Cannot use ASIO4ALL V2 Playback Engine. Assertion error line 994. Unable to fix.
I had been using the Pro Tools 2019.12 software while without inconvenience.
However, I had to install an ASIO4ALL driver because my PC only had a Windows Audio Device Playback engine and that one doesn´t allow me to preview video. I cannot enable the video engine with this Windows Audio Device Playback Engine. I need the video playback because I am using Pro Tools for Video Post Production. Thus, I installed ASIO4ALL and it allowed me to work as I intended. I was Using the ASIO4ALL V2 Playback Engine. Until, unexpectedly and inexplicably, it stopped working. One day, I started my computer up and opened the project that I was working on (as I had been for a while) only to be greeted by this error message: "Assertion in "E:\ Code\ 238957\ ProTools\ AAE\ Source\ AAX\ CFicAAXWidget.cpp", line 994." Which prevented me from enabling the ASIO4ALL Playback Engine. Even If I clicked "Ok", the software would present this error message: "Access violation occurred, unable to read location: 0x0000000000000000" Naturally, I copied this messages and browsed them on the web. And I came across some of your Community Forums, where the only advice I could find was to clear the delete the "Pro Tools" Preferences folder in my computer. Here I present the links to your Forums which led me to through this process: https://duc.avid.com/showthread.php?t=405443 http://avid.force.com/pkb/articles/e...t-cpp-line-822 http://avid.force.com/pkb/articles/t...ide#delete_pro So I deleted my Pro Tools Preferences. Following each of those steps. Then I restarted my computer. I opened Pro Tools again and tried to set ASIO4ALL V2 as the Playback Engine. And the program gave me the same error message: "Assertion in "E:\ Code\ 238957\ ProTools\ AAE\ Source\ AAX\ CFicAAXWidget.cpp", line 994." The same problem. Please help me. I don’t know what else to do. I have tried this solution several times by now, to no avail. I have even tried uninstalling all of the avid programs from my computer, as well as asio4all; and reinstalling it all over again. Still the same: "Assertion in "E:\ Code\ 238957\ ProTools\ AAE\ Source\ AAX\ CFicAAXWidget.cpp", line 994." Here are my device´s specifications: Processor: Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz 2.21GHz Installed RAM: 64.0 GB Windows Specifications Edition Windows 10 Pro Version 1903 PLEASE HELP. Thank you in advance for any input on this. |

First, do yourself a favor and get a real interface, second, have a look here:

As The Weed has said, the answer is a proper audio interface with its own asio driver.
