@DrSanjeep Could you provide either a) detailed steps for reproducing this issue starting in an empty/minimal Unity project, or b) a minimal Unity project that reproduces this issue, or c) a crash dump file that we can inspect? We will try to reproduce this issue on our end, but more detailed information will help us a lot. Thanks!

[DrSanjeep]

@lakulish sorry where do i get a crash dump file on meta quest 3?

[DrSanjeep]

same issue with unity 6000.0.22f1

[lakulish]

@DrSanjeep You may be able to obtain a crash dump from your Meta developer dashboard. If that is not possible, you could provide us with a minimal Unity project or more detailed repro steps.

[DrSanjeep]

DrSanjeepNullDeref.zip the minimal project @lakulish ... it will not crash if you change to convolution mode, in case that helps. thanks

[DrSanjeep]

@lakulish as you can see, to crash on android, just enable Parametric

[lakulish]

@DrSanjeep I noticed a couple of issues with the way things are set up in the project you provided:

1. There doesn't appear to be any baked reverb data in the probe batch. If you look in the Detailed Statistics section of the Steam Audio Probe Batch component, it only shows "Pathing". You will have to bake reverb from the Steam Audio Listener component, as described here.
2. In the Steam Audio Settings, the option to save parametric reverb in the baked data is disabled. You will have to check "Bake Parametric" in the Steam Audio Settings.

Can you try the above two steps, i.e.: first enable "Bake Parametric" in the settings, then bake reverb for the listener, and see if that helps with the issue?

[DrSanjeep]

yes that was the first thing i tried

[DrSanjeep]

@lakulish is that it then? any plan to fix it, or improve the error handling?
