Hi,

Why does the process »pulseaudio« always consume processing time?
On a computer of Centrino class about 2% (varying) of the CPU processing
time.  This is true although I do not play any audio file. 

Is pulseaudio a rather communicative process which challenges a CPU of
medium processing power rather much?
Who talks pulseaudio to all the time?

'~$ sudo strace -p [PID of pulseaudio] > /path-to-file
2> /path to error message file'
-->
'~$ sudo strace -p 1338 > ~/tmp/pulseaudio.log
2>/tmp/pulseaudioerrors.log'
obtains in the first file 0 bytes contens and in der 2nd file
http://pastebin.com/mG6bDuX1 

What can I learn from this 2nd file's content?

Regards,
Detlef
