Hi all 

 

I’m currently running Unraid with i7700k 32gb of ram ive been trying to run the following dockers plus a windows 10 vm

 

Plex

Sabnzb

Sonar

Radar

UniFi controller

 

With the windows 10 vm I get a lot of latency and sound doesn’t stay In sync with the video would it be I don’t have enough cores of all that load? I’ve tried pinning the cores but it doesn’t seem to make a difference.

 

Would anybody beable to give me some advice?

Without any further info, out-of-sync sound sounds like (#badpun) it needs a msiutil tweak.

 

You might want to watch part 2 of SpaceInvaderOne's guide below. IIRC, it contains the instruction to use msiutil. Also recommend to watch part 1, which explains correct core pinning practice etc.

 

 

I never got sound to work in a correct manner, the way I fixed it was by passing through a USB PCI card. That way I got real direct USB ports for my VM & I just added a small usb sound card. Works great. As for the stuttering, where are you storing your vm disk? Make sure it's NOT on the array as parity could really damage your performence in windows

Have you tried msiutil?

Also IIRC, the Ryzen motherboard has 2 USB controllers built-in which can be passed through (with ACS Override, depending on mobo and BIOS) so you might want to try that - nothing wrong with USB PCI card but I feel it's too often given out as a "safe choice" when passing through the mobo USB controllers usually end up working fine. Save yourself a free slot for other things.

You are right, I actually just double checked and I too have 2 USB controllers on my motherboard, both in their own IOMMU group so technically I could use one of those. Might be something I can keep in mind if I ever rebuild my server, but since I use it daily I won't fix what isn't broken

 

Oh & Msiutil did help, but then I had a 3.5MM from my monitor going to my speakers, and if/when i turned my monitor off my speakers would give a loud "POP" when it disconnected, and a loud pop when it connected when I turned my screen on  ugh oh ! and I did notice...

"Audio device: Intel Corporation 9 Series Chipset Family HD Audio Controller" is also in its own group... I guess I could have used motherboard audio too?

Hey all

Just thought I’d give an update I managed to get the vm working perfectly I’ve pinned 2 cores to the vm and another 2 core to everything else I fixed thee sound issue by passing though the onboard sound I’m not really worried about the monitor sound as I use external speakers, but I will try and get the graphics card sound working the with msi interrupt tweak.

Just waiting for 2 pci USB cards to pass though USB port to have hot plug.

Done some latency testing and all good.

Thanks for all the advice!

I’ve got a seperate ssd for windows it’s not stored in array
