Ok, I'm having a major problem here. I'm getting random crashes. Either it's shutting down the machine, or, just a few minutes ago, a BSOD. Thankfully it wrote a DMP file.

I'm trying to LEARN to use a DAW (Reaper) and I have Potato installed. I'm also interfacing with MuseScore, a notation program that can play back the score you create. I'm taking a music theory course, and this is a necessary tool for the course.

I have the ASIO4ALL driver installed, and it works...except for these random crashes. This is the first crash where I got a dump file out of it, so this is the first time I could analyze anything. In the analysis of the DMP file with WinDbg Preview, it appears to be the ASIO connection that's failing. So I searched for that on the web. Turns out there's an issue using ASIO4ALL with Voicemeeter, primarily being that it's not necessary, according to the documentation. But I'm at a real loss to figure out how to get rid of ASIO4ALL and instead use the built-in ASIO in Potato. Are there instructions for getting it to work with a DAW? I have never done the more advanced things with VM, such as "patch insert" or anything like that, so #ExplainItToMeAsIfI'mFive, if someone could please take the time. I don't want my system to get damaged by these crashes. I've tried everything else I can think of, and it's only because this dump analysis mentions Voicemeeter that I'm even going down this route.

I searched the Forum topics, and while there's some stuff about DAWs, they're mostly CUBASE, which I don't use, and it's all old, from last year sometime. So can someone please help me out and tell me what I've got messed up and how to un-mess it? I'd really appreciate the help!

I got WinDbg Preview loaded, and this is the result of analyzing the file:

By the way, you should have a talk with your course handler about removing the evil Muse Group from their curriculum. Frankly after their repeated attacks against both the musician and programming community, I outright refuse to use their software at all, and you should, too.

Now that we have that out of the way, this one is interesting because a BSOD means a hardware fault or an error in the driver handling that hardware. Looking at the dump I don't see any sign of ASIO4ALL (but you said you saw the ASIO connection in the dumps? Am I missing something here?) and it really looks like the VM cable crashed but obviously that's not normal, so that leaves us with the question of why it crashes on your machine but nobody else's.

First and most obvious thing would be to completely uninstall and reinstall voicemeeter, but I'll assume you already tried that (including all of the reboots and everything as per the instructions on this forum). Next up I'd be looking at disk corruption. Just run chkdsk on it and see what it says. I can't help but wonder if you have your PC overclocked. If you do, clear your CMOS and run it stock and see how you fare.

More logs is always good

Let us know how it goes....

I'd like to chime in with a few things:
- The crash itself seems to occur in the VB VAOI driver (vbaudio_vmvaio64_win10).
- Perhaps ASIO4ALL hooks itself into existing AIO implementations? This is a stretch, so I don't know.
- You should be able to safely get rid of ASIO4ALL and switch your inputs to VAOI. These devices should also properly show up in Reaper.
- An DRIVER_IRQL_NOT_LESS_OR_EQUAL is the fancy driver way of saying "Access Violation" - the complication here is that these can also be caused by memory module errors. As xcasxcursex mentions, a chkdsk first is a good bet, then a BIOS check to see if your memory settings make sense. If you've tuned your memory, it might be unstable. If you have not, you might be looking at faulty RAM. Download a copy of Memtest86 and write it to a USB pendrive - if it shows any errors during the tests, you're looking at a hardware problem.
