Can someone confirm the mpu switch setting for sounds

And also is it test no18 setting 3 for all noises .

It seems its just slipped to silent church mode.
Also I have been putting it in T18 and set at 03
And its never that when I return ontonthe self test
Its always 00

Hope that makes sense

Yeah they are were warm

One strange thing i did notice ...although It would be nice if someone could confirm this is normal.

When I got the game I didnt touch any settings as the guy had it set up for home use already.

We had all sound but the background rising frantic noise was off whilst in play
If you started a game and plunged the ball out it was all like that right through a game

If you started a game and waited for the ball shoot rising noise to end then plunged the ball into play it would then have the fanatic game sound on .... all though the 3-5 balls
Is this normal or another issue

Yeah I got that.
Maybe lost in terminology
Its holding no3
And all other settings high scores etc.

I'm gonna add here ive noticed the knocker is going off loads.
Today when kids were playing it mist of gone off 5-6 times
Rapid fire like

And often when you start a game it fires
