    Hi,
    I tried to configure speech-dispatcher with ibmtts but i have
problems. when i started the speech-dispatcher i get an error from orca.
bellow is my ibmtts.log..

 Wed Nov 12 15:17:21 2008 [412451] ALSA ERROR: Cannot initialize Alsa device

In my speechd.conf i use alsa as my default audio output method  and in
alsadevice i put default.

    when i restarted my pc, speech dispatcher was worked well, but, the
other sounds events diden't work. i can not play music and other sounds.
    please help-me..
    thanks in advance,
paulo
