common problem with SOUND SHUDDERING!!

[Rustynutts]

Hi all, i have come across a common problem witch seem's to pop up every now and then.

Whith sound suddering in mame. Now my pc that WAS running the cab was showing its age, so I built

A new pc with dule core duo E6420 cpu and a ATI Agp X1600, 2 gig ram,sound blaster PCI card.

Now i have a high end gaming rig in the other room that i test all mame related stuff on.

i can have every thing on ie (vert sink) (tripple buffer) you no all the bells and wissles. no problem

shonobi runs no probs on that pc ( no shuddering) shonobi is a good one to test as sound shuddering start at the first screen.

got the cab up and running with my new pc installed up to date thinking it would have no probs at all.

RONG!!

STILL HAD BLUDDY SHUDDERING I V-sink was enabled switch of the V-sink & tripple buffer & sink to monitor refresh all that stuff . It ran fine then but I was no better of with the pc I had. So

pissed of i got the gamming rig and put in the cab same problem SUDDERING SOUND!!!!!

It worked when it was rigged to a PC monitor.

Problem being ITS THE BLUDDY TV OUT ON THE GRAPHICS CARDS!!! It will not sink to a TV!!

Try using the -d3d option in Mame command line settings. You may experience stuttering using the old -dd option (Direct Draw). I had that sound stutter problem on my fairly decent machine.

Hi headkaze, i'v tryed every thing but found that if you use the TV out on an ATI Graphics card it will not sink properly to the TV tryed on two different PC's useing an X1600 and an X1900pro both useing

dule core duo's. They sink spot on when useing a standard PC monitor funny thing is It only affects

Mame, that I no of I'm useing mame32pluss 116. Its a shame because when I was re-building the Cab playin on MAME in on the PC in the other room with V-sink on it was easy on the eye.

Thanks for your response Headkaze I no your a busy man

Oh I didn't know what your were saying when you said "sink". V-sink made me realise you were talking about vsync.

TV's are generally stuck at 60 Hz refresh rate, so setting vsync on a TV is probably not a good option. But of course there may be an issue of tearing.

The reason VSync can effect the sound is because if you have the refresh rate of your output device (in this case your TV) set to 60Hz and you turn on vsync, then without frame skipping emulation may have trouble updating in that 60Hz range. I would turn off "Sync to monitor refresh" and "Wait for vertical sync" in Mame. I would also set to Direct3d instead of Direct Draw.

I've always had greater CPU headroom with DD vs D3D. However, if this is a hardware issue (TV), then you might need powerstrip or google 'refresh force'. TV's require encoding; and the reason a PC monitor automatically syncs is cos of appropriate drivers inherent in Windows.

I am having problems with sound studdering too. Even something as simple as pac man is giving problems. I have a 2.0Ghz machine so I'm not sure what the problem is. What options in the command line are you guys using to fix this? Does the command line stuff go under "Advance MAME Settings" ?? Thanks.

to get rid of the sound shudder I set mame32pluss up to have tripple buffer no vsink but make sure you set frame skipp to 2/12 it sorted my problem out.

I no longer get screen tearing or sound shudder.

hope that helps m8.
