LuCI FINALLY !
With some difficulties (and thanks to various LLMs support), we finally managed to create a fully working (in conjunction with CGI and CLI control modes) basic LuCI page.
We also implemented the connected audio interface probing to verify its parameters.
Last but not least, we've "packaged" everything into a single installation file for a simpler approach.
We're already discussing upcoming improvements, stay tuned !
