Yeah. v1.x had a recurring issue of simply not working on multiple devices. I doubt this was related to the Aseprite version, instead I think it’s related to how it used memory peeking on other applications (which is considered unsafe and might’ve been blocked by the OS or anti-virus – with very good reason I might add).
Aseprite Audio Extension has only consistently worked on my machine (running on Intel). v2.0 should fix any issues since it changes the way that the values are accessed (it now uses a Lua script).
