How do I stop the sound from echoing in Mame?
Timstuff:
I've got Mame running on my new PC that I built. Everything seems to be running very smoothly, except for one problem: the sound in games is always either on a delay, or it repeats itself and sounds messed up. My PC has a 2GHz processor and 512 MB of DDR ram, and as I said before, from a gameplay aspect, all the games run fine. But also, they all are on some kind of audio delay and/or repeating audio. Does anyone know what the problem is, and how I can fix it? Could it have something to do with the fact that I'm using Win 98 for my new PC's OS instead of XP, or does that not make any difference? I just wanna get the audio running the way it's supposed to.

If you are getting delayed sound, then simply change your audio delay settings within MAME.
If you are getting repeating or choppy sounds, your PC is too slow. MAME does not change the speed/pitch at which audio is played. What happens is if your PC is out of sync (ie: too slow) for the sound output, MAME stops the current audio stream and starts the particular sound again to try and sync it with the video. The end result is choppy or repeating sound.
You'll find this probably only happens on newer emulated hardware. On a 2GHz machine, almost all 3D games will have this problem, as will your more CPU intensive STV games. Care to list the games in particular that are giving you the audio troubles?
If you do desire to play emulated 3D games, I'd suggest switching to ZiNc instead.

I get dekayed audio with everything, including really old stuff like Galaxian. I get choppy/echoing audio on Mortal Kombat 2, Golden Tee Golf, and pretty much everything with more than 5 colors. I think I got choppy sound with galaxian once as well.

I tried running Mortal Kombat 2 in the oldest version of Mame I could find (version .69) instead of the sound immidiately being choppy and echoey, I got the same symptoms I got while trying to play Metal Slug with Mame32 version .81. The sound starts out clean, but on a delay, and then after about a minute or two of play it starts sounding garbly.
Although this would be a very bizzare solution to my problem, I wonder if my problems might have to do with my hard drive. It's the same hardrive I used on my slow-as-molassis 600mhz pentium 4, and I haven't re-formatted it yet. I think it's possible that my computer somehow thinks it's still a pentium 3. I think I should try reformatting the HDD and reinstalling windows and mame.

Also, mortal Kombat 3 seems to run alot slower in the newest version of Mame. And if I turn on auto frameskip, it becomes unplayably slow. But with version .69, it runs silky smooth, even when autoskip is turned on. I'm thinking I'm just gonna try reformatting the hard drive and see if that does anything.
