The AM Monitor shows to working flow of the AM. In this demo, we use the AM with 2 Plugins for PulseAudio and Audio Policy Control. When we play the audio in this app, we can see the internal status of connections in AM and status of the PulseAudio.
- Audio Manager (branch Intreprid_stable_branch, Version 6.1)
- 2 patches for PulseAudio Routing Plugin and Audio Policy Control Plugin (http://git.projects.genivi.org/?p=meta-genivi-demo.git;a=tree;f=recipes-multimedia/audiomanager/audiomanager;h=f134ecaf6190ec272bd6136ee88f0e86a8b86047;hb=HEAD)
- PulseAudio
- DBus
- Qt5
- Python
- sqlite3

If you have a trouble with the compile due to not enough memory (e.g. build on VMWare), You can comment out the line "RESOURCES += qml.qrc" from AudioManager.pro. The executable binary won't have big resouce files in it.
$ vi AudioManagerMonitor.pro # comment out line "RESOURCES += qml.qrc"
$ qmake && make
$ ./AudioManagerMonitor --debug # run with --debug to load resources directly from filesystem.
Or you can add swap file temporarily for enough memory space for build on VM.
$ dd if=/dev/zero of=/swapfile bs=1K count=2000000 # 2G, you can try more
$ mkswap /swapfile
$ swapon /swapfile
$ # if you want to use this for next boot, add "/swapfile none swap sw 0 0" in /etc/fstab and reboot
-
Set testing environment
$ . pc-env
This script creates 2 virtual sink device for PulseAudio Daemon. You can check with "pacmd list-sinks". If you want to remove created sink device, execute 'deactivate' on the shell
-
Execute AM
$ AudioManager -V -c(PREFIX-OF-AM)/lib/audioManager/control/libPluginControlInterface.so -l(PREFIX-OF-AM)/lib/audioManager/command/ -r(PREFIX-OF-AM)/lib/audioManager/routing/
-
Execute AM Monitor
$ ./AudioManagerMonitor --debug
If you don't use any argument, AM Monitor will be running as fullscreen mode. Please refer the usage with "--help" option.
- Preset of AM Sources and Sinks (PREFIX-OF-AM)/lib/audiomanager/routing/libPluginRoutingInterfacePULSE.conf It defines 5 preset of AM Sources - Entertainment, Navigation, TTS ...
- Policy Rule (PREFIX-OF-AM)/lib/audiomanager/control/libPluginControlInterface.conf It defines audio policy scenario. E.g - When play the NAVI sound alert during Media playing, Sink Volume of previous Media goes down to 50%.
