I know it's not the sound mix as I mentioned that I have the same issue with the original SD as the cleland mod and no, I don't have to high expectations as I mentioned that I compared this pin to Stern pros and premiums (TMNT, DP, JP etc.) and they sound way better. This issue is hardware related and other people seem to have the same issue but I haven't seen a solution for it.

Quoted from hocuslocus:

so no-one else notices this static/crackling noise? I checked the dead flip stream just to see if I was imagining stuff, and the crackling noise was there.
So I figured it was part of the code, and was supposed to sound like that for some reason. That is till I found another you tube video of a pro and the sound was crystal clear when the static was supposed to be there. it's right after your turn ends, right before the bonuses are added.
already tried replacing the CPU board with a new sim card, next I'm going to try the FF speakers to see if that does anything. (unless I got a crap replacement CPU board, I'm not sure what else it could be). Updated/reloaded the code a few times also.
it's not a big problem, but it still bugs me all the same.

Quoted from onyxx:

I purchased a GOTG LE a while back and noticed that the audio quality was poor/hollow compared to my other Sterns. I figured that something was wrong with the original 4" speakers and recently replaced them with Kenwood 5.25" speakers that Stern uses on other LE's and while the audio quality was improved it still sounds pretty bad. I have tried replacing the SD card with clelands audio mod and it sounds just as bad, I have also fiddled around with the customary audio settings and made adjustments according to recommendations in this thread but still have hollow and poor audio. The music is fantastic with the cleland mod but I just can't appreciate properly it because of this audio issue.
Is anyone else experiencing this and do we know of a fix that isn't "replace everything with pinwoofer"? I thought about adding an amp as LE's produced after GOTG all have amps, but I don't know if it will do anything for this sound. Even my Stern pro pins had good enough audio and didn't need pinwoofers in my gameroom setup. I read about Spike 2 CPU boards and audio issues with some builds further back in this thread but I have't seen anyone report back that replacing the Spike 2 CPU board fixed their issue.
The new 1.08 software notes say "Improve backbox and cabinet audio synchronization" but I don't want to upgrade if it doesn't solve this issue as I will lose my possibility to run clelands audiomod, has anyone notised better sound with the 1.08 update?
Any tips on how to solve this issue would be appreciated.
