Been trying to fix this for longer than I can remember, and recently decided to give it another go. My BK sound is working, but it's playing the incorrect sounds and speech calls. It's been an intermittent problem, doesn't always do it. When it does, though, the incorrect sounds/speech calls are always the same ones. I've crimped new female connector pins, and re-flowed solder to male pins on sound board. I tried a sound board from my buddy's BK and it worked fine, which leads me to believe the MPU and wiring is good. I just replaced the PIA today, but the problem remains--in fact it will only play the incorrect sounds since installing it (for as long as I've tested it). I did try re-seating the ROM and CPU chips at some point, and the problem went away for a couple hours. Turned the game off, then later turned it on and it was back to making the wrong sounds. I did have the board professionally serviced years ago, and it worked fine until the past couple years. There are new caps and the 4 bigger chips on the board all got sockets. not sure what else was done on it, though. I don't believe the ROM chip has ever been replaced, and I'm wondering if that should be my next move. Another sound-related issue that may be another symptom: The background sounds (hard to describe them, but it's like DUN-Dun-dun DUN-Dun-dun) start playing shortly after the game is turned on, and it continues right through diagnostic tests until I do the sound test. As soon as I advance from the sound test, the background sounds start up again. It never used to do that, and I figure whatever is causing the problem may also be responsible for that. So, any ideas what to check?

Thanks!

Never did manage to get to the bottom of it. It's been working fine for the most part, it's just when I start to think it somehow 'fixed itself' when it finally rears it's head. Once the holidays are over, I'll get back in there and see if I can put the issue to rest.

Only clue I've been able to come up with is that if I remove the sound and speech boards from the game (disconnecting the 40-pin ribbon cable between the sound and speech boards, too), it usually works fine after I put them back in and hook them up--at least for a while. But, then out of the blue it'll act up again--so I can't really say if the 40-pin cable has anything to do with it or not. Seems like it might, but I've been unable to prove it so far. I did recently re-solder the 40-pin connectors on the sound and speech boards, but haven't had the time to test it since. I'll post a follow-up if I make any progress.

Good luck with your Jungle Lord, penguinchicken! Please post here if you find the solution!

Just wanted to follow up on this one--i think it's finally fixed. Re-flowing the headers at 1J8 on the MPU board had helped, but the problem gradually returned. I replaced IC36 thinking that would fix it, but the problem persisted. I finally replaced the headers at 1J8 on the MPU and I'm pleased to report no more weird sounds nor random attract mode nuisance sounds. The problem had gotten pretty consistent, making it a bit easier to narrow down. Flexing the connector at 1J8 finally revealed the issue. Perhaps my re-flowing skills could use a revisiting, but regardless I'm happy to see the problem finally put to rest with the new connector. Hopefully this will help someone else down the road.

It's funny--the problem caused certain speech selections to change sometimes, and it had gotten to the point that the end-of-game speech was often the Knight's laughter!
