[pulseaudio-discuss] Strange problem with pulseaudio 0.5.11

[Rafał Mużyło]

When I've seen the announce, I decided to see
it it works for me.
And for some strange reson it doesn't.

First, log messages of the failed run:
Jul 25 17:57:19 [pulseaudio] main.c: Found user 'pulse' (UID 107) and
group 'pulse' (GID 444).

Now, log messages of a 'successful' run:

What's the difference between those two ? The failed one was run as
--system.
Does somebody have an idea what's wrong ?
Hints about those front:0 warnings are welcome, too (I'm stereo only).
