Hi.
I am using QMediaPlayer with QMediaPlaylist to play short audio samples. Source code is here: https://github.com/Framstag/libosmscout/blob/master/libosmscout-client-qt/src/osmscout/InstalledVoicesModel.cpp#L138
It works fine, but when some music is played by Jolla Media Player, it is paused in the moment when start playing my samples… I tried to setup different audio roles, for example mediaPlayer->setAudioRole(QAudio::NotificationRole); but without success. Moreover, mediaPlayer->supportedAudioRoles(); gives me empty list.
I tried to search related pulseaudio features, but without success.

I tried to reproduce it with paplay with various properties, but without success too 
paplay -v --property=media.role=x-maemo --property=policy.group=player sample.ogg
It is possible to keep player playing, possibly just decrease volume for short time?
