Summary0000822: More sound & crash problems (OS X, 3.901)
DescriptionAfter taking 3.901 I hoped it would be solved, but again I get the problem where sounds (except music) stop playing, and the game crashes a short while later. Now it crashes to the desktop instead of freezing the PC.

One more detail I forgot to mention:

when the sounds stopped playing I tried to "power cycle" the sounds by going to settings and turning sound + music both off, returning to the game, then going back to re-enable them. The crash happened shortly after re-enabling the sound.

I've put in a change in 3.902 that will hopefully help, or possibly resolve this. However, if you do see this again, when the sound cuts out can you try disabling the sound real quick and see if you can then avoid a crash? That would be useful info, though this is a frustratingly quirky issue.

hi, did just what you suggested x4000. As soon as the sounds were gone i disabled both sound and music. No crash. As soon as I enabled both again (ca 10 min later) it crashed.
Here are the last lines of the player log: (version 3.903)

Awesome, that's really encouraging actually. It's a shame that this is happening still, but at least it's isolated to what it is now! That part is exciting. :)

We'll see what we can find on this...

I wonder if we could put in code that, when it detects the exception in the sound code, it sets a flag that early-outs of all such sound calls for the rest of the app execution?

This would just be for debug purposes but perhaps a toggle on the audio tab of the settings window or a entered-into-the-chat-window command.

To be clear, we could add a check in LogWritten that if it sees "pthread_getschedparam" in the message it sets that no-sound flag.

That last error from 3.904 is actually scary. What it's saying is that AI War died on trying to load an image, there. In other words, that once the game passes a certain number of sounds/images needing to be loaded, it's killing them all.

And that... I think I should be able to fix that.

Okay, for the 3.905 version, which will be out in a little while:

* The game is now strictly limited to 12 open disk threads at a time. Previously it would usually be that few or fewer, anyway, but in a few cases it could get higher and this could lead to jerkiness on windows and potentially crashes on OSX.


Hopefully this will solve your problem. In my tests, I rarely even saw 12 open disk threads, even during big battles with a lot of sound effects streaming off the disk, but it was definitely possible for a confluence of events to make it reach all the way up to the 16 count that I believe would cause this on OSX.

If you still see this in 3.905, then I'll make this configurable so that you can set some lower values to see if that works instead. But this should be enough protection room between there.

Same deal as before, if you hear your sound cut out can you please disable sound and see what happens? But also, this time if you can hit F3, and then look down to the very next to last line where it shows the music, there is now a Disk Threads Count. I'd like to know what that says, if you run into this again. It could be that some sound threads are having a silent exception and aren't properly cleaning themselves up, and this would tell us that.

However, if that IS the case, then actually your sound would probably cut out, and no more images would load, and the music would stop after the next track and wouldn't continue, but the game wouldn't crash. That's what I expect, anyway.

Should be interesting to see what this does, it really feels like we're getting closer, at least! Thanks again to all the patient OSX folks for their help on this. :)

Tried again this morning. Heres what happened: Version 3.905
(I didn't switch off sound or music)
1. Sound effects gone music still playing
2. Music gone as well
3. Sounds is on and off and on again
4. after a couple of minutes Crash.

Maybe this is connected: After the sound effects were gone some of the buttons were gone, like the whole build turret tab was empty, some other buttons were still there. Also I was unable to place some of the turrets.

Had another crash later, however this time there was no sign for it (sound and/or music gone) before it happened. So there was no time to switch off the music or sounds.
However the Debug line for the music (F3) says:
Current Music Track / Number Disk Threads :/Expansions/1/Music/Ingame/Heart of Zenith / 4

Hmmm...

I just can't duplicate this. Can anyone else at this stage? I'm starting to suspect there might be some sort of sound driver or similar on your machine at this stage, especially with only four disk threads open (and nothing suspicious in any of the logs you posted). Have you made sure that your drivers are all up to date?

At this stage, without more information, I'm kind of out of ideas on what to do. The way that it was happening in your last post really seems odd.

I think the drivers should be ok, this may sound stupid but how can I check this on a Mac?
Of course theres always a chance that it's my system that is causing the crashes, lets wait and see whether there are others with the same issues.
I'll just switch to the windows Version and test again as soon as new updates are released.

Cheers cyrill

tbh, I'm not sure how to check those on a mac. I know that a lot of the driver updates come out through the apple updater itself, and I haven't looked beyond that. Again, sorry for the trouble here.

Thanks for letting us know about it happening again and for the log file. I went through the log and didn't find any really new info.

I've never been able to get much info on the pthread_getschedparam thing, so I don't know if it's an actual threading issue or if it's just a symptom of something totally unrelated going wrong in our code.

I have the same issue, version 4.021

I also tried to disable-enable, first music then sound, after that the game crashed and brought me to the desktop.

Before crashing but after the sound muting it also showed some more glitches, like being unable to see full zoom models of some ship types and just not showing the markV ships that can be made in the tutorial campaign.

Where do I find my error reports? I'd like to help somehow.

The error reports would be under your RuntimeData folder in the game folder. The toggling on/off sound/music really wouldn't have much benefit I don't think. We have some stuff coming in the next release that might solve this problem, but we've thought that before, too. I still have yet to ever be able to duplicate it on my Mac! Very odd that it strikes some folks and not others. Anyway, I feel like we're narrowing down a lot of the issues at least, so hopefully one of these fixes coming up will do it.

Okay, a new version 4.022 is now out. Either hopefully that would solve it (ideally), or hopefully it will make it easier for us to track down, at worst. Or, at worst, I guess hopefully it eliminates yet one more suspect. Thanks for your patience and your help with this one!

Coming in 4.023:

* If the dreaded pthread_getschedparam error is encountered on OSX, normally this means a crash is imminent within 30 seconds or so if the player does not disable their sound first.
** We've been attempting many things to solve this problem, and still will be hunting for it, but as a temporary salve we've now made it so that when this error is encountered it will AUTOMATICALLY disable the sound for the player and shows them a message advising them to save their game and restart the program asap.
** It also now logs some extra information about the state of their program to hopefully aid in actually fixing the root cause of this.
** It also stops further images, music, and similar from being loaded, as they could also trigger the same crash and the player really needs to restart, anyway.

 OK, with 4.025 I got the warning message and the sound turned off automatically, so I quit the game safely. You said there were extra logs for this? Where can I find them? I don't want to restart the game because I know some things get cleared when one starts a new session...

Just all the .txt error logs in your RuntimeData directory. I don't think Chris added any new logs for this, just made the messages more informative for us.

Thanks!

Thankfully, it seems that Chris's rewrite of the sound subsystem has finally solved the OSX saga of problems with it :)
