I would like to run pulseaudio on our custom board with dm365 processor
(arm926ej-s core). After some patching I have the sound running with alsa
utils - I can use aplay and arecord commands and they works.
I compiled pulseaudio 1.1 using buildroot. Now when I run pulseaudio
deamon I'm getting these warnings
W: [pulseaudio] main.c: This program is not intended to be run as root
(unless --system is specified).
W: [pulseaudio] server-lookup.c: Unable to contact D-Bus:

I do not have a X11 server on the board so I hope I can ignore these
Unfortunately when I try to use paplay command to play a wav file I hear
no sound and it also never ends and has to be killed. The log from aplay

Could please someone here give me some advice how to get pulseaudio
