Greetings,
I have a S+ that has no sound during game play with door closed, but in test mode(50) there is sound. Dipswitch #3 on MPU is on. Am I missing a setting somewhere?

Do you know what SP chip your machine has installed? That will let us know what specific options and settings your machines has. If you don't know your SP chip number here are some instructions to find out:

The newer SP chips rely on a menu setting, not the DIP switch settings, to enable spin sounds. As rokgpsman posted above me, we'll need to know what SP chip is in your machine to give you proper instructions.

Hi Guys, thanks for the quick response. It's a Triple Play -- SP1271

Attached below is the document for SP1271. There is a white TEST button inside your machine, are you familiar with it and how to enter the machine's menu system for seeing the settings and making changes if needed? I'm not an expert on this but it looks like menu option #2 is for sound, it should be set to 2-0.

I didn't see a setting for volume control. We'll see what advice others give.

With NO credits on machine open door press white button 2 times. This will bring up 2-0, press spin to change to 2-1, shut door. You should have sound now.

Since this is a 10mhz mpu the only volume adjust is the volume pot on edge of mpu board, correct?

correct

ok, thanks! Since the sound setting will be either 2-0 or 2-1 and both those settings give some sounds why would there be no sounds? Does doing a Clear ram process leave the sound setting in limbo and you actually have to select 2-0 or 2-1 to get some sound enabled?

sixcardmark · « **Reply #9 on:** March 21, 2018, 09:03:30 AM »

edit- 2-0 you get the reel stop sound only.

sixcardmark · « **Reply #10 on:** March 21, 2018, 09:21:49 AM »

I edited earlier post, no need to keep pressing white button after changing 2-0 to 2-1 just close door.

2-0 does give sound beep reel stops
2-1 gives melody while spinning but reel stop sounds are from coil.

Hi Guys;
The sound is set to 2-1 and the sound works in test mode(50). But during game play the sound doesn't work at all. The owner of this machine had it worked on in Vegas a couple of years ago and the sound didn't work after that. All of the other functions of the machine work perfectly even the BV. Is there a mystery setting somewhere? I'm thinking that the problem is on the MPU board. What do you think?

I have exhausted all troubleshooting for this sound issue and wondering if I should do a RAM clear as a final attempt? What do you think? The sound is set to 2-1 and the sound works in test mode(50). But during game play the sound doesn't work at all. The owner of this machine had it worked on in Vegas a couple of years ago and the sound didn't work after that.

What could it hurt! since you know how to get into the test menus , get a set of the diagnostic flip cards .go through the menus and write down all your settings, then after the clear, you will have to restore some, usually, 5_0, the bill unit settings, perhaps the hopper settings, etc. in any case we can always help you through that procedure.

I read through the 1271, dip switches do not apply, so if you have it set to 2-0 or 2-1 you should get something?? could something be wrong with U-49 or its associated circuitry?

tech40 · « **Reply #14 on:** March 22, 2018, 01:55:59 PM »

Thanks for the reply Jim. I guess there could be something wrong with U49 however, the sound works in test mode? Does that rule out the Sound chip/U49?

What about trying another set of Game and Reel chips? They don't cost that much, maybe the problem is something goofy in the software. What was the work that was done to the machine you mentioned earlier, that after the work the sound stopped happening during game play? And didn't the person that did the mentioned work notice that the sound went away after whatever he did?

tech40 · « **Reply #16 on:** March 23, 2018, 05:53:39 AM »

I asked the machine owner what was done to the machine in Vegas by some other tech. He didn't know what he did or even why he brought the machine in, as it was about two years ago. Possibly a battery?
Maybe it is the software! Any idea where I might be able to pick up a new set of game and reel chips?

rokgpsman · « **Reply #17 on:** March 23, 2018, 09:32:44 AM »

There's probably several folks here on NLG where you could get another pair of Game & Reel chips. You can send a pm to Jim at Midwest Slots (see his message above), or Ken (ohio gaming) or RB, among others. Or just post a Want-To-Buy message saying that you need the 2 chips and someone here will move it for you to the Classified Ads area. If no one here has what you need there are places online that have them. Keep in mind that replacing the Game & Reel chips is a longshot to fix the sound problem, you might want to try doing a ram Clear first.

If you order the software chips you'll need to tell them what your chip numbers are. They are called "SSxxxx" and "SPxxxx". You can look directly at the mpu board, the chips should have labels on top that show the SS and SP numbers. On the mpu board the chips are called GAME and REEL, it is written near one end of the chips, which are in sockets. Post a photo of your mpu board if you need help finding them.

Or follow these easy instructions and the chip numbers will be shown on the front displays.

In your other discussion thread you said the SP chip was SP1271. And the machine is a Triple Play, so just need to find out the SS chip number.

If you do replace the SS chip on your machine this could be a good time to install an SS chip with a different payout percentage, if you've ever wished your machine had a higher percentage. IGT made several SS chips for your machine, each with different payback percentages, depending on what the casino wanted. For the Triple Play machine the percentage can range from as low as 83% up to 98%. For example, if your current SS chip has a percentage of 90% you could replace it with one having a percentage of 98%. That might make it a little more fun to play and as long as you are replacing the chip anyway might as well order one with a higher percentage.

If you already have a Clear chip and want to try that first to see if it fixes the sound problem that would be faster. If you don't have a Clear chip then you could get a Clear and SET chip while you're ordering the SS and SP chips. The SET chip is often needed after you Clear the ram, the SET chip enables the bill validator and is sometimes needed to set the denomination and other stuff.

I don't think you've posted a photo of your mpu board. I'm wondering if it's possible that during the previous work the mpu board was replaced and they might have installed a 16mhz style mpu, and then used the GAME and REEL chips from the old 10mhz mpu on the new 16mhz mpu (or vice-versa). You can get some weird compatibility problems when you do that.

Does the mpu board in the machine now have a round blue volume control on the top edge? If so then it is a 10mhz style mpu. But if not then it is a 16mhz mpu.

I have merged the two threads you created for this issue into one thread. Please do not create multiple threads for the same issue.

Have you tried the page zero option 2 setting of 0? I seem to recall that the IGT documentation was backwards when it came to the reel spin sound setting.

Are you hearing anything at all when in game play mode? Do you get a ding when you drop a coin? Are you hearing the speaker-generated reel stop sound when each reel comes to a stop?

If you have tried both settings for option 2 and it still isn't working, and you're not hearing anything at all from the speaker when the game is in its normal operating mode, then yes, I agree with Jim, there's nothing to lose at that point trying a RAM clear.
