Jupiter Lander cart missing sound effects

[TMS2764]

I have a SIDKick pico and a SIDKick pico 2040DAC with firmware 0.21. The SIDKicks are working well on several PAL & NTSC machines but the Commodore Jupiter Lander cart has missing some sound effects.

With the 2040DAC is this only after first power-up of the C64? (= does it work after pressing a RESET-button?)

[TMS2764]

Same behavior on power up or after a reset. The main thruster and crash sound effects work but all the rest don't. Start and ending tunes, side thrusters, fuel sound effects don't play.

I'll have a look, but it will take a while...

I'm in no hurry. Just trying to help. What I can say is that Jupiter Lander does work correctly once in a while. Maybe because I started another game previously. Its hard to reproduce and seems random. Once the game loads correctly all sound effects works fine. But if I load another game or reset then it behaves as before. I've never seen it work correctly after a power-up.
