Munsters pro on route, game sitting in attract mode and the speakers emit a pop noise over and over. Reseated plugs, still does it.

Code is 1.02 currently and I see 1.03 has a mode board update and audio fixes. I’ll try that soon.

But has anyone experienced this pop?

Edit:

From a cold boot it does take ~7-10 min for the popping to start. So it would seem like a bad solder joint or capacitor...

I know you stated the sound is coming from the speakers, in the video it sounds more like a small coil firing.

I verified it was speakers. Folded the speaker panel down and held my finger on the speaker. Also via listening. And it sounds like a speaker pop/crackle in person.

I can’t help you but I was on a location last week with 30 plus machines and sure enough the Munsters game speakers were popping during attract mode. It was annoying! I just wanted to let you know it’s maybe a Munsters thing and not just bad luck on your machine.

Dang! Hilton said he remembers it being a Munsters thing too!

So the notes for 1.03; are very audio heavy

PRO V1.03 - March 9, 2020
=========================
Tweaked:
- Removed Backbox GI from lamp effects.

Moved to SYS 2.44:
Updated to nodeboard firmware v0.57.5

Added UTIL->VOL Adjustment "SELECT AUDIO FILTER".
Values are: "NONE", "HIGH/LOW SHELF", and "10 BAND EQ".
Default value is "HIGH/LOW SHELF".

"NONE": No filtering will be performed on the audio output. Useful when
using the Line Out as input for an external device.

"HIGH/LOW SHELF": A High/Low Shelf Filter is applied to the audio output.
The Bass Frequency can be set to: 125Hz, 250Hz, or Disabled.
The Treble Frequency can be set to: 4KHz, 8KHz, or Disabled.
The Gain can be set to -12dB .. +12dB
On Spike 2 the Shelf Frequency and Gain can be set independently for
the BackBox and Cabinet speakers.

"10 BAND EQ": A full 10 Band EQ is applied to the audio output.
Sliders are used to adjust the Gain of a specific range of frequencies.
The Frequencies are: 31Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1KHz, 2KHz, 4KHz,
8KHz, 16KHz.
The Gain curve has a 60dB dynamic range across the -120 .. +120 Slider
settings.
On Spike2 the Gain can be set independently for the BackBox and Cabinet
speakers.

Allow the knocker sound effect to play completely when a replay is
awarded during the last ball bonus and ensure the normal game
volume is restored.

Added Standard Adjustment "MAX PLAYERS PER GAME". Values are 1 to 4,
with a default setting of 4. This can be used to limit the number
of players that can be added to a game.

Update:

Holy crap....

So I updated the game to 1.03 today. While it was updating you could hear the audio popping. Once the game rebooted and the node boards did their updates.....No game/music audio what so ever. However still audio popping.

I have unplugged CN2 aka backbox speakers and now it does not make popping noises but no audio....great...

I have popping on a Batman 66. It will stop for a day after unplugging for a few minutes.
The popping also kills all gameplay audio.

I should update

The cpu carrier board has the audio circut. And that failed. Stern had me work with the distributor and replaced my entire cpu/carrier board. Even out of warranty. Which was nice as that is a $600 part as they include the cpu and carrier board. IMO they should sell the carrier board separate. However if they would now replace under warranty I was going to desolder the components and try to repair.

All is working after that.

Thank you for the update. This will help me fix my machine.

Use your distributor and have them contact stern about a replacement. Our game was well over a year old and they covered the part.

Yup just had a Starwars pro low plays come In from a client with the same issue . It’s a failure on the cpu board . Took a video and description of the issue and sent it to stern. . Stern replaced the cpu as well .

I’m really hoping someone tries to fix one to see what actually failed so the community can document it.
