I have been using a Zoltrix Audio Plus 6400 3D PnP (AV309) in my 5x86 system without issue - it is basically noise free with or without the speaker amplifier.
Out of curiosity I replaced it with this Acer Magic S23A (CS4236B) card I had laying about, thinking it could be even better due to being more integrated. I also wanted to compare CS4289's OPL3 vs CS4386B's.
However, this card is attrociously noisy. Not only is there a very high and very annoying high background noise, but it also picks up noise from all across the system - ISA Bus, PCI Bus, IDE activity, you name it.
This does not sound normal to me and I THINK it has to do with dried out caps, but wanted to ask your opinions first. Should I attempt a recap of this card, is this something normally known to be silent and well filtered?
