Description
This may be a duplicate of a closed bug:
https://bugreports.qt-project.org/browse/QTBUG-10729
We compile Qt with ALSA support, but no PulseAudio.
Our program was hanging when playing audio. It appears that QAlsaAudioOutput::stop() can hang in the call to "snd_pcm_drain(handle)".
The attached sample program hangs within a few seconds on Ubuntu 12.04 (32 or 64 bit) and Ubuntu 14.04 (64-bit).
