Author Topic: Mame32 and Sound... (Read 3094 times)

This may sound dumb but I don't have an actual soundcard in my PC. Its one of those onboard things. Some games have sound cracking at times and I'd like to know if a separate soundcard will eliminate this problem. Everything else runs perfectly, just my sound sucks.

Is this a relatively modern MB? I use the on-board sound off a fairly new MB (AMD KT-333) and it at first sucked in the same way. I was able to fix it though. Somewhere either in the Sounds section under Control Panel or the MB manufacturer's provided sound utilities there were some quality settings. I really had to dig for it though, but when I found it I just upped a setting and it fixed all the sound chopiness.

But yeah, a separate sound card would solve that problem. I have a slower computer with a sound card and it never had the problems my on-board one experienced. Though definately poke around looking for settings on the on-board one.

My on board sound in games used to cut out when the game was taxing the system on my 98 box. When I installed XP on the same hardware the sound no longer cut out in the same games. The on board sound was what is bundled with most VIA chipset the 98 Codec I think.
I finally broke down and bought a SB live from Newegg and have never been happier with the sound in games.

Yeah it's a newer MB. It's a Gigabyte P4 Titan. I checked but was unable to find the settings mentioned. Oh well.

Thanks for the nfo

I have the same problem on mine. I'm running WinXP. My cab is running the DOS version, so I don't really worry about it, but I thought it was a bit odd that it keeps cracking and sometimes repeating music and sound FX. My MB is older - ASUS P2B but it's running a SB Audigy. Odd.

Yeah, integrated sound cards off load the sound processing to your CPU,where separate sound cards do there processing internally and don't dog your cpu.
Turn on the frame rate counter in mame I think you will see
the frame rate go way down when you are experiencing the bad sound.

Did you try lowering the sample rate ?
On the mame 32 screen click "options"
click "default game options"
click "sound"
lower the sample rate from
44100 to 11025
This should get rid of most of the crackling audio.

That's quite a rate drop

. I don't think this is the problem. Mame32 0.61 worked perfeclty fine. It's been since 0.62 that the crackling has started (for me). And we're talking cracking in Galaga, Donkey Kong, all the old games that SHOULD NOT be running poorly on anything newer than a P133

Audio breakup in Donkey Kong ?!

You need to find and adjust the settings for the onboard sound in your control panel or disable it and buy a seperate sound card. Personally I would go for a seperate soundcard. The newer versions of mame need every bit of juice that you can give them so you don't need onboard sound and graphics controllers freeloading off of your cpu.

I don't think the problem here is with the soundcard. I have been having the same problems here with mame .62 and higher. I have tried regular mame, and mame32. Both crackle even on less demanding games like hypersports. mame.61 works perfectly, mame.62 crackles and studders.

Give "64" a whirl

Like I said earlier, I'm running me a Sound Blaster Audigy

. Don't have an onboard sound chip. I think I'll try 0.64 and see how that works...

I have a soundblaster Live! and get the same thing (on some games)
Take gauntlet II for example.. sometimes the sound crackles where it shouldn't... game runs great no slowdown.. but sound crackle.. very annoying

Does .64 seem to work well for most? Also is it just mame32 or does the windows mame have the same prob?

hyiu · « **Reply #13 on:** February 03, 2003, 03:30:12 pm »

I don't know if this is related...

when I'm playing Alien Syndrome... (its like top view... you're a boy/girl... running around...disarming the bomb... shooting aliens... and then escape.. go shoot the boss...)

this game... when I load it with Mame32 v.58, it runs PERFECT.... but when I run the same rom with mame32v.61... the screen, gameplay... all stuffs are perfect... BUT... some (just some) sound cracks off....

I'm running on Win ME... AMD 1.7G, 256M Ram, GeGorce4... my machine should not have problem running it... that game shouldn't be that demanding.... could it be the driver got updated ??... you know... game still compatible... but not 100% compatible or something ??...

is this the same problem as the others in this thread ??

or I could be just plain out of my mind.... (which is very much possible also... haaa haa haa...)

I had this too, and I fixed it in a slightly odd way. Midway games especially crackled on my computer, and I have a soundblaster live. I played around with the sound options in mame and still got the crackling. After tinkering around this is what I figured out:
Go to the "options" menu and then to "default game options." Now you're thinking I'm going to tell you to go to the sound tab....wrong!! Go to the "advanced" tab. Under direct draw try unchecking "switch resolutions to fit" and "switch color depths to fit." I also unchecked "synch to monitor refresh." In fact for the midway games the only ones I do have checked are the "triple buffering" and the "stretch using hardware."
Try the games now. If you still get the crackling, play around with some of those advanced options. You can always set them back later. If you're using an arcade monitor (not a computer monitor) do all that at your own risk. I have no clue what it may do.
I do not know why this worked. Give it a shot and see for yourselves. For the midway games I also had to set the sound option to 22050 and it worked. (Just the 22050 without editing the advanced options did not fix the crackling. I had to do both.) It's wierd. It doesn't make much sense to me, but it worked. Hope this helps.

In Midway games you have to adjust the game setting within mame. Its f2 or f3 I believe (I'm at work, can't remember off the top of my head). You can then adjust the level of the sound "in the machine" from there. Read about it in the mame faq at www.mame.net.

I would say splurge and get yourself a simple soundblaster 16 PCI ($20 shipped from newegg.com). I've built a couple of mame computers for cabinets and this one works great, has dos drivers too if you choose to run dos mame (may never happen for you, but I run arcadeOS as a frontend). I haven't noticed any problems with this card.

As was recommended here as well, update to the newest version of mame v.64. They have been doing a lot of work on system sound drivers lately and that may eliminate some of your problems.

It's F2 and that only alters the volume. It didn't fix the crackling problem I was having either. After doing what I mentioned above, I have the in-game volume at maximum with no problems.

Jets: if its a VIA chipset-based modo, go to viaarena.com and install the Hyperion drivers. That should help:
