Feel free to post a callstack you get (you should be getting it in the \*.log file, but you can also run under gdb and do a bt). I think opening a new AnswerHub question would be more appropriate for it (other users will have it easier to discover without having to read all the thread above). ---

Hi, Just to clarify, you are replacing the libopenal.so.1 in the packaged output of the project right ? Also is there a publicly available project that runs into the same issue you are seeing ? I can give it a look. Thanks ---

I replaced both libopenal.so & libopenal.so.1 to the C:\UnrealEngine-4.6.1-release\Engine\Binaries\Linux can you show me where is the tread discussion? ---

Hi, I received through email your comment that you can’t find libopenal.so for linux-arm, which seems to have been solved. For some reason I can’t find that comment here. Does this mean you were previously using a different file for libopenal.so ? If so does using the new file fix the crash issue ? ---

it turn out that my Jetson’s audio is not functional in Linux, it shows no audio devices, that is why i believe is the problem… does your audio works? or does it show a X on the speaker? ---

My regular install of Jetson TK1 has audio working. I verified this by plugging in a headphone and doing a sound test from within ubuntu. I didn’t do anything special. It seemed to work from just standard installation. Unfortunately I don’t think SunTemple has audio. Do you have any simple demo app with audio that I can try ? ---

Hi! I’m stuck on this last step (replacing the libopenal.so file). I’m on UE4.19 and have successfully built a simple project for Linux ARM, but when I go to the release directory\Engine\Binaries\Linux, there’s only one file: UE4Game-Linux-Shipping. Does this mean we don’t need to replace libopenal.so anymore on UE4.19? Thanks a lot in advance 🙂 [Previous page](https://forums.unrealengine.com/t/arm-linux-compile-for-arm/295252.md?page=1)
