This well known (and in this case amplified) noise is what I really do not like on MSX. It's always there. No matter what.
To avoid as much as possible interferance I cut pin 49 on all my sound cartridges (I never use my monitor's speakers). Still it's there. One cartridge suffers more than the other. You'd expect cartridges with jack connectors to not sends the noise from the MSX itself to the amplifier, but both the pin 49 cut cartridges and the jack cartridges still carry a lot of very unwanted noise to the amplifier.
Is there really no way to keep the MSX's ugly noise completely outside the audio signal? Sure, once something's playing you don't hear it, but there's not always something playing. It just has to be gone... Forever...
Any solutions?
