Ubuntu16.04下，Qt5.6 aml audio无声音

参考资料：https://forum.qt.io/topic/67338/qtmultimedia-work-with-gstreamer-1-0

https://sites.google.com/site/easylinuxtipsproject/multimedia 关于 sudo apt-get install ubuntu-restricted-extras 的，但问题依然没解决

控制台显示以下错误：defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"

 

执行 $sudo apt install libqt5multimedia5-plugins,故障依然

sudo apt install libgstreamer1.0-0 故障依然

 

安装 $sudo apt install gstreamer0.10-plugins-base 上述错误消失，错误提示在点击播放按钮后提示：

$sudo apt install gstreamer0.10-plugins-good 后
