Pinging the gang on this again. Still some niggling sound issues. A bit of semi-consistent crackle & pop on quiet sounds, especially end-of-ball sounds (probably most noticed at this time b/c music is off). And, as of a few days ago, the volume sometimes varies significantly, even going silent occasionally, or being consistent & well-behaved for a day or two.
Gotta love the inconsistent issues!
What I've done, which hasn't made any difference:
1 - Swapped sound board
2 - Swapped sound & program ROMs (9.4H)
3 - New 4ohm 5.25" left speaker from Marco, matching the original. New speaker had powder-coating on housing--I scraped some off to get continuity to the ground wire ring terminal.
4 - Wiggled speaker cables
5 - Wiggled sound power cables
6 - Wiggled ribbon cable going to sound board
Any ideas?
Thanks,
-Jason
Quoted from jasonbar:Quick question on sound. There are a handful of quiet sounds on my machine that have just a very little bit of pop or crackle with them. It sounds a little like what you might hear if your iPod headphone jack is a little loose--just a little crackle.
One is the first 3 notes of the TZ theme that play when a ball ends & the bonus sequence starts. Another is the crescendo of the rocket launch after plunging the ball.
I've run the sound tests & hear no issues with all songs/sounds played in the service menu.
I've gone through & wiggled the connectors/solder joints/wires between the speakers & the sound board--nothing loose there--I can't induce the crackle.
My guess is that those few quiet sound files just have little inherent flaws in them. Has anybody else noticed this?
Thanks,
