I have no idea, judging from the artsshell output and that noatun appears in 
the Audio Manager it really should work. I.e. I've never seen something like

I'd like to know what those entries are. What multimedia programs do you use 
that could output to aRts?

Could be a hanging soundserver or a constant output from a program - but since 
you say noatun is sending sounds to artsd it should be moving.

Laptop suspend can do any undefined behavior to your system, so this is a yes. 
But most of the time it still works.

Didn't you say you had problems with the speed of the playback. Please try to 
use 48000 as sample rate - it might fix more problems than are obvious.

So you started it manually with debug output. Is there anything the debug 
output could tell?

If you know what process is holding a reference to the AudioMangerClient you 
can kill that process, but there's nothing artsd can do.
