 I reiterate that chez moi, the festival features as
 documented in Docs/getstart.pdf do not work.  They
 have not worked for years, if ever.  This bug has been
 observed using Debian Etch, Debian Lenny, and now Debian
 Squeeze.

 In every case, I observe that the festival server works
 fine when FGFS is not running, but is unable to make any
 sound when FGFS is running.  This is unsurprising, given
 that both of them are trying to send to /dev/dsp which
 AFAICT has never allowed multiple access.

Well, that you have not configured your sound system correctly isn't 
really FlightGear's fault, is it?

Of course, the documentation could match your system better than it does, 
but Linux sound is pretty diverse and changes over time. The wiki might 
contain something about systems closer to yours.


I have Debian/testing and use ALSA for sound (default for my installation).

1. I configured OpenAL to use ALSA:
(If you have OpenAL-soft you might find more info in 
/etc/openal/alsoft.conf)

and...@sleipner:~$ cat ~/.alsoftrc
format = AL_FORMAT_STEREO16
cf_level = 2
drivers = alsa
[alsa]  # ALSA backend stuff
device = plug:dmix
capture = plug:dsnoop

2. I don't remeber if I had to touch the festival config or not, but here 
it is:

and...@sleipner:/etc$ cat /etc/festival.scm
(Parameter.set 'Audio_Command aplay -D plug:dmix -q -c 1 -t raw -f s16 -r 
$SR $FILE)
(Parameter.set 'Audio_Method 'Audio_Command)
(Parameter.set 'Audio_Required_Format 'snd)

3. I set /sim/sound/voices/enabled to true in my ~/.fgfs/preferences.xml 
file (included via .fgfsrc).

 Setting up a .openalrc file as mentioned in README.sound
 does not solve the problem.

One possibility is that you have OpenAL-soft which uses .alsoftrc 
with a different syntax instead. (IIRC it does complain if it finds a 
.openal, though).

I hope this helps.

Cheers,

Anders

Festival has worked with FG for me , too , but I haven't set it up
recently...
I do remember having to tweak the the .openalrc file a bit ...
Maybe I'll try it agian with openal-soft and see what happens.

Ive just installed festival with 2 voices , started festival --server  , and
I hear all the MP messages . No configuring of any files was required .
Now if festival voices were just a little clearer :).
