Hi! Thank you all! I didn't know about band-aids project, I'll take a look as soon as I find something useful to resolve the bug Jim sent (I'm still trying to reproduce it)
@Andrea: I don't have a blog, so I'll just write here few lines about the app. The backend is a Qt DBus client that consumes PulseAudio (especially org.PulseAudio.Ext.StreamRestore1 [1] interface) and com.canonical.indicator.sound services. Looking at System Setting source code I found how volume setting works ([2]) and inspected the DBus service in Terminal to find a way to set microphone volume too, I found mic-volume org.Gtk.Action and implemented it, this was easy after reading system-settings and indicator-sound source codes (and a lot of documentation). Later, searching for a way to control a single role volume, I found bug #1368827 [3] which explains how roles works in Ubuntu Touch and implemented PulseAudio service too. I think this was really a good exercise, I learned a lot about DBus developing it :) Thank you again, Devid [1] https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/Developer/Clients/DBus/StreamRestore/ [2] http://bazaar.launchpad.net/~system-settings-touch/ubuntu-system-settings/trunk/view/head:/plugins/sound/PageComponent.qml [3] https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1368827 On Mon, Aug 1, 2016 at 12:03 PM, Andrea Bernabei < andrea.berna...@canonical.com> wrote: > > > On Fri, Jul 29, 2016 at 9:06 PM, Devid Antonio Filoni <d.fil...@ubuntu.com > > wrote: > >> Hi guys, >> >> > Hi Devid! > > >> 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).
