Comment:

 Hallo Lennart.

 In fc12 problem comes back unfortunatelly.
 eflite deamon thread gets stuck in following stack trace:

 all packages, except eflite come from fc12 distribution. Especially I run:
 $ rpm -qi pulseaudio
 Name        : pulseaudio                   Relocations: (not relocatable)
 Version     : 0.9.19                            Vendor: Fedora Project
 Release     : 2.fc12                        Build Date: Wed 04 Nov 2009
 09:16:58 PM CET
 Install Date: Mon 09 Nov 2009 06:02:57 AM CET      Build Host:
 x86-1.fedora.phx.redhat.com
 Group       : System Environment/Daemons    Source RPM:
 pulseaudio-0.9.19-2.fc12.src.rpm

 Below is detailed instruction on how I reproduce the problem:

 prompt# yum install emacs emacspeak flite flite-devel alsa-lib-devel
 edit /usr/bin/emacspeak (> - add; < - remove):
 ....
 ....

 > export DTK_PROGRAM=/usr/src/eflite-cvs/eflite/eflite

 EMACS_UNIBYTE=1
 export EMACS_UNIBYTE
 < exec emacs -q -l /usr/share/emacs/site-lisp/emacspeak/lisp/emacspeak-
 setup.el $INITSTR $CL_ALL
 > exec emacs --eval '(setq dtk-quiet t)' -q -l /usr/share/emacs/site-
 lisp/emacspeak /lisp/emacspeak-setup.el $INITSTR $CL_ALL

 --- end of /usr/bin/emacspeak file.

 "--eval '(setq dtk-quiet t)'" is added to defer initialization of speech
 server so that one could attach debugger before eflite gets stuck.

 prompt# mkdir /usr/src/eflite-cvs
 prompt# cd /usr/src/eflite-cvs
 prompt# export
 CVSROOT=:pserver:anonymous at eflite.cvs.sourceforge.net:/cvsroot/eflite
 prompt# cvs get eflite
 prompt# cd eflite
 edit Makefile:
 < CFLAGS   = -g -O2 -Wall
 > CFLAGS   = -g -O0 -Wall

 < #CFLAGS+= -DDEBUG=2
 > CFLAGS+= -DDEBUG=2

 -- end of Makefile
 "-DDEBUG=2" turns on putting information to ~/es.log

 prompt# ./configure --with-audio=alsa
 prompt# make

 to test if it works fine:
 login-user-prompt$ ./eflite
 q { hello }
 d
 login-user-prompt$

 You should hear "hello".

 This is all about compiling. Now I'll write how to reproduce an error.

 login-user-prompt$ /usr/src/eflite-cvs/eflite/eflite -D
 Please attach with GDB to this process and let it run.

 "eflite -D" command creates daemon process (the one that gets stuck).
 It will also create socket:
 login-user-prompt$ ll /tmp/es.socket
 srw-rw-rw-. 1 me group 0 2009-11-23 22:00 /tmp/es.socket

 this socket is used to pass request by eflite client process (issued by
 emacspeak).

 login-user-prompt$ /usr/bin/emacspeak

 emacs will start eflite client process. YOu will see new "eflite" process
 in "ps xauwwwuf". Because I added "--eval '(setq dtk-quiet t)'" to
 /usr/bin/emacspeak, it will not start talking immediatelly.

 While in emacs put:
 Ctrl-u Esc-x dtk-toggle-quiet <Enter>

 this command will enable speech. You will probably hear some words, which
 is ok.
 Now try to type some words. 2 or 3 characters will probably be spoken but
 that's all! eflite deamon gets stuck. Please stop eflite daemon in GDB and
 issue "bt" command.

 That's all what I was able to do with this problem. I am of course willing
 to help.

 Because using pulseaudio 0.9.19 didn't help I decided to rewrite defect
 back to You. I hope I didn't do the mistake.

 Best regards,
 Michal.
