I want to play some music on the device(IMX6), So I use QSound of Qt 5.6.2 to make a test project.
First, I got the debug : pa_context_connect() failed. So I use "pulseaudio -vvvv --system" to check it (cus this is an embedded device). It circulate in :
D: [pulseaudio] module-udev-detect.c: /dev/snd/controlC0 is accessible: yes
D: [pulseaudio] module-udev-detect.c: Resuming all sinks and sources of card alsa_card.platform-sound.
I have no idea about that whether it works or not. So I quit and "pulseaudio -D --system", it works.
However, there is no voice after that by using mplayer/paplay/Qt-QSound. More importantly, the output of paplay is:
Opening a playback stream with sample specification 's16le 1ch 8000Hz' and channel map 'mono'.
Connection failure: Access denied
What should I do?
Regards
Mihan
