Summary0002184: Audio stutters in 82.6.1 when affinity is set in singlethreated spring
DescriptionAudio randomly stutters very badly during the game.
Win7 x64, nvidia 8800gt, intel cpu.

Can provide audio sample on request.

Reproducibility is very strange: I first noticed it after manually setting spring cpu affinity to 1 core, because it usually smears itself over all 4.
If spring is set to 1 core, it stutters, if more, it doesnt.

None of my drivers or any system parameters changed from 82.5 to 82.6.1. This bug was not present in previous versions (for me).

There were no sound related changes between 0.82.5.1 and 0.82.6.1. :/

I have the same problem as he, but I have xp32, stutter when affinity is set, but for me it was also in 82.5. when using multithreaded spring bug disappears when MultiThreadSim=0, also in multithreaded spring the bug can also be seen when looking at Merl (actually all missile launching units) missile's exhaust, it stutters much like the sound.

the best way to make the bug is do give all with team 0 and give all with team 1 on top of it in single player

maybe this helps: http://springrts.com/wiki/FAQ:trouble#Sound (helped at least someone in the forum)

does the problem persists in 82.7.1 / did the hints in the faq help, if so, which one?

same thing in 82.7.1, the FAQ has no effect on my system, I think cause it happens only in spring and only when affinity is set to it

just an other idea: does it help to lower "Maximum simultaeouns sounds"?

(SpringSettings -> Mode->Advanced, ->Audio)

One side note: If the sound thread isn't getting CPU time frequently enough, it will stutter fore sure, and there is nothing else to do about it than to raise the priority of the sound thread, or reconfigure the audio buffer sizes in the sound driver. Typically higher end sound card use a very short buffer to give near instantaneous response. Some cards even stutter when you play a WAV file with windows media player (mine does).

Since this seems to not be the fault of the engine, I think this bug can be closed.
