Hi all,

I am trying to compile FG under Xubuntu 12.04 using Brisa's script (version 
1.31). At
first sight the compilation went fine, however sound is not working: when I run 
fgfs I
get the following error and no sound:

AL lib: oss.c:169: Could not open /dev/dsp: No such file or directory
Error: Audio device not available, trying default
AL lib: oss.c:169: Could not open /dev/dsp: No such file or directory
Error: Default Audio device not available.

(and indeed there is no /dev/dsp device on my machine).

A closer look at the compilation log
(http://www.mguillaud.net/fg/compilation_log_20120523.txt) reveals that PLIB 
fails
to compile due to some incompatibility with the OSS interface (the compilation 
script
does not stop, though).

Then I tried to build OSG, Simgear and FGFS against the PLIB version from the 
Ubuntu
repositories instead - same result. Compilation goes fine, but running fgfs with
"--show-sound-devices" produces the same errors as above, and then:

unknown provided by unknown
No. Device

What I find suspicious is that no sound devices at all are detected, although I
believe I have ALSA and Pulseaudio properly installed (including -dev packages).

Any clues about what is going on and how to further debug this ?

Maxime
