New issue by fdziarmagowski on void-packages repository

https://github.com/void-linux/void-packages/issues/52753

Description:
Please consider adding Jack audio back-end to SDL2 and enable it by default. This is required for environments where Jack server is running and providing an audio interface for applications. Without it SDL2 applications fail to provide sound output to Jack
(_SDL audio device opening...failed (Audio subsystem is not initialized)_)

Proposed patch:
```diff --git a/srcpkgs/SDL2/template b/srcpkgs/SDL2/template
