SW KOTOR 2 Crashes when trying to change

[UserGit-2021]

KOTOR 2 crashes when trying to change EAX1, 2 or 3 version in game. But the main menu does not crash when changing or disabling EAX. Creative ALchemy also tends to crash.

Given that it crashes with ALchemy too, I'm inclined to say it's an app bug. Perhaps some data that doesn't get updated correctly when switching EAX modes during play, causing it to use freed memory or invalid parameters that aren't handled properly. The DSOAL log doesn't show anything wrong, while the ALSOFT log shows the app specifying a bunch of invalid parameter values and sizes at the end.

The game uses Miles, and there's debate about the relevance of its version.
I suppose testing should be attempted on XP to be really sure.

I checked out both versions and here's what I found:
1.0 and 1.0b official update - Miles Sound System 6.6g (6.6.7.0) (hashes match too)
Aspyr 1.0b update - Miles 9.3u (9.3.20)
Also tested EAX switching on Windows XP with X-Fi hardware and it seems to work fine https://youtu.be/yBoFtfObyFY

Using recent builds of OpenAL Soft and DSOAL with SW: KOTOR2 in Wine, I experience no crashes when changing and submitting the EAX setting at Iziz Spaceport. I do however have the TSLRC mod v1.8.5 installed, which might contain a fix for this(?).
