Hi,
Now that i have a Windows 10 VM up and running with my GTX 970, i would like to passthrought my Creative Sound Card into the VM cuz it doesn't work well on Linux.
I have the Onboard Audio for Linux.
using the command lspci -nnk :

When I move a space on terminator on the host and the VM is running, it make white noise.
this is my vfio bind service :
[Unit]
Description=Binds devices to vfio-pci
After=syslog.target
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=-/usr/bin/vfio-bind 0000:01:00.0 0000:01:00.1 0000:04:01.0
[Install]
WantedBy=multi-user.targetthis my grub config :

GRUB_TIMEOUT=5

GRUB_CMDLINE_LINUX_DEFAULT="quiet pcie_acs_override=downstream intel_iommu=on pci-stub.ids=10de:13c2,10de:0fbb,1102:0005"
GRUB_CMDLINE_LINUX=""So my question is :
Do I need to passthrought ASMedia Technology Inc. ASM1083/1085 PCIe to PCI Bridge ? I tried it but nothin...
Can we Passthrought PCI Cards ?

I had distorted sound with HDMI audio from a 750 Ti. Enabling message signaled interrupts (MSI) fixed that.

Hi,
how do you start your VM?
In generally you don't need to passthrough your pci-bridges (vfio-pci isn't even capable to do so.)
I'm just using qemu-system to start my VM. To passthrough my NVIDIA GeForce GTX 660 (PCIe root port) and my Soundblaster Audigy ZS 2 (PCI) I use this:
-device ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1 \
-device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on \
-device vfio-pci,host=01:00.1,bus=root.1,addr=00.1 \
-device vfio-pci,host=04:00.0,bus=root.1,addr=00.2 \
-device vfio-pci,host=04:00.2,bus=root.1,addr=00.3 \please also provide
dmesg |grep -i vfioOffline
Have you checked if the sound card is the only card in your pci group?
You can check it via:
#!/bin/sh
# List the devices in each IOMMU group, from AW at
# https://bbs.archlinux.org/viewtopic.php?id=162768&p=29
BASE="/sys/kernel/iommu_groups"
for i in $(find $BASE -maxdepth 1 -mindepth 1 -type d); do
GROUP=$(basename $i)
echo "### Group $GROUP ###"
for j in $(find $i/devices -type l); do
DEV=$(basename $j)
echo -n " "
lspci -s $DEV
done
