After upgrading to the latest amd64 snapshot, OpenAL is broken now and no longer produces any sound. It was working for me using 1.20.1 previously.
I tested with ioquake and several games playable using fnaify and libgdx/lwjgl{2,3}. No issues with others ports using e.g: SDL2 sndio backend for example, or audio playback in chromium. -Bryan.
