audioContext() is undefined when using -s PROXY_TO_PTHREAD=1

[Jonathhhan]

audioContext() is undefined, if I use PROXY_TO_PTHREAD=1. Maybe it is not proxied to the pthread?

What code are you calling that requires AudioContext? Is it part of the emscripten SDL implementation?

I did not use SDL, but the audioWorklet example https://github.com/juj/emscripten/blob/audio_worklets/test/webaudio/audioworklet.c and some Open Frameworks patches.
Those issues seem to be related:

So it looks like AudioContext doesn't exist in workers so if you want to use it from a pthread you would need to proxy those calls back to the main thread. There are several different ways to do that but a good place to start would be https://emscripten.org/docs/porting/pthreads.html#proxying
