I am trying to use Picovoice on the Tinkerboard 2S and I am getting these logs when trying to initialise a process

permission to record audio from the user.
Firstly, I have the right permissions in the Manifest and I have validated that the permissions are enabled for audio recording through the device as well, as well as requesting the permission at runtime when the app is first installed.
I have gone through the Java source code and can't see why it'd be wrong there, and it does seem to be in the native libraries. I really don't know what could be causing this. I have tried to initialise the process at different times, well after everything else in the system is initialised, but no luck. I have tried a few different versions of Android for this board, but still not luck there.
I have also asked this question in the TinkerBoard forums, but I am asking here since maybe it is more generic to the OS.
Update: I have noticed that I do not have pcmC0D0p in the audio devices directory.

Is it safe to just change the naming of these to see if it fixes it?
