Linux client crash on some servers

[Gendeck]

Hi all. Im linux user and have a problem. When i try to connect to tammy servers ut crash always. I have to run ut with "padsp ut" and UT.ini settings I have "AudioDevice = Audio.GenericAudioSubsystem". With this configuration have sound in game and ts, no lag sound and all works perfect, but ut crash. I have tested in other servers and it works. Basicaly the error is:

I hope u find a solution to fix it.

Could you backtrace this error? (open ut-bin in gdb, run it, wait for the SIGSEGV then use the bt command in gdb)

strace output would also be useful.

Heh well, this doesn't really seem to be related to NPLoader... Have you checked if the error is always the same? Also, could you try to strace -o utlog -ff ./ut-bin -log and upload the output? Seems more like a corrupted .umx file to me.

[Gendeck]

I going to send u the log by email. 11 MB :eek:

[Gendeck]

Try here.. Finally i upload the file to megaupload

http://www.megaupload.com/?d=VBTGP0T3

Only crash on tammy servers. Sometime crash when loading map screen, and sometime when i can see the map while validating utpure, but always on tammy servers.. In other servers no have problems to play

[Gendeck]

There is an error. In post #3 i use gdb directly fron ut-bin and i need to run ut from my script (padsp ut). I run UT and i attach id under gdb. Shows:

Now i try to connect to Tammy server #2 and crash ut and:

I've never used gdb before and I've only been doing it this way.

What do u think about this AnthraX. Can be fix?

[AnthraX]

The log you sent me was incomplete. There should also be a log for the audio thread (which is causing the crash). You might have to sudo that strace command.

[~V~]

Linux client is very sensitive to correct audio formats in packages. If a server has a voicepack or such with the wrong format it will just crash it.

There is an alternative sound driver that doesn't crash but the sound is very low quality.

[Gendeck]

Sended all logs (9)

[AnthraX]

Seems that it's crashing because one of the sounds in Botpack.u is recorded at a frequency of 8000Hz. The audio driver you're using only supports 11025, 22050 or 44100Hz. The reason why it only happens on those servers is probably that the tammy servers use sounds that are not used on the other servers you visit. The easiest solution would probably be to patch Audio.so to support other sampling frequencies. Can't help you with that at this moment though. I'll add it to my todo list.

[Gendeck]

Thx a lot AnthraX. I will wait it =)

[~V~]

The easiest solution would probably be to patch Audio.so to support other sampling frequencies. Can't help you with that at this moment though. I'll add it to my todo list.

That would be great - looking forward to it.

[SoNY_scarface]

I'll say thanks even though I don't have this problem. Really appreciate the time and effort you put into UT Anth ;)

Huge kick but this problem started affecting me when I upgraded to Kubuntu 11.10 and I'm looking for a fix.

The problem is that the more recent Ubuntu versions don't support OSS (the old sounddriver UT uses) anymore and you don't have sound when you start it:
Bound to ALAudio.so
open /dev/dsp: No such file or directory
Audio initialization failed.
When using ALAudio.ALAudioSubsystem

Bound to Audio.so
Failed to open audio device.
Audio initialization failed.
When using Audio.GenericAudioSubsystem

This can be fixed by using padsp (http://linux.die.net/man/1/padsp) which redirects the output to PulseAudio, yet with the standard audiodriver (ALAudio.ALAudioSubsystem) the sound lags half a second. This then can be fixed by switching to the generic driver (Audio.GenericAudioSubsystem) by changing [Engine.Engine] AudioDevice in UnrealTournament.ini

# AudioDevice=ALAudio.ALAudioSubsystem
AudioDevice=Audio.GenericAudioSubsystem

Using the Generic audio driver however generates the bug described above on some maps/servers but at least you can play with good sound on some of them. Using AlAudio doesn't give this bug.

The solution would be to
1) Fix the lag with ALAudioSubsystem / padsp
2) Add support for additional rates in GenericAudioSubsytem
3) Renable oss

I know someone tried (3) but failed, I have no clue on where to start with (1) or (2) and don't know if there's any sources of ALAudio0.0 or Generic around and how the internals of these and the libraries work. Does anyone have some clues?
