ok if i would renice the process:

renice [ufoai] -15

then the sound works fine in the game. but so i will get stutteringly menues.
maybe there is something wrong with the priority of the sound thread!?

for oss try this:
Code: [Select]

echo "ufo 0 0 direct" > /proc/asound/card0/pcm0p/oss


for sdl you can set the audiodriver via an environment var:
available drivers (may differ - depends on how sdl-libs are compiled by you or your vendor)
Code: [Select]

openbsd (OpenBSD)
dsp (OSS /dev/dsp: Linux, Solaris, BSD etc)
alsa (Linux)
audio (Unix style /dev/audio: SunOS, Solaris etc)
AL (Irix)
artsc (ARTS audio daemon)
esd (esound audio daemon)
nas (NAS audio daemon)
dma (OSS /dev/dsp, using DMA)
dsound (Win32 DirectX)
waveout (Win32 WaveOut)
baudio (BeOS)
sndmgr (MacOS SoundManager)
paud (AIX)
AHI (Amiga)


out this into your ufo-ai wrapper
Code: [Select]

export SDL_AUDIO_DRIVER [driver_from_list_above]

forgot about one thing: there is a second approach to implement alsa. rename the current snd_aksa.c in src/linux to and snd_alsa.c.tmp or somthing and then rename the snd_alsa.c.new to snd_alsa.c

i´ve not tested this driver for quit a long time - but maybe it will work for you - please give feedback,

i´m not sure whether it is compatible - i use the "old" xfree that ships with debian. why? doesn´t it compile? give me error messages, please

Yes, it is. I run it with Debian unstable.

Hey guys!!
First post, have to say: thank you so much for all that you are doing!!
This game is great!!
I have some coding skill but don't think good enough for actually working on the game code! Will try to help doing some "low skill" things... and reporting bugs, of course! :)

Now, something serious...
I'm experiencing the same problem with the ALSA sound driver: the .ogg are played at a ultrafast speed. Switching to SDL solve the problem. So, would say this is a low priority. I tried to use the snd_alsa.c.new but i couldn't compile:
.
.
.

ports/linux/snd_alsa.c:232: error: expected expression before '/' token
make[1]: *** [../debugi386/client/snd_alsa.o] Error 1
make: *** [build_debug] Error 2

So, I fixed all the comments from //comment to /*comment*/ and the true/false constants to qtrue/qfalse (in this case I just guessed... LOL, no idea about that!).
Anyway, I managed to compile it getting just a:
 * [UFO] ../debugi386/client/snd_alsa.o
ports/linux/snd_alsa.c: In function 'ALSA_SNDDMA_Init':
ports/linux/snd_alsa.c:103: warning: pointer targets in passing argument 3 of 'snd_pcm_hw_params_set_rate_near' differ in signedness
ports/linux/snd_alsa.c:118: warning: pointer targets in passing argument 3 of 'snd_pcm_hw_params_set_rate_near' differ in signedness

I think that this file needs more work as the alsa sound was wrong (guess the wrong things are going in the buffer) but I could hear the original music. The speed is better but is still faster than with SDL.

Hope all this will be useful.

Ops, forgot:
Version: trunk (just updated)
OS: linux debian unstable (kernel 2.6.16.20)

Keep up the good work!!
