Description
Application crashing when audio is used, It doesn't matter if QSound or QSoundEffect is used it always crashing for ios. Same works for android. It's crashing mainly when we use more intensive playing sounds (very short sound).
Attached simple example where playing many sounds in short time and after short time (often less than 1 minute) code crashing. Always in the same place CoreAudioOutput::audioDeviceIdle() AURemoteIO::IOThread EXC_BREAKPOINT
Run this code on iphone or ipad and keep it running for few minutes to observe the crash with following stack:
