Grease is the wordHey Mikey,
Still having issues with noise on the plug in boards? I was still having pops on SPDIF reads but didn't what t whine whine whine. Bought some Silver bearing conductive grease and it cured the damned issue for good. I mean it this time.
I applied by squeezing a bit out on a card and dipping a short toothpick in then with a very small dab I spun it into each slot hole. then I too some hypoallergenic swabs I got for like $1.29 at the CVS perfume counter and wiped off the remainder laying on top. Plugged in and sooooooo quiet now. No friggin random pops.
Might even pop in the up-sampling board next ... then again, maybe now.
Stuff costs about $30 but this small tube seems like a lifetime supply.
