I had flightgear operating very nicely until the latest ubuntu updates
(12.04 and 12.10). Since then I cannot get any sound.
I have traced it the cmake for openal not detecting alsa.
No matter what I try, cmake refuses to see alsa.
I am currently using 12.10. Any suggestions?

Hi.

Make sure you have the ALSA development packages installed (asound-dev
or asound2-dev or something, I think?). Make sure also to clear out the
build directory or delete CMakeCache.txt between tries, otherwise cmake
"remembers" it didn't find ALSA the first time.

If you do have them installed and it's still not finding it with a clean
cache, please provide the generated CMakeFiles/CMakeError.log.

As an aside: since you're on Ubuntu, unless you've disabled PulseAudio
you may want to consider making sure the PulseAudio backend gets enabled
too. If you're not using PulseAudio or don't mind using the
ALSA->PulseAudio bridge, you don't need to worry about it. But the
PulseAudio backend with 1.14 and newer does function a bit better when
using PulseAudio for sound.
