Hello, new to the forum, but have been using OBS for years. Since before the Studio version.
Logging on today to report this crash problem. It's not hurting my system or affecting my usage, but it is a bit annoying.
Just today, I DLed and installed the most recent version of OBS Studio. I also installed the ASIO plugin, as that is something I have been longing for FOREVER, and have been fighting with trying to get it to work using that crappy VB ASIO Bridge BS, that I never could get to work right.
THANK YOU whomever made this new ASIO plugin for OBS Studio. Godsend!! I use it with ReaRoute, because Reaper is my DAW. It works PERFECTLY!! \o/ WOOT
Anyhow, the problem is this:
Every time I close OBS, it crashes.
Here is the uploaded log file from OBS: https://obsproject.com/logs/JD7p-luALdrZqJVp
Here is the windows output details of said crash:

Maybe something wrong with the hosting site? I see the Crash Reports only, under the link:

The second log, I'm asking about, is just obs session log or Log Files (there is info about loaded plugins, scenes, encoding...).

Yeah, but I think it is not from the attempt when OBS Studio crashed (in other words - the last log after obs was restarted after the crash).

It crashes every time I close it, so any log I post has certainly been involved in a crash.
I'll redo both here then.
Here is the crash log from the last time OBS closed and crashed: https://obsproject.com/logs/suqJf5uwZ5ZAyhDs
And here is the regular log file from the same session: https://obsproject.com/logs/YWmRVht380UC_PkS
I hope that works. :D
Sorry about all the confusion on my end.

hi im' one of the developpers of the asio plugin; the crash is indeed in the asio plugin when drivers are closed. For some reason portaudio library fails to close properly the driver.
That's not a super easy thing to debug because it can be due to badly written asio drivers (there are much more than one would think).
I need more info to debug:
- what is your asio device ? it is a focusrite, but which model specifically ?
- try closing reaper first, and then obs : does it still crash ?
- make sure that no other app than reaper is using your device (focusrite i guess)

It's a Focusrite Scarlett 2i4.
The crash happens even if nothing else is running, Reaper or otherwise. I just tried it, shutting down all other software, and it still crashed.
Here's the two logs:
Crash log: https://obsproject.com/logs/fJsKyC9s-D0vPk63
Session log: https://obsproject.com/logs/jj8kOdvMwSHmIzUP

Hope that's helpful.
And thank you SO MUCH pkv for the ASIO plugin. It's works wonderfully. So much better than that VB Cable ASIO Bridge thing. :D

ok i'll investigate; kind of surprised because I get no crash with the scarlett 2i4; stay subscribed to this topic.
I'm suspecting a regression. Could you try the previous versions of the driver ? they will get installed to Program Files (x86)/obs-studio/obs-plugins/64bit while obs 22 + installs in program Files so you'll have to copy manually the following file: obs-asio.dll
Try with V1 and V2.
You can post here the results or open an issue on github.com/pkviet/obs-asio

Sorry if I'm being dense here, but I'm not quite understanding what you mean.
RE: "Could you try the previous versions of the driver ? they will get installed to Program Files (x86)/obs-studio/obs-plugins/64bit while obs 22 + installs in program Files so you'll have to copy manually the following file: obs-asio.dll

I don't have any obs-studio in Program Files (x86) as I deleted them when I upgraded to the newest version of OBS. Should I totally un- and re-install?
Also, not sure what you mean by "Try with V1 and V2." ...... V1 and V2 of what?

Like I said, this isn't affecting my usage or the functionality of the software. it's just a minor annoyance. I'll stay subscribed and keep helping if I can.
Thanks. :D

here :https://github.com/pkviet/obs-asio/releases
There are two releases 1.1.0 and 1.0.0 ; you're using release 1.1.0. Test release 1.0.0.
For release 1.0.0 : there are two exe which correspond to 2 versions of the plugin called V1 and V2.
The installer for release 1.0.0 installs in Program Files (x86) because it was built before obs 22; you don't have to install an earlier version of obs-studio though. The obs-asio.dll for release 1.0.0 will be found there; copy to your current obs 22 folder (Program Files) and test

Okay, I have tested like you asked.
V2 of the of the version 1.0.0 release doesn't display this problem. V1 does.

@artao could you test this build ? https://github.com/pkviet/obs-asio/releases/tag/1.1.1
I've uploaded the dll and pdb files; you just have to swap the current ones with these (keep a copy of the previous since they were working)

Okay, did so. Still crashed upon closing OBS.
Crash log: https://obsproject.com/logs/1HVuBf2OA96yh9__
Session log: https://obsproject.com/logs/d5t7T7doY9ob1bJ9

EDIT: Oh dear. I made a grevious error. Previously, I hadn't tested the V2 1.0.0 plugin actually USING Reaper. I'd only tested to see if it crashed OBS Studio.
Sadly, when using the V2 plugin, I get no signal from Reaper. So yeah. I guess that one doesn't work right, even tho it doesn't crash OBS. Sorry to misinform you. My bad. In the future I'll make sure to test actually functionality instead of just whether it crashes or not. Oops.

ok np; both versions work with rearoute on my pc; i can't reproduce the crash so it's kind of difficult to troubleshoot.
Can you try the following ? with reaper, don't use the scarlett but something else, for instance asio4all or any other sound card. Does it crash again with rearoute in obs ?
