Hi Erik,
Again, thank you for taking the time to reply...
>> line 'int error = alutGetError();' should clear
>> any error for the next call.
Yes, but that call is done AFTER the WAV load, but
taking your idea, and the fact that the previous
error message does state 'already' an error,
applied the following small patch - added 5 lines :-

Then fgfs ran fine, with simple sounds, with the
console output :-
~/fg/fg7$ ./run_fgfs.sh
run_fgfs.sh: Running: ./fgfs --fg-root=/home/geoff/fg/fg7/fgfs/data &

ALC Error (sound manager): ALC_INVALID_DEVICE at
load: /home/geoff/fg/fg7/fgfs/data/Sounds/rumble.wav
PNG lib warning : Incomplete compressed datastream in iCCP chunk
PNG lib warning : Profile size field missing from iCCP chunk
power up
So it seems this ALC error is further back in the code,
and is not checked and cleared until 'load' is reached...
And once cleared by my patch, the wav load proceeds, and
fgfs _FLIES_ ;=))
As indicated, I have libalut0 and -dev 1.1.0-1 only
installed, through the Ubuntu Package Manager,
and have NOT tried building, and using FreeALUT,
OpenAL-Sample nor OpenAL-Soft in Ubuntu.
And as previously reported, when I run fgfs with the
show 'device' option, I get a 'blank' for device 0, and
"weird vorbid_get\n" for device 1, as per :-
~/fg/fg7$ ./run_fgfs.sh --show-sound-devices
run_fgfs.sh: Running: ./fgfs --fg-root=/home/geoff/fg/fg7/fgfs/data
--show-sound-devices &
~/fg/fg7$ Software provided by OpenAL Community
No. Device
0. ""
1. "weird vorbid_get
"
When I open my Ubuntu 8.04 LTS System -> Preferences -> Sound
my 'Sound Preferences' dialog shows as follows, with the
results when I selected and tested each with the [Test]
button :-
Tab: Devices
Sound Events
Sound playback: Autodetect (selected)
Options:
Autodetect - test tone works
STAC92xx Digital - test failed, nothing
STAC92xx Analog - test tone works
ATI HDMI - test failed, nothing
ALSA - Advanced Linux Sound Architecture - works
OSS - Open Sound System - test tone works
PulseAudio Sound Server - test tone works
Music and Movies:
Sound playback: Autodetect (selected)
Options: as above list

Options:
STAC92xx Analog, ALSA, OSS, PulseAudio,
Test sound, Silence
Default Mixer Tracks
Device: HDA Intel (Also mixer) - selected
Options: Similar list to the above.
And no rush, now that I have fgfs up and
running with my above patch ;=)).
HTH
Regards,
Geoff.
PS: Still the strange PNG warnings, per console...
