Description Luke Hutchison 2005-10-03 18:52:32 UTC 
With Evolution set up to play a .wav file when new mail arrives, after a random
number of weeks' use, Evolution starts to lock up every time a sound is played,
with the following backtrace.  Firefox also locks up from this point on,
whenever the Flash plugin is trying to play a sound.  Both use esd:

The only solution to this problem is to delete the ~/.esd_auth file, and restart
esd.  My file currently contains:

$ hexdump .esd_auth
0000000 6e01 0a1a 7add 969d 8f20 2c1f 3efe 8f33
0000010

Rebooting the machine doesn't do anything if you don't delete the .esd_auth
file.

This appears to be a case of a stale lockfile left around.  Is there anything
that can be done about this?  It makes some apps unusable, and is very hard to
figure out how to fix.
Comment 1 David Schleef 2005-10-03 19:05:45 UTC 
Is esound running at the time of the lockup?
Comment 2 Luke Hutchison 2005-10-03 20:42:29 UTC 
Yes, sorry, I should have said that esd has to be killed as well as the auth
file deleted.
Comment 3 Luke Hutchison 2005-11-17 03:57:36 UTC 
I have found this is fairly easy to duplicate -- if the Flash plugin is playing
sound when Evolution tries to play a "new message" alert, it causes the lockup.
Comment 4 Jeffrey Stedfast 2008-07-10 23:30:12 UTC 
my patch for bug #542391 should solve this hang
Comment 5 André Klapper 2012-02-28 20:33:15 UTC 
"esound" has not seen code changes for more than three years according to http://git.gnome.org/browse/esound/log/ , and it will not see further active development anymore according to its developers.

Closing this report as WONTFIX - Please feel free to reopen this bug report in
the future if anyone takes the responsibility for active development again.
