[Buildroot] pulseaudio isn't work on buildroot-2017.02.5

[Jonas]

Hi,

I'm useing RPi and buildroot-2017.02.5.tar.gz.
linux is work but pulseaudio is not work.

The following is my config:

System configuration  --->
/dev management (Dynamic using devtmpfs + mdev)  --->
Dynamic using devtmpfs + mdev

Toolchain  --->
Enable WCHAR support 

Target packages  --->
Audio and video applications  ---> 
pulseaudio

Target packages  --->
Audio and video applications  ---> 
alsa-utils


The following is error message:

#
# modprobe snd_bcm2835
#
# ls /dev/snd/
controlC0  pcmC0D0p   pcmC0D1p   timer
#
# aplay -l

I don't know how to solve this issue
how to let pulseaudio process work.
