Loosing Realtime Playback With Sound On

[uiron]

hi,

i got a problem when animating with sound turned on. When i loop through scene a couple of times (and, when synching, you got to go back and forth a lot), i'm starting to loose FPS, it feels like maya gets jammed or something.

To exclude all other problems (slow rig or other scene issues), i tested on a empty scene, with just a sound imported.

First time it plays smoothly. If you let it loop couple of times, or even worse, stop animation, move time slider back and play from there, maya starts skipping frames, just like if you had a heavy scene which cannot be played back in real time. if i save the file and play again, it's smooth again. couple of playback loops - the same problem again.

there's no problem with sound itself, it's just that i can't get scene to keep up with the sound, which in lipsync situation is very big problem - i need realtime playback at all times.

i already tried turning off history, undo stack, different .wav bitrates... nothing helped. if i turn sound off, playback is fine, so it's definitely sound problem.

What version of maya? Have you reprotted autodesk with your machine specs. I for one can not replliacte the problem. Try different sound driver. As it deifnitely sounds like the driver of your soundcard is having some problems (also try unchekking any dsp effects you may have on in the soundrivers settings, often some are on by default)

This is off course a bit expected since the general weakest point in most computers is the bus now since the sound and the gfx card work out possibly on the same pipe it means they directly compete with each other so any baed vulnerabilities or flaws in dirvers and data amounts accumulate.* Also often this day and age the sound chips are amllmost of no use they just load the cpu for their effects if of cheap quality wich needles to say can be a game baker.

Do what you do for heavy scenes playblast all the time.

• yes this is a HUGE issue, the cpus get faster and faster but their communication channels do not actually get any much faster so one is in situation where the bus is the more limiting factor than the rest of the setup. Which is why choosing the right motherboard is more important than ANY other single thing on the computer.
