Issue Description
Getting this repeating error upon PIE. Unable to find source of issue, even removing all sources/listeners and rebaking does not seem to fix/remove issue.

LogSteamAudio: Warning: Warning: apply: invalid void*: params->ir = 0000000000000000
LogSteamAudio: Warning: Warning: apply: invalid IPLint32: params->irSize = 0

@Gombles A few quick questions:

• Is Enable Validation checked in your Steam Audio settings?
• Are you using convolution reverb, parametric reverb, or hybrid reverb?
• Are there any other issues you are experiencing, like crashes, or incorrect audio?

If you are using parametric reverb and there are no other issues, this may be a case of overly aggressive validation, where the validation logic is complaining about a convolution IR not being set even though it doesn't need to be.

@lakulish Thanks so much for your reply.

Yes enable validation was ticked (not entirely sure why/when)! This seems to fix the issue. I was using convolution so was doubly confused about the error being around IR size, the audio seemed to perform fine.

My only issue at the moment is baked reverb/pathing not seeming to work but that is a whole separate issue.

Thanks again for your reply :)
