Also before I forget - the clock patch has two modes, standard and delay mode. It might be worth swapping this to see if anything changes.
The two lower solder bridges are connected.
This is how it was delivered.

Have you done the SDMA Patch ?
The patch was not installed.

@kohli79 yeah you need to try changing it to the top position instead to see if it agrees with your falcon more.

Ok thanks, I could test that. But I don't think that solves the problem. 🤔

Why not? The problem you face is a clock/dsp sync issue.. which is what the clock patch should resolve. This is probably the best thing to try first. I have asked around and what everyone tells me is 'try different types of clock patches' and nothing more.

I've tried it now and at first I was very happy!
At first everything was green and no disturbances!
But suddenly everything red again after about 20-25 seconds in the test.
See youtube link! (unfortunately reversed :roll: )

Try some freezer spray on the chips and see if the problem goes away...

I've already thought about that. I have now ordered some. 🥶 I also have some coolers there ...

Btw, this dsp/sound issues may arise from heat as well. I've had the exact same problem with my CT2 Falcon - it works nicely but if the lid is closed and heat amounts to certain value, I hear it again.

The Falcon is currently still open. What I noticed so far is that the D/A (STV8438CV) gets relatively hot a few minutes after switching it on. All the other ICs/chips are also the DSP in the normal range! Perhaps that is also normal with the D/A?
I have to wait for the cold spray first, then we'll see ... I want to find the cause! 😈
