I am using voxl-px4 version 1.4.26-202209151733. I was not able to find the file /etc/modalai/quad_x_io.main.mix. It is is missing. How to solve it ?

Hi @Tamas-Pal-0 ,

Sorry there's a typo in the docs I will fix now, but here's where the files live:

```
voxl2:/$ find / -name *.mix

/usr/lib/rfsa/adsp/quad_x.main.mix
/usr/lib/rfsa/adsp/quad_x_io.main.mix
```

The mixer and PX4IO drivers run on the DSP and this is the location for it's 'file system'.
