I got sound (grunts and groans but no music)
If you can describe with some details the issue you are facing, that will help to understand what is going on.
I had no idea how to use !UnixHome so I made it run on boot.
The error messages I get are 'The access details set for this file do not allow this'.
To use my Pi now I have to click cancel 11 times to get to the desktop and then once more to actually use it.
Most apps will now not run.
This persists despite removing !UnixHome
For future reference, for those new to RISCOS an indication when !UnixHome is required, a link to the correct version to use and instructions of what to do with it would be useful.
