festival freezing the machine

[<fredm@chesf.gov.br>]

Hi,

Sorry by cross-posting. replyes should be send to festival-talk.

I'm trying to use festival in my machine:
pentium 4
sound:
      chipset i810
      model AC'97
OS: debian testing, kernel 2.4.22
festival instalation: apt-get install festival emacspeak eflite

My problem:

when I type (SayText "hello") festival says the text and my computer
freezes.

I try to create a .wav using text2wave and execute with xmms. and the
computer
plays the sound ok. but when I close xmms the computer freezes.

I try another .wav (a music) and that's ok with xmms. Note that
execute the .wav generated by text2wave don't freeze the machine
imediately. just when xmms closes.

I try Audio_Method = linux16audio
and Audio_Method = audio_Command as in
(http://www.cstr.ed.ac.uk/cgi-bin/lists.cgi?config=festival_faq&entry=arunning_festival/speed.html)

the .wav generadet by text2wave plays nice in windows XP.

when the computer freeze is not just keyboard and mouse. I try
shutdown -h +1 before SayText and nothing happens. I try to
ssh my machine after freezing and nothing happens too.

Is there any audio_method that I should try?
is there any config file that I should edit?
