The thing is, it says 6 but I had like 12 tabs open. And no audio was playing.
The audio object was not even in use.
With zero sound playing it makes me feel like it is a construct 2 issue.
My drivers are up to date.
Using built in audio on my p9x79 pro motherboard.
This shouldn't be an issue for any end user. But the server side of things means there could be limitations on how many instances/rooms/ map regions are hosted.
I think if you ask musician, you could get a good answer.
Anyway, just my 2 cent, I'm possibly wrong here but here goes nothing.
I played around some DAW 2-3 years back, thing that I learn is, depended on your sound card, it possibly can handle a limited number of source. The phrase "audio context" seems familiar to me, I think you have reach maximum supported source, that's why you got that error. In your case, amount of source used is 6process * 12 tabs, means you have total of 72 source. A single process could have more than 1 source (precompiled lossless audio), but that is unlikely because your audio should be in the compiled format, so it counts as 1 source.
As far as I know, modern computer can support either 32, 64 or 128 source. I think your sound card support 64 source as once it crossed the 64 limit, the sound card will just stall. I don't know the max supported source for highest-end card, but professional musician normally use 128, and that is already considered overkill by most people.
