Topic: American Audio VMS2 Mixer Download Failed and DRIVER_POWER_STATE_FAILURE
Hi All,

You can skip to QUESTIONS below if you don't want to hear the backstory.

I was hoping for some help or insight. I was holding back updating my ~3 year old laptop to Windows 11 and finally did.
2 problems I had.
1) I was getting a DRIVER_POWER_STATE_FAILURE blue screen anywhere from a couple minutes to maybe half hour after I started VDJ in which it would restart the laptop. (That was my main issue)
2) When I start VDJ it gives a VDJ dialog title DOWNLOAD with the content American Audio VMS2 v8.zip download failed.

I reached out to VDJ support and they didn't think my issues were software related and recommended I contact the mixer vendor which I did. It was nice they helped me with this old model but they couldn't help either. It seemed like they felt it was 2 things. The laptop crash was Windows and the download failed was VDJ.

The kind of good news is I might possibly have found the issue with the crashing. After doing all the standard procedures:
Trying different USB Ports (I actually tried 2 other PC's too)
Checking for Updated Drivers
Checking for Windows Updates
Disabling Power Mgmt on USB Ports
Run SFC & DISM
Analyzing the Minidump File
Checked for Malicious Scripts & Startup Tasks
Removed possible corrupted or malfunctioning shell extension (Open Shell)
Checked Task Scheduler
Checked Autoruns
Last Step MSCONFIG disabling non-MS services

That last step clued me in a bit. After disabling similar groups of services at a time I got to my NVIDIA services and disabled them all. Now I was able to run VDJ for 2 hours twice without a crash and trying a 3rd time this morning. So I might now be left with figuring out why VDJ is still having that download failure during every launch.

I did remove all plugins/addons which I even saw there was one for the VMS2. I am fine with the default pro screen and don't need a different layout. So here I am now:

My 2 QUESTIONS:
This is a dedicated DJing laptop so do I need all of those NVIDIA services running all the time? For better stems or anything else? I could have sworn (but can't say for certainty) that I updated the NVIDIA drivers recently and before I went through all the troubleshooting steps I should have confirmed that as one of my first steps. If I can do without them great since I fear installing another possible newer driver could cause more unnecessary time when it's working now. If it's not broken.. :-/

What is VDJ trying to download since I already have the latest VMS2 driver with American Audio tech confirmed.


Why not upgrade my mixer yet?
1) Money is tough now.
2) I got so used to this unit.
3) The integration in my case makes it light and quick to get going. This ADJ VMS2 just fits in an SKB 4 space case that I mounted a slider shelf which it fits on top of. There is also a spare space on top that I mount my wireless mic transceiver. Basically I get to a party and slide out the shelf and everything on the mixer and mic side is already plugged in so it's a quick setup. The hard SKB case also makes it easy for me to have my laptop at a great position on top closer to me unlike some others that are used to reaching across their slide back unit.

Thanks for any and all suggestions/tips!

1) Generally speaking it's not a good idea to shut down critical services like nVidia.
VirtualDJ will use whatever your laptop has to display the GUI, but nVidia is needed for Stems 2.0

2) Most likely VirtualDJ fails to download the special skin that was designed for that unit. It's not necessary to use the skin, but VirtualDJ tries to download it anyway.
 
I'm definitely curious about the stems part. I enabled stems 2 on this laptop but how do I test how well it's working? Is there a debug feature in VDJ to do so?
 
No need for a debug.
Enable High Quality stems, and load a track on a deck.
If the track calculates it's stems in a reasonable time (let's say anywhere between 10 and 30 seconds) then stems are working fine.
 
Wow I never noticed the very tiny text saying "computing stems" and it's taking over 2 minutes per song but strange thing is that I've had vocals turned off early in a song and I don't see it having a problem with that.
 
It computes from the playhead, so the stuff right now is worked on before the stuff 2mins later in the track. Which most cases is best compromise unless you start bouncing around the track with hotcues or beatjumps.
 
Thanks for that clarity!
There was an updated NVIDIA driver which I just updated and I was curious if updating the driver and re-enabling the NVIDIA services meant a difference in stem computations, it seemed it didn't.
When no NVIDIA services were enabled ~2 mins/song
When NVIDIA was updated + re-enabled services ~2 mins/song
I'm going to disable HQ for now and if they ever find a way to get HQ to work with less processing power I'll jump at enabling it again.

Side Question:
I'm running an
i7-8750H
16.0 GB RAM
NVIDIA GeForce GTX 1060 w/6GB Vid RAM
~2 Mins Stems Calculation.

Is there a chart anywhere if one day I want to upgrade to a laptop that can handle HQ Stems much better? I'd love to see speed/time numbers
 
Some rough speeds..

RTX 2060: 10x
RTX 2070: 12x
RTX 2080: 15x
RTX 3060: 15x
RTX 3060Ti: 20x
RTX 3070: 22x
RTX 3080: 30x
RTX 4080: 40x

10x means that if a track is 3 minutes long (180 seconds) it needs 18 secs to get it's stems calculated, while 40x means that the same track needs roughly 4,5 secs.
