I'm trying to play a WAV audio file with Qt (QSound, QSoundeffect) on an ARM based Atmel board (sama5d31ek).
I've build the rootfs (and Qt SDK for cross-compiling) with Yocto/poky.
When playing with QSound I get the following log message:
using null output device, none available
I'm getting nothing when running:
Qt Code:
  1. foreach (const QAudioDeviceInfo &deviceInfo, QAudioDeviceInfo::availableDevices(QAudio::AudioOutput))
  2. qDebug() << "Device name: " << deviceInfo.deviceName();
To copy to clipboard, switch view to plain text mode 

I can play the wile via command-line, with aplay (alsa).
pulseaudio util is missing.
