[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:

#

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

Hello,

Thanks for your report!

So it complains that there is no user called "pulse". This is weird,
because in package/pulseaudio/pulseaudio.mk, we have:

ifeq ($(BR2_PACKAGE_PULSEAUDIO_DAEMON),y)
define PULSEAUDIO_USERS
        pulse -1 pulse -1 * /var/run/pulse - audio,pulse-access
endef

So, the pulse user should exist. Could you:

 - Check output/target/etc/passwd and see if a "pulse" user exists.

 - Make sure that this issue can be reproduced after doing a complete
   rebuild, i.e "make clean all".

Thanks!

Thomas

Hi Thomas,

thank you for your reply.

I try to set "BR2_PACKAGE_PULSEAUDIO_DAEMON".

# ps
...
  223 root     -sh
  224 root     /sbin/getty -L tty1 0 vt100
  256 pulse    pulseaudio --system --daemonize
  260 root     ps

it seen works in system mode, but I want to use "pactl" command.
I need set source and sink.

I get this error message:
# pactl stat
Connection failure: Access denied

#pactl list sources short
Connection failure: Access denied

#pactl list sink short
Connection failure: Access denied

Could you help me again.
Thank you very much.

Thanks, 
Jonas.

In case someone has the same issue. I got it working adding the root
user to the pulse-access group:

# grep pulse-access /etc/group
pulse-access:x:1006:pulse,root

@Thomas: Is this something we need to address if
BR2_PACKAGE_PULSEAUDIO_DAEMON is selected?

Best regards,
J?rg Krause

Do you have any idea how this solves the permission issue?

Not really. To be honest, I didn't really try to find a better
solution.
