Are we able to clone or does it makes sence, if different setups (6581 / 8580 + AOUT_LC) are used?
Does someone have an idea, why my ‘both’ 6581R4 are soundless while activating filter?
Best Regards, Rio.

I have many 6581 that go silent when you turn on the filter, I assume that means a broken chip.
they are completly unused… and both have the same behaviour - only in HP area, i can listen to a bit sound.

It isn’t a SW related issue if the filter don’t work. I would propose to check the filter cap connections, the filter cap values, and if this doesn’t give you a hint, check the SIDs on an original C64 just to ensure that it isn’t related to your MBHP_SID module

Chances are is that the filter section of your chip is toast. I’ve got a 6581 with this problem. I drop a good one in the same SID module and the filter works fine. You either stuck with getting a new chip or using an external filter.
they are never used before… and same type R4. I get only in trouble with R4. I’ven’t checked on a real C64…
Just unlucky dude… often they are dead when they are ‘new’. In the biz we call it a DOA.
