cmusbdac.sys SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M BSoD

[MAC329]

Hello, there are a lot of forum posts about this, however none of the solutions have worked for me so far, basically I'm getting BSoD after playing a game for about 10 minutes. the message says something along the lines of cmusbdac.sys failed or SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M. I know the reason for this crash, it's because I have my blue snowball microphone plugged in which is USB as other forums have said, USB mics cause this. This was happening to me a couple of weeks ago but I updated my audio drivers and that fixed the problem until today, which I did try reinstalling them again with no luck. My GPU has the lastest drivers as well. The only thing I am confused about is why it's saying it has something to do with C-MEDIA which I believe has there own drivers, but I don't have any C-MEDIA drivers on my computer in the first place, only realtek. I have contacted microsoft, asrock, and blue customer support with no luck. I have the dump file and my specs, here is the .dmp:

crash dump file: C:\WINDOWS\Minidump\071717-13640-01.dmp
This was probably caused by the following module: cmusbdac.sys (CMUSBDAC+0x387047)
Bugcheck code: 0x1000007E (0xFFFFFFFFC0000005, 0xFFFFF803F3047047, 0xFFFFCD819D1640B8, 0xFFFFCD819D1638F0)
Error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M
file path: C:\WINDOWS\system32\drivers\cmusbdac.sys
product: C-MEDIA CMUSBDAC Audio
company: C-MEDIA
description: C-MEDIA CMUSBDAC Audio Driver
Bug check description: This indicates that a system thread generated an exception which the error handler did not catch.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: cmusbdac.sys (C-MEDIA CMUSBDAC Audio Driver, C-MEDIA).
Google query: C-MEDIA SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M

Specs:
GPU: EVGA GTX 1050 ti SC

CPU: i7 2600k @ 3.4 ghz

MOBO: ASRock z77 extreme4

not entirely sure what else you might need, if there's any other information I could give that would help, I will be happy to give it, thanks for the help.

C-Media USB Audio Class 1.0 and 2.0 DAC Device Driver. Don't suppose you used any add on cards?

your board has a Realtek Audio so it doesn't use C-Media as from what I can tell, they are competitors

Have you ever used a 3rd party driver updater to install drivers as they can install the wrong drivers,

In device manager, what is showing under Sound, video and game controllers? hopefully just nvidia HD Audio & Realtek HD Audio
you can also show all unused drivers by - Click View tab in device manager and select Show hidden devices. Expand the branches in the device tree & look for the faded icons. These indicate unused device drivers. Right-click on any and select Uninstall.


Can you follow option one here
and then do this step below: Small memory dumps - Have Windows Create a Small Memory Dump (Minidump) on BSOD

that creates a file in c windows/minidump
copy that file to documents
upload the copy from documents to a cloud server and share the link here and someone with right software to read them will help you fix it

the dmp files might show more information.

I've never used another program to install drivers, nothing C-Media is in my device manager, just NVIDIA, Blue (my microphone), realtek, intel, and microsoft. What do you mean by add on cards? and I also copied what the dump file said based off WhoCrashed. I also checked my bios, it's up to date.

I suspect its actually the Blue Snowball itself. The chip inside the microphone - https://scottlinux.com/2012/07/23/blue-snowball-usb-mic-linux-compatible/ - is made by C Media.There don't appear to be any drivers for it - http://www.bluemic.com/products/snowball/#download-driver

Where did you get latest Realtek HD drivers? Not sure if updating them to latest from Realtek themselves would fix this, Now I search "blue snowball cmusbdac.sys" it all becomes clearer, people have been having problems like this for a few months.

I wish I had an answer for you.

people can extract a lot more info from the dump files than what who crashed shows, it might reveal another reason for errors. worth a try.

Okay, one thing is CMUSBDAC.sys is in my system32 file under drivers, would deleting that mess up windows? and I updated my realtek drivers from the asrock website based on my mobo, that fixed the problem for a little bit but it started happening again yesterday. How can I share the dump file? google drive and drop box won't upload.

Hi, don't delete it. Go into Device Manager and right click on the mic (assuming it's listed) and choose Properties. Go to the Drivers tab and click on Driver Details. It will show the files that the mic is using. Is one of the files the CMUSBDAC.sys? If so, the mic requires that file. If not, then look for other devices that might be using the file with the same method above (particularly any audio/video devices).

Okay, thanks so much for the help, I've done this and found the the driver is under the blue microphone so it must be the microphone itself, what should I do from here?

CMUSBDAC.sys is the driver implementation for integrated Digital to Analog converter chip used by Microphone. This chip can be malfunctioning/defect. Driver is loaded by kernel and because this you are receiving a BSOD.

Test the microphone on another PC, if you have the same result RMA the microphone.

Unplug the Blue Snowball
Download and install the ASIO4ALL driver Available from HERE, most users have reported this driver fixes an incompatibility between the Blue Snowball and Windows 10 . . .
Plug in the Blue Snowball and it should now work . . .

Thanks for another reply, I'm going to try it with the ASIO4ALL program going and hopefully it fixes it, if it works I will come back and make your comment the solution and edit this.

Edit: After a whole day, no crashes using ASIO4ALL, I'm having high hopes as normally I probably could fit 30 crashes in one day before.

I wish i had known that answer a few months ago when people were always asking about Blue Snowballs and I didn't even know what they were.

As to how driver got there, windows would have installed it when you first plugged Mic in. I expect the ASIO4ALL file is full of codecs, the name rings a bell from a long time ago.

Next time PC plays up when you plug something in, remember it can be the thing being plugged in causing the problems. I am not perfect, I ran into a similar thing last year when my speakers were dying, I kept blaming other things

Yea, I've seen a lot of forums and you've responded to most of them, with ASIO4ALL my pc is still working perfect with no crashes.
