Hello, I hope it is good place for my request. I am looking for some
tips to configure the pulseaudio server on an embedded system. The
program is in the system, but I have difficult to lauch it correctly.
After setting
DBUS_SESSION_BUS_ADDRESS=unix:path=/var/run/dbus/system_bus_socket and
DBUS_SESSION_BUS_PID=`cat /var/run/dbus/pid`
Why do you do that? It's not exactly a surprise that things break if you
make PulseAudio connect to the system bus when PulseAudio expects a
session bus.
I understand now it was not a logical try.
Maybe I can start from the beginning if someone can respond to me.
So I am using Open Embedded daisy without X11, PulseAudio 5.0, Linux
armv5tejl 2.6.37.6 #18 PREEMPT.

Aplay works correctly from root but not from an other user (I should do
setup of the sound card).
From root :
pulseaudio --system met the error shm.c: mmap() failed: Cannot allocate
memory
Does this error prevent pulseaudio from starting? What's the output of
"pulseaudio --system -vvv --log-meta"?
Yes, pulseaudio is not running after that. See attached complete log.
E: [pulseaudio] shm.c: mmap() failed: Cannot allocate memory
E: [pulseaudio] core.c: pa_mempool_new() failed.
E: [pulseaudio] main.c: pa_core_new() failed.
Is it the usual way in embedded to launch from root with --system mode ?
