Feature request: wrapper for libjack.so.2
Hi! I am trying to use a combination of `box64`, `wine64` and [yabridge](https://github.com/robbert-vdh/yabridge) for running x64 Windows audio plugins on my Raspberry Pi 4. I am already able to use these three together, but then to launch the plugins, I need to run an x64 plugin host like [carla](https://github.com/falkTX/Carla), Ardour, Qtractor, Element, ...
I have tested all of the clients above, but none of them work with `box64` except for `carla-single`, a subproject of `carla` that provides a command-line tool for launching plugins.
The problem is, `carla-single` relies on `jack` for the audio input/output, and there seems to be a communication issue between the client-side (`libjack.so.2` is emulated) and server-side (native `jackd` audio server running on ARM). The `jackd` server quits with a segmentation fault when `carla-single` tries to connect to its channels.
I think that wrapping `libjack.so.2` can solve this issue. Is it something doable?
To troubleshoot this, I open two consoles, one for launching `jackd`, and another one for launching `carla-single`.
This is the output of the console running `jackd`:
```
