Karsten: Thanks for the response:
1) Downloaded OpenAL from the web site. I'll check my own cd's as well.
2) Configure showed no error messages when installing OpenAL. Only alut
has this problem (tried to make this from the alut dir as instructed). Is
alut required for sound to work? If not, I won't bother trying to fix it.
3) .openalrc file now looks as you described. The only difference is
that I'm forced to use sound card "1" instead of sound card "0", due to
other problems, so I've changed "hw:0,0" to "hw:1,0". Is this the correct
syntax?
Thanks,
Steve

Hi Stephen,

Hi: FG graphics/joystick work fine on my Linux FC4 system, but no sound.
I've been working on this problem for weeks, with no success. My system
uses ALSA, and am able to get the "ordinary" Linux event sounds to work
OK
(opening, closing windows etc). I can also put "test" sounds (.wav) files
through the system OK.
1) OpenAL installed OK, but but not the alut portion. It says missing
references in the hello_world.c file. Trying to follow the procedure in
the
README file, but no luck so far. Is alut required in order to provide
sound
in FlightGear?
You are using Fedora Core. Did you tried using the rpms befor baking your
own
openAL?
2) So far, the only executable binary found under openal is
"openal-configure". Is this correct? I would have expected something like
"OpenAL" to start the application.
openAL is just a library as the libc. The only purpose it has, is
including
openAL into other Application to have sound. The app "openal-configure"
you
mentioned, is for autotools/autoconf. You, as a person, do not need them
at
all, to run anything having openAL support enabled.
3) The docs say that I should have a ".openalrc" file, which requires an
added statement, but all I can find is "sample.openalrc". I've since
created the file, with only one line, as stated in the FlightGear
README.sound file. I've put this file in both my home dir and under
/...FlightGear/data, no change.
Correct, you need a file called ".openalrc" in your /home/stephan. It
needs to
have a dot in the beginning.
What about writing down here the content you have in your .openalrc?
I assume your configuration will look like this:
(define devices '(native alsa sdl esd arts null))
If you look some lines down in README.sound, you'll see how to use ALSA.
Better you first try a 2.0 sound config:
(define devices '(alsa))
(define speaker-num 2)
(define alsa-out-device "hw:0,0")
4) I've studied and attempted to fix the problem, but my experience is
limited: Used to Linux, but only know a little "C".
I doubt that you have to fix something regarding the source of openal. :)
It would seem that I'm still missing something, don't know how to start
OpenAL or still need alut. If I had some idea of where to look, I could
at
least investigate before "dumping" the numerous files required for a pro
to
analyze it.
Better you simply do it. Do you compile FGFS at your own? Does the
configure
command complain about a missing alut-lib?
