We have reported it several times to vMix support sending the reports from within vMix, who have suggested a few things, but nothing solid at this point. We are starting to question do we even purchase vMix as we are only still on a trial, if this is going to be what it's going to be like, but I'm hanging onto to the many posts here saying that their vMix is "running rock solid!".
The main offending DLLs that seem to always show up in Windows Event viewer are:
(ntdll.dll - mainly this one), AppXDeploymentClient.dll, unknown, Windows.FileExplorer.Common.dll
Is this a vMix memory leak problem? We are on Windows 11, is vMix even supported on 11? Should I roll back to 10?
The vMix GPU memory sits anywhere between 50%-58%.
New PC: i9 13900K 24 core LGA 1700, NVIDIA RTX 3070 Ti, 2x 2TB 970 EVO SSDs, 128 GB DDR5
Here is what we have tried, some suggestions from vMix support, others from forum posts:
- Complete Windows and software reinstall and ensured all updates and drivers are up to date
- Installed WhoCrashed, ensured the dump files were configured, but it did not generate a dump log, even after a reboot
- Turned on FEIM for each of our 4 NDI inputs (Zoom Rooms)
- Ran vMix Diagnostic tool - Results: No background Graphics Card applications detected. SCAN COMPLETED SUCCESSFULLY
- Purchased a 2nd PC for mail, browsing, skype etc - ensuring the vMix PC is solely used for vMix only
We also have the following PCIe cards installed (Blackmagic Decklink Mini Recorder HD card, Soundblaster Audigy Fx sound card, Xonar sound card) and 3 x USB Audio interface units installed (Behringer UMC 202HD, Minifuse 1, Tascam US 2x2 HR, Tascam US 4x4 HR) - all drivers up to date.
I'm at a loss as to where to go from here, vMix support are hinting it may be a hardware conflict, but wanted us to do the OS and software reinstalls first. Can anyone offer any advice? I'm happy to pay anyone who can assist in diagnosing and fixing the issue, I really need to get this ASAP. Thanks in advance.
Hi, I am late to this but would like to leave my thoughts here: Your USB Audio Setup looks pretty ambitious: 3 USB audio devices might be fighting for USB bandwidth and/or IRR ressources in your system. How well this works depends a lot on the USB host controllers on your mainboard and their respective capabilities. Probably none of the vendors has tested this combination. If I had to debug this, I would install Windows from scratch, install Blackmagic software and vMix and start testing. Than add one component after he other and keep testing. With USB audio, I would go for one multichannel interface instead of this complex setup. I am quite happy with he MOTU 1248, but you might find other devices to suit you better. Maybe connecting a full blown audio mixer with multichannel USB support is also an option in you workflow. Running all the stuff on Windows 10 is also a good idea - if your PC system supports this. Please keep in mind that vMix sits on top of all device drivers, so vMix crashes can easily come in fact from driver crashes. I hope you solved your problem in the meantime. Best, Christian
