Public bug reported:
Binary package hint: arts
This happens on an Acer Aspire 3104 WLMi after upgrading from Gutsy to
Hardy (problem didn't exist in Gutsy) and has persisted thru all Hardy
updates so far.
At KDE session startup, not always but very often, and especially when
restoring at the same time a number of windows that would each produce a
little sound when opening, the system shows dreadfully slow and produces
no sound. It remains in this state of "dreadful slowness" indefinitely.
"top" then shows that several artsd processes (typically 2 or 3) are
running and competing for eating 100% CPU.
Issuing "killall -KILL artsd" (-TERM doesn't help) kills all mad artsd
processes and :
- The system suddenly issues a cascade of sounds that seems to have been
waiting, queued or whatever.
- After that a single artsd process is running, behaving OK and sound works.
Loaded sound modules are :

Sound hardware (per lshw) is :

Any clue ?
