-manager. It uses indeed the libvirt library.
In the add hardware option I add my usb headset. So I only use the GUI interface.

Let’s backup a bit and clarify.

What is
Your HostOS? (Operating system, version and if any Desktops)
Verify your GuestOS is openSUSE 13.1 (what Desktop, although may not be important for now)

When you said you deployed earlier on Win7, I want to make sure you’re either installed on different hardware or same hardware but <not> using Win7 as the HostOS. If for example you are running KVM within Virtualbox or something similar, many things won’t work.

TSU

TSU,

My host OS is opensuse 13.1.
In the software selection when doing the installation I selected KVM.
The guest I am trying to install on KVM is also opensuse 13.1 but this time as desktop selected.

I deployed the same setup before on the same machine BUT with W7 as host operating sys and virtualbox. XP as guest OS.
With this setup the audio passtrough went perfect.
The machine however crashed a month ago (after 2 years).

I hope this clarifies a bit the complete setup.

Kind regards,

Ignace

OK,
Now need to know the exact way you tried to configure your pass-through.

If you did it with command line, post the exact command you used.

If you did it using vm manager, describe the exact steps or post screenshots (if detailed enough, description might be enough)

openSUSE KVM - Is there, but is very general and I don’t usually use for unusual setups. Note says c2011

SUSE KVM - Although SUSE documentation ordinarily should be questionable for openSUSE, in this case is OK. Everything there including how to configure a number of pass through methods is described
