[Interest] QAudioRecorder example produces only a buzzing sound

[Anisha Kaul]

I have a usb frame grabber with a microphone attachedto it.
I have tried to capture that device by VLC player to check whether it is
working or not. It works fine, I can hear the sound.

Following are the settings in the GUI of QAudioRecorder which I selected:
http://doc.qt.io/qt-5/qtmultimedia-multimedia-audiorecorder-example.html

I selected the output file with the extension .wav.
I selected in the GUI of QAudioRecorder: Line (3-USB Audio Device),
audio-pcm, audio-xwav, 44100, 2

The settings of VLC player were: Codec - PCM S16 LE (araw), Channels -
stereo, Sample rate - 44100, Bits per sample - 16

As we see that VLC codec info says *"araw"* and I have selected *"wav"* as
the container format.

Is that making a difference?

*What do I need to look in to find why am I getting only a buzzing sound
through QAudioRecorder but not through VLC player?*
