S+ No Reel Spin Sounds, all other sounds work

[bigphxguy]

Hi all...Newbie to the forum here.

I have a S+ 4th of July with an SP1271 Game Prom chip.  I've read several other threads and have seen two possible solutions to my problem, but neither seems to correct my issue.

My dip switches are set to 1-on, 2-on, 3-on, 4-8 off.  However, if I understand correctly, the dip switches do nothing for the SP1271 chip.

In my self test setttings, test 2 is set to 1, or on, which results in the reel stop sound coming from the solenoid instead of the speaker.  I still get my "spin to win" sounds when landing on the 4th of July symbol on reel 3, coin drop sounds and "win" sounds" are all there...just no reel spin sounds.

If I change self test 2 to 0, or off, I get the reel stop sounds through the speaker instead of the solenoid.  That seems to be the only thing that changes when I change this setting.

Has anyone else seen this problem before?

Thanks in advance for any help.

Very odd. I've never heard of this.

2-1 would be the correct setting. That outputs spin music and diverts the stop pulse to the solenoid because the sound chip wasn't capable of producing both sounds at the same time.

Have you tried going into the sound test page and trying each of the different sounds?  Press the test button until you see a 50 in the winner paid window. (I think it's 5 presses.)
Turn the JP key to change the sound being tested and press the spin button to test each sound.

The spin "music" is actually composed of 4 separate tones comprising a C major triad with an octave. See if each of those tones works, as well as the rest of the test sounds. That will at least confirm whether there is a problem with the sound chip. It's possible that the spin sound data is corrupted.

I've gone through all the sound settings and I get tones on every selection.  The sounds are there....they just won't play during a spin while playing the game!

Very perplexing...

As noted, the stop sounds always come from the solenoid. But see this thread about a similar issue I had with the PRS.

Also, I would go here and verify you actually have a SP1271 in there regardless of how it may be marked. BTW, the SP1271 does not give you as many sound choices for the bonus spins. A SP1048 is a better choice.

No they don't. In fact, the thread you've linked to points that out. When 2 is set to 0, there are no spin sounds and the stop sound is synthesized through the speaker. When 2 is set to 1, there is actually NO stop sound, and the handle release solenoid is actuated, creating the illusion of a stop sound.

According to his post, he's tried setting 2-1. Since he can hear the coin-in sounds and the music during the respin, we know that his volume is turned up and that the speaker/amp hardware is working, as well as at least some of the sounds generated by the sound chip.

Now that he's run the 50 test and has heard all of the sounds, that puts this squarely in the "strange" category.

[poppo]

No they don't. In fact, the thread you've linked to points that out.

Yeah, you are right. That was so long ago, I didn't re-read the whole thing. I just remembered the PSR being missleading.

But he should verify the SP chip is a 1271.

[StatFreak]

Hmmm. I wonder if it's possible that the SP1271 is corrupted. Maybe the subroutine that calls the spin sounds isn't being called, or the subroutine code is corrupted. But wouldn't that cause the chip to fail the checksum test?

It might be worth trying a different SP chip, and perhaps even a differend SS chip (for giggles) to see if that solves the problem. If you have another MPU board, you might also try swapping it out.

[bigphxguy]

I'll see if I can get my hands on another MPU and a SP chip.  I'll give it a whirl and let you know what happens.  Thanks for the ideas!

[bigphxguy]

Does anyone have a digital copy of PSR1271 they wouldn't mind sharing with me?  I'd like to go through EVERYTHING and see if I can uncover something that may solve my problem.  Thanks!

Here you go. But check that link I posted above to make sure you actually have a SP1271 in there. Would not be the first time a chip was mis-labeled.

[bigphxguy]

Thanks poppo!  I checked the chip on the LED display...it is indeed a 1271.  I suspect a corrupted chip.  I'll be swapping chips later today...we'll see if that fixes my issue.

[bigphxguy]

So I threw my MPU board in another S+ machine, and voila!  Spin Sounds!  So I know it isn't the MPU or the SP chip.  Any ideas as to what else could possibly be affecting my reel spin sounds?  Again, all other sounds are audible, so it isn't a speaker or sound hardware issue.  Is there anything else in the actual machine (aside from the MPU) that could be causing this issue?

[poppo]

I suppose you might do a clear if you have the clear and set chips to do it. Some settings are stored in the EEPROM on the motherboard.

[knagl]

Yeah -- I'm stumped, too, but I'm with poppo -- at this point a clear wouldn't hurt and I really can't think of anything else that would cause this.

[rickhunter]

The last time I had weird behavior on my S+, I had to clear eeprom for it to go away.  So at this time, I would do a clear.

[bigphxguy]

I just ordered a clear chip on eBay.  I was hoping it wouldn't come to this, but now I'm having an unrelated issue with being unable to change my page 0 option 8.  It's locked up at 2 and won't convert bills to credits and I can't change it...even after using the set denom chip.

Arrrrgggggghhhhhh!  Looks like I'll be waiting for the clear chip.

Ha! I knew we would see this again.  Read this first post. You first have to change it with the set chip. Basically there are 2 places you need to change it.

But also make sure you didn't have any credits on the machine when you tried to change it.

[rickhunter]

Remember, you can't change any options if you have credits on your machine.

[stayouttadabunker]

Hmm...I thought he had spin sounds when installed in another machine...
maybe it is possible there are some options and settings saved on that motherboard chip?

I'm almost certain that an IC component isn't shifting a register along it's path
and it's also possible that there's an diode completely out of specifications due to heat, age,etc.etc.
Chances are the 1k resistor that sums up the sound generators current sources - is getting out of whack.
When you put it into the other machine - it kind of woke it up! 
I'd pull out the microprocessor chip and re-insert it to give new life to it's leg pins...
Be very careful as this is a very long chip with a whole boatload of pin legs.
It very possible the certain legs on the microprocessor chip have become oxidized
and started to work from the jarring the MPU got as you banged it around removing and installing it.

OR

the motherboard chip in the other machine has those particular settings saved?



Clearing a RAM on the motherboard may not help as there are no sound bytes stored on that particular chip...
The sounds on an S+ are stored in the AY-3-8912 programmable sound generator chip.

BUT there MAY be some settings that you need to change?
Remember to remove all credits from this present machine in order to change settings.

The theory at this point is that there's some kind of corruption in the eeprom on the mainboard, and that's why the MPU board is working on the other machines, but not on the one in question.  That's why a clear seems like the next step.

[stayouttadabunker]

Are there credits on the present machine?

Can he set the [2-x] to a [2-1] ?

Yep, that is my thought too. Most if not all of the settings are stored on the EEPROM. That is why you can pull the CMOS and you won't lose the settings after you clear the errors and it re-loads them from the EEPROM.

[stayouttadabunker]

If he has a bad ground on the resistor or speaker in THAT CABINET -
he will not have sounds....
however, he does have "other" sounds...so I'm stumped.

I'd do the clear by sticking a magnet to the legs on the motherboard serial eprom -
WITHOUT the MPU installed!
That will definitely force the MPU to rewrite new data to the motherboard eprom.
He will get the [65-1] "Bad EEPROM DATA" error code which basically means the EEPROM data is "invalid".
or a code [67] "data eeprom changed"...
No problem, open and close the door optics will force the MPU to rewrite to the EEPROM.

[StatFreak]

I see that I'm late getting back to this thread, but I'll throw my hat in the ring with everyone else and suggest a full clear, as some sort of data corruption seems to be the most likely cause, and the evidence points to the EEPROM.

He did that back on page 1
