vMix 26.0.0.45 x64

Our vMix install seems to be crashing several times a day at various intervals.

I'm not sure what I need to provide here for help, so please let me know what else I can provide.

I have been into Windows 11 Event Viewer > Window Logs > Application and found the errors, here are the errors related to vMix:

Also found these 2 around the same time, unsure if these are related:

Unfortunately the randomness of these errors, and the fact that other applications are crashing randomly too most likely indicates faulty hardware.
(Especially if reinstalling Windows did not help)

This is usually something like the motherboard or memory unfortunately.

There is an app in the start menu called "Memory Diagnostic" that can be used to test the memory.
Also, if the motherboard has two memory modules installed, you can also try removing one of them making sure PC is turned off at the wall first.
When powering back up, if things have not improved with only one module repeat these steps but swapping out the other memory module instead.
Also double check the motherboard manual to ensure the module is installed into the correct slot.

If the above memory tests do not help, then you an also run a test with all the PCI-E cards removed.
Then if it works, try adding them one at a time, testing each time until the failure occurs.

Hope this helps.

I was able to look up the Support Reports you sent, and there are other apps crashing in the past.
After the reinstall they won't be crashing anymore as they have not been running by the looks of things.

Also, some of those apps are behind the scenes system services in Windows, so you may not see any error messages appear
but they are definitely failing, and why it is most likely faulty hardware.

One more question please; if it does come down to replacing either/or both the memory and motherboard, are their any recommendations on brands/models that play nicely with vMix? Thanks.

Thank you

Have you also checked for BIOS updates?

Yesterday we replaced both the motherboard with (ASUS ROG Maximus Z790 Apex) and RAM (2 x 32GB DDR5 Kingston) in line with the vMix reference system Topaz: https://www.vmix.com/pro...rence-systems.aspx#topaz

Big expense, but we needed a resolution asap, sadly that didn't seem to have made any difference, still crashing.

We ran the Furmark graphics card check, whilst it came up with a satisfactory score, it did crash vMix as I had that running at the same time. CoreTemp is reporting an average of 52C per core.

Have sent another report from within vMix to vMix support, will wait and see I guess. We are at a loss and have no idea where to go from here, but we know it’s costing us a lot of money in hardware and time ☹

Hi Martin, not sure if you're around to see this, but we were going so well, and now more crashes. I have sent another report from within vMix.

Now we are getting desperate, I’m not sure what else we can do, below is everything we have tried.

The crashing seems to be stemming around us adding any devices to the PC, vMix just doesn’t like it. We are adding USB Audio Interfaces to be able to route the zoom inputs (4) out to our radio audio console. Is there another way we can move the audio? Dante or something else, my knowledge is limited with this?

- Replaced Motherboard, Graphics Card and RAM with https://www.vmix.com/pro...rence-systems.aspx#topaz
- Reinstalled Windows 11 twice
- Removed (2) Tascam USB Audio Interfaces and drivers/software, replaced with M-Audio M-Track Solo & Fosi Audio DAC-Q4
- Slowly reintroduced required cards and devices over a period of 3-4 days

Crashing recommenced after last 2 new USB audio devices and drivers were installed yesterday (M-Audio M-Track Solo & Fosi Audio DAC-Q4). Prior to this we were getting no crashes.

We also added our Stream Deck XL and software in the last 24 hours, could this be it? This has since been unplugged and software uninstalled, PC restarted, but it still crashes.

We are also getting some Anydesk crashes on that PC, this software is needed for our remote staff.

Latest Event Viewer crash log:

Any help would be greatly appreciated.

Thanks for the tip, cheers

I am always hesitant, to use even two audio interfaces, because I read about possible problems, and was able to avoid it so far.

It should be possible, but seems to have to be setup properly, see eg. https://recordingtec.com...her-and-why-you-should/.


(Btw, you wrote that you want to output 4 Zoom inputs. Shouldn't the Tascam US 4x4 HR be able to handle it alone?)
