I installed Sailfish OS on a Nexus 4 to test Saera on a clean install of the OS. However, the microphone does not appear to be working. It also doesn't record anything in the Recorder app and leaves a message of 'no service found for - "org.qt-project.qt.audiosource" ' in the terminal. However, the microphone does work when placing phone calls, so the hardware must be hooked up somehow. Any ideas?
