how you get Win 10 vm to not be choppy using it? or Audio being chopyy

[ghost82]

oh yes, sorry. Yes you have 3 usb controllers so you can try!

I will write how tomorrow.

In the meantime please confirm that you have unraid on a kingston usb drive and post your xml.

[comet424]

ya i use a 16gb kingston   i plan to go with usb adapter inside the case  have to go with different style  the ones i tried the case is too tight 

so its plugged into the phyiscaly ones in the back

 

for the vm

[ghost82]

You have 3 usb controllers, highlighted in these pictures:

 

2 of them are in the same iommu group (group 17): if you have already used acs override and it didn't split the group it's not convenient to pass it through.

Your mixer is attached to one of these 2 controllers.

Iommu group 25 contains the third controller and you attached to it the unraid usb drive.

 

The fastest modification to check if passing through the usb controller instead of the device (the mixer) is better or not is:

 

1. Shutdown the server

2. Detach your unraid usb drive and your mixer and connect the unraid usb drive to the usb port of the mixer, and the mixer to the usb port of unraid usb drive

3. Boot unraid

4. Put a check for vfio passthrough next to Group 25 (now it's greyed out because you have the unraid usb drive connected to it)

5. Go into your virtual machine settings, switch to advanced view and replace the whole xml with this:

6. Save the xml, start the vm and check

--------------------------------------

What I did to the xml:

. Deleted the single device passthrough (since the device will be attached to the usb controller which is passed through, you don't need to passthrough single devices, every device you will attach to that usb controller will be available for the vm), I deleted this block:

    <hostdev mode='subsystem' type='usb' managed='no'>
      <source>
        <vendor id='0x154e'/>
        <product id='0x5013'/>
        <address bus='1' device='3'/>
      </source>
      <alias name='hostdev0'/>
      <address type='usb' bus='0' port='2'/>
    </hostdev>

. Added the usb controller passthrough:

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x0a' slot='0x00' function='0x3'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
    </hostdev>

 

. Modified from pc-i440fx-3.1 to pc-i440fx-5.1: newer is usually better

 

------------------------

It should be possible to passthrough both usb controllers in iommu group 17, instead of the usb controller in group 25: since both are in the same group with the non-essential device it should be possible to passthrough all the devices in the same group. The pci-bridge, also in the same group should not affect a working passthrough.

But first, try with the above for a fast check.

ah ok ill give it a try.. i  was using the pci1440fx-5.1  but from that link you told me to read the one guy went to 3.1 to get things to work

 

ah so ill give what you said a try.. i swapped things i  tried every usb port  on the back except the the ones inside the  case  i didnt have e an adapter..

 

but i tried each port  for the mixer   did the deatach attach to get it to work in VM again

even playing MP3 or a Video  through RDP  but using the Windows Media Player was crapping out and it would stop the audio  and then the VM would actually reboot on me

 

whats causing that?   ill give those a try  tomorrow morning..   as i just got a chance to come on to check

 

so the group 25  why is it grayed out?  so if i switch the things its going to be checkable?  what a pain right?

[ghost82]

Because you have attached the unraid usb drive: unraid is the operating system of the host, if you passthrough that usb controller you will passing through automatically the unraid drive to the vm and the host cannot see anymore the unraid usb drive.

[comet424]

oh ok so thats a safetly switch for unraid  it disables it  so you cant bugger it up then right?

and why do some have no check boxes whats special about them?

 

ill try your settings in a bit  and will see what happens . i played with vm and drivers but never fixed the vm reboot .. also gonna try to my mixer with Volumio  VM see if it has the same issue then i can know if its Windows VM that is the problem

[comet424]

ok so i didnt get a chance  to try the xml  i got a usb hdmi usb hub thing.. as i wanted a usb HDMI..  but the unraid cant see the hub well kinda it doesnt see it in VMs to attach 

if i plugged it into my own windows machine i hear it attach but i dont see no hdmi  

 

but i dunno if the xml will work but i did swap location of the kingston and mc6000 mixer

 

the terminus hub thing is this device 

https://www.amazon.ca/gp/product/B08733BK1W/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

 

i wondering if unraid cant see usb c devices really i not sure..

but me swapping the usbs  did they go in the correct order?

 

i was hoping to plug this usb hdmi in   since the onboard hdmi doesnt work  since hte AMD 3600 or 3700x dont have on cpu hdmi

Unraid does see the device: it's in iommu group 23 (Terminus).

For this kind of device I think that usb controller passthrough is needed instead of passing through the device.

Note that you changed something! Now the acs override patch is applied and your iommu groups now are splitted! so my post above doesn't work anymore because iommu groups changed.

Wait for new instructions.

Let's try to passthrough the usb controller in iommu group 30.

 

1. Connect the mixer, connect the terminus, connect unraid usb drive

2. Check the iommu groups (screenshots you attached) : iommu group 30 must have attached terminus and the mixer; unraid usb drive must be in iommu group 22 or in iommu group 23

Note from the latest screenshots you attached:

Unraid is already connected to iommu group 22 (kingston datatraverler) --> OK

The mixer is already connected to iommu group 30 (DN-MC6000) + maybe the C media electronics usb audio device --> OK

 

Just connect the terminus in a usb port next (?) to the mixer and check that it's in iommu group 30 (now it's in iommu group 23)

 

3. Put a check for vfio passthrough for iommu group 30

4. Copy the xml I posted and replace that of your vm

5. Restart unraid and start the vm

i having problems...  

i checked boxed  30 and 23    and i guess unraid is in 22

 

i rebooted unraid..  and let it boot up.. i no longer have VMS,  dockers dont wanna show.  Fix common issues doesnt show any errors..  the System Devices Page  it shows the beginning the usb devices. CPU Threadings..   and just keeps doing the unraid progress thing for loading  

and sits there   VM page doesnt actually load anymore..  and this keeps doing it on multple reboots..  its stuck    cuz i checked the 2 boxes

 

and when you check a BOX    is it linking   or is it Breaking it up more to be in more groups

 

i couldnt understand that

 

cuz if i had   the 2 groups you mention to check.. and then i was doing video cards  2 Video cards 2 Video Card Audios

then that be say 6 groups linked together?    or wold that be 6 groups  seperated more

 

i still havent fully grasps it.. as i thought it wasnt to bind but more to split it up

 

 

but so far i can no longer use the system devices page or VMS   and i noticed  my 3500mb/s  nvme  so much slower  the bench test says 2200mb/s  

but if i copy in krusader  from the nvme to a different directory on the nvme i dont even get 2200mb/s  or 1500 figure half speed.. i actually get only 120mb/s  so i dunno whats going on.

 

i wish there was like a Tweaker program like windows has  runs and scans and says you should change this  turn this on turn that off

 

like Tweak IT  that was for windows in the past..

 

any way i can fix things? or just unplug all USBS and reboot 

as unraid isnt responding really..  like VMS  just stuck

what does it mean?

[comet424]

just means unraid was not responding...  vm page wasnt loading..   things taking along time to load in unraid on the dashboard..

had some weird error...  

i havent worked on vm  for a few days  as i didnt have time..  and i returned that termius  usb thing  i guess i need CPU with built on board video to get that type to work

 

and then i installed a usb manager from  another person  he said to install  as i wrote in the future features request..

@ghost82  so i ended up  rma  my nvme  as i having flaky issues   and then my Home assistant VM  broke spent all day  on that..  

but i tried my  usb sound card i use for Volumio   that i set to 24bit  44hz  to get out the crackly   as it runs as a VM

if i use the same soundcard   for windows 10 machine so i can use it to play to a projector..    it still stops and starts using VLC player  using a tv  and my usb as the audio  as you can see in the videos i posted..   i didnt do a video of the Mixer  as and the DJ software as i was just testing  the sound card..  i set all the MSI  util  when i ran it i check boxed them all..

but hopefully you can hear the audio cut out i used my cell....  video play back seems ok  just not the audio...

 

i also have problems trying to pass the Onboard Audio   you can check it for sound card in VM   but windows cant see it

 

if you do the onboard in the VM for Volumio  it actually wont boot up the VM  for some reason

 

but here is my Onedrive link

If you passed through the usb controller and you still have issues, I have no idea, sorry.

[comet424]

ah crap  i had to uncheck it because i was dealing with a different vm  and was having issues..  ill re try that enable the check marks

 

probably  amd x570 doesnt like windows 10vm  as it works ok  in Volumio  no poping you heard in that videos

 

maybe you can only pass pci sound card or a Video card hdmi audio and not a USB audio  i dunno  the tribulations of vms right lol
