I have a machine here where I did the upgrade from Fedora 10 to Fedora 11
and I see similar symptoms to what you report in your FC10->FC12 upgrade.
For the most part, all other audio apps are just fine on this machine. I
can play youtube videos, I can play mp3's and audio CD's. I hear the
desktop sound effects, etc. But audio for FlightGear has been totally hosed
since my upgrade.
I have another machine (laptop) which I installed FC11 directly, and audio
with respect to FlightGear is better. I generally hear what I should here,
but there is quite a bit of static/crackling mixed in, so it is far from
perfect.
Erik mentioned running openal-info or alcinfo, but neither of these are
installed on my machine with my version of openal or alc:
$ rpm -aq openal
openal-0.0.9-0.17.20060204cvs.fc11.i586
As others have pointed out, pulseaudio (despite it's imperfections) is
installed by default on a lot of current distributions. It seems like we
should try to find a way to work with it some how. I personally don't want
to uninstall pulseaudio from my system and then have to struggle with all my
other individual apps to reconfigure their audio and get them back to a
working state ... right now, FlightGear seems to be the only app I have that
isn't playing nice with pulseaudio.
Even my virtual machine (windows XP running inside my Linux host) happily
plays all it's sound effects through my linux host system.
Regards,
Curt.
