Hello, after years of use my sb16 ct2230 started giving me a "Wrong Base I/O Address or Audio Card is not detected at 220H" error. I tried everything i could regarding the software side of things. I tried using different motherboards but no luck. Do you have any suggestions on the hardware side?

Thank you.

Did any of the jumpers come loose?

No i double checked them and used new jumpers too. I tried different addresses like 240 but still nothing.

Can it be the voltage regulators or the oscillators? The capacitors all look fine.

Hi, it's been a while, but do you remember if you ever got the card fixed? I have a CT2230 with the same issue. Or at least a similar one, as FM synthesized music works in DOOM etc, but without any sound effects. Diagnose.exe/unisound can't initialize the card
