Repeating audio

[toasty]

When I play some games -- Tempest is a noteable example -- the audio will sometimes repeat itself.  For example, when I shoot something, I will hear it explode twice in quick succession. 

Anyone else have this problem?

I'm running mame v1.02.  I'm running it through MAMEWAH, but it also seems to do it when running it through MAME32.

Thoughts?

Do you have vsync or triple buffering turned on?  I noticed that would garble the sound in most games for me.

I'm not sure, but I would say no unless that is a default setting, b/c I haven't tweaked the audio on my computer or in MAME at all...

I'll have to take a look when I get home and am in front of my MAME system...

I had this same annoying problem.

Could you post your PC specs, for a comparison?
Here's my specs from the PC that had the problem:
Compaq Presario
Processor: 450MHz AMD K6-2
Memory: 312Mb (128 stick, 128 stick, and a semi working 64 stick
Chipset: SIS Sinbad
Installed a new soundblaster card

You can try cutting the audio sampling rate (In MAME32).
Also you can try running an older version of mame.

^^ I think I have plenty of juice, by MAME standards:

e-machines
Athlon 2200
512 MB RAM

BTW, regarding an earlier post, neither vsync nor triple buffering were on.

I've had this problem in the past and solved it by scaling the screen resolution down.

I had audio problems with DirectX enabled. Tried Tripple Buffering on/off, V-sync on/off, samplerates, priority, the only thing that cured it on mine was DirectX disabled which sucks if you want to play pacman or galaga on a horizontal monitor!
My cab has a Sempron 2800, 256MB RAM, ArcadeVGA 7000 the only thing I didn't try wich i suspect may be causing the problem is crummy onboard sound

I think this is a known bug. I only know of a fix in Mame32 though. Go to Options->Default Game Options->Miscellaneous tab then take off the tick from "Use RDTSC timing system".
