Will this issue ever be properly addressed ?

Could unity point me to a changelog that in any way references this issue? I went through every beta I could access as well as the full releases and I could not find any references to this issue number (under "known issues" or "fixes"). Although a number of pages 404'd me.
Has it just not shipped in any beta release yet? Or was it just left out of the patch notes?

Has the fix for this bug been backported to any other unity releases? If so, which ones?

I agree. This was closed without proper thought into the problem.

Hello,
I believe this is incorrect.
If you look at the example included in the documentation you just linked, you can see that the AudioSettings.dspTime is being accessed from within the OnAudioFilterRead function.
The issue is not with accessing general Unity API, but the audio specific one, which should function correctly from within the audio thread since that's its intended usage (according to the official documentation).
It works correctly under Windows and Android and is crucial for using the OnAudioFilterRead code (including the official example). Can you please look into this again?
