[Devid Antonio Filoni <d.filoni@xxxxxxxxxx>]

Hi guys,

this is my first message on an Ubuntu mailing list after years so I would
like to spend few words for my apologies: I was an active Ubuntu
contributor many years ago (MOTU, SRU, translations...) but due to personal
matters I was not able to "properly contribute" anymore, I also started to
work as web developer and my employment was horrible in a such way it
alienated me from the Internet world (not only Ubuntu). I'm really really
sorry this stopped me from being here around, I love(d) this community.
However, last year I got a job in a new company, fixed my internet
intolerance and so I would like to contribute again as I can! :)

I bought a secondhand Nexus 4 last month only to help development but I
liked Ubuntu Phone, so I'm a daily user. First I noticed an issue in the
microphone [1] and everyone in the bug report was asking for a way to
adjust microphone volume. Looking for that I found a post in this mailing
list [2] about volume roles and (also) the fact there is no way to know
device volume levels.
I decided to write a simple app to control speakers, mic and roles volume
levels in order to develop in C++ (like it), learn Qt/QML and find more
about ubuntu-sdk and phone system. I'm sharing the code I wrote in last two
weeks, it is almost ready and the app works fine. I won't publish the app
in the store because I don't know if you'll approve its usage and, as it
uses DBus services which are not handled by apparmor policy, the app is
unconfined. I also think this app should be used only by experienced users
(for example: I still don't understand some roles purpose only by their
name but my english is not really good as you can notice in this email too,
so maybe it's just me) and usually they're able to build a source code ;)
Everyone can fork it, I think it's a good learning project. Please tell
(you can also insult) me if I did something wrong in the code, any
suggestion is welcome, sharing is good for humanity knowledge :)
Code: [3]
Screens (imgurl album): [4]
What's missing: app doesn't intercept roles volume change from other apps,
I don't know which apps change roles volume. I'll try using terminal.

Now the real question:
How can I help Ubuntu Phone development? I would like to focus on "backend"
stuff such as libhybris, aosp, aethercast (I don't have a WifiTV :( ) and
so on but I really don't know where to start from, I don't even know
installed core libraries, actually IMHO wiki is not very updated/useful in
this (it's app-oriented). Is there any
important/asked-many-times/low-priority-due-to-resources bug open I can
work on and involves core-developing? If it is difficult don't worry, I
like to get my hands dirty on code, if it's really difficult I'll tell you
I'm not able to work on it but please take a look at my code before
pointing me to an issue/wishlist, I'm sure I'm not a real C++ developer
(missing exp) but I'm not sure I'm not a bad C++ developer :D and I don't
want you to lose your time reviewing bad/useless merge requests, I can help
in other ways (translations, etc...)

Thank you!
Devid

(I'll be on holidays next week and I wan't be able to reply to this thread
