What I'm referring to is that passing through my integrated Audio controller causes issues, but when I pass through my USB Audio device I have no problems. It looks like you are not using hyper-thread pairs <cputune> <vcpupin vcpu='0' cpuset='1'/> <vcpupin vcpu='1' cpuset='2'/> <vcpupin vcpu='2' cpuset='3'/> </cputune> Check your thread pairs in settings system devices. your pairs will be 0 ------4 physical core 1 1 ------5 physical core 2 2 ------6 physical core 3 3 ------7 physical core 4 Only use pairs, do not use one hyperthread of a core or else you will get latency. So if you use 1 also use 5. If you assign 5 to something else that physical core 2 is split between 2 different processes and will be a performance hit. It has no relationship to the load on the cores so your max load being only 50% isnt an indictation your vcpu assignments are okay. I would try to pin emulator tasks to another core not used by the vm aswell. It helps alot of people get better performance. read dlandon's excellent post http://lime-technology.com/forum/index.php?topic=49051.msg470454#msg470454 Thanks for the assistance, but my CPU does not support hyper threading

Thanks. I did this. It has made somewhat of a difference but it's still not perfect. I have USB headset and the audio out of that is 100% perfect, so that's weird?

Having problems with Audio. I can't figure this out. I have everything in UnRAID working perfectly except Audio. When I play music and even system sounds I get random micro cuts in the audio, static noises and pops/clicks, along with the "underwater" sound but only for a micro second, it's never prolonged but is always noticeable. I don't think it's the MSI problem, becuase of this; it says MSI Enable-. lspci -vvv 00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31) Subsystem: ASRock Incorporation Sunrise Point-H HD Audio Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 32 Interrupt: pin A routed to IRQ 16 Region 0: Memory at df340000 (64-bit, non-prefetchable) [size=16K] Region 4: Memory at df320000 (64-bit, non-prefetchable) [size=64K] Capabilities: [50] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot+,D3cold+) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- Capabilities: [60] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Kernel driver in use: vfio-pci I have an i5-6600 with cores 1, 2 and 3 passed through to my Windows 10 VM, Core 0 is assigned to other VM's. I don't think it's a CPU problem. My Average CPU load never goes over 50% and when I run htop my system load is always ~1.7 or less. I've never seen it at 2. I have 48gb of RAM, and 16 of that is assigned to my VM. Here's my XML for my VM: <domain type='kvm' id='8'> <name>Nick-Desktop</name> <uuid>52e75470-0b77-15e5-24c6-a5a8d93e6823</uuid> <metadata> <vmtemplate xmlns="unraid" name="Windows 10" icon="windows.png" os="windows10"/> </metadata> <memory unit='KiB'>16777216</memory> <currentMemory unit='KiB'>16777216</currentMemory> <memoryBacking> <nosharepages/> <locked/> </memoryBacking> <vcpu placement='static'>3</vcpu> <cputune> <vcpupin vcpu='0' cpuset='1'/> <vcpupin vcpu='1' cpuset='2'/> <vcpupin vcpu='2' cpuset='3'/> </cputune> <resource> <partition>/machine</partition> </resource> <os> <type arch='x86_64' machine='pc-i440fx-2.5'>hvm</type> <loader readonly='yes' type='pflash'>/usr/share/qemu/ovmf-x64/OVMF_CODE-pure-efi.fd</loader> <nvram>/etc/libvirt/qemu/nvram/52e75470-0b77-15e5-24c6-a5a8d93e6823_VARS-pure-efi.fd</nvram> </os> <features> <acpi/> <apic/> </features> <cpu mode='host-passthrough'> <topology sockets='1' cores='3' threads='1'/> </cpu> <clock offset='localtime'> <timer name='rtc' tickpolicy='catchup'/> <timer name='pit' tickpolicy='delay'/> <timer name='hpet' present='no'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/local/sbin/qemu</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source file='/mnt/cache/FastVDisk/Windows 10/vdisk1.img'/> <backingStore/> <target dev='hdc' bus='virtio'/> <boot order='1'/> <alias name='virtio-disk2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/ISOs/Win10_1511_2_English_x64.iso'/> <backingStore/> <target dev='hda' bus='ide'/> <readonly/> <boot order='2'/> <alias name='ide0-0-0'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/ISOs/virtio-win-0.1.118-1.iso'/> <backingStore/> <target dev='hdb' bus='ide'/> <readonly/> <alias name='ide0-0-1'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <controller type='usb' index='0' model='nec-xhci'> <alias name='usb'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </controller> <controller type='pci' index='0' model='pci-root'> <alias name='pci.0'/> </controller> <controller type='ide' index='0'> <alias name='ide'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <alias name='virtio-serial0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </controller> <interface type='bridge'> <mac address='52:54:00:00:f9:b0'/> <source bridge='br0'/> <target dev='vnet1'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </interface> <serial type='pty'> <source path='/dev/pts/1'/> <target port='0'/> <alias name='serial0'/> </serial> <console type='pty' tty='/dev/pts/1'> <source path='/dev/pts/1'/> <target type='serial' port='0'/> <alias name='serial0'/> </console> <channel type='unix'> <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/domain-Nick-Desktop/org.qemu.guest_agent.0'/> <target type='virtio' name='org.qemu.guest_agent.0' state='disconnected'/> <alias name='channel0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </source> <alias name='hostdev0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x00' slot='0x1f' function='0x3'/> </source> <alias name='hostdev1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x00' slot='0x14' function='0x0'/> </source> <alias name='hostdev2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </hostdev> <memballoon model='virtio'> <alias name='balloon0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </memballoon> </devices> </domain> Any ideas on what I can do next? I've tried default windows drivers and the Realtek drivers, too. I've tried the audio quality fix in control panel (changing the sound quality to a different Bit Rate/kHZ too, to no avail. Any idea?

YOU JUST FIXED MY PROBLEM. I could kiss you. Thank you SO MUCH!!!!
