Buzzing noise when using MegaSD

09 Sep 2019, 21:04

I'm having a problem where there's an audible buzzing noise when using the MegaSD. I haven't had this problem with my Everdrive X3. It's intrusive enough to detract from the enjoyment I've otherwise been having with it.

The Megadrive I'm playing on is a region modded European Megadrive 1, with Packapunch Scart cable and an official SEGA UK power adapter. I've tried on two different TVs and both have the buzzing noise. I'm guessing it might be that the power adapter has gone dodgy but at the moment I don't have any others I can test it with.

Any help would be much appreciated! :)

When are you hearing this buzzing? During CD games, cart games, loading, in the menu? The more details the easier it is to try and figure out what is happening.

It's as soon as I turn the system on with the MegaSD inserted. It happens through both the TV and the headphone jack.

Does the noise stop at any point or does it continue the entire time?

It's doesn't stop until I've turned the console off. Running a CD game or just a regular rom doesn't make a difference.

Here's a video with what it sounds like (sorry for portrait):

Yeah there is something really wrong there. That sound is exactly like the mains resonating through the audio channels. You say that your Everdrive doesn't do this? That's sort of weird since it also attaches audio to the same lines as the MegaSD.

But it could be because you have a x3 and the x3 doesn't have the same audio hardware as the X7. Which is more similar to the MegaSD but still quite different.

I'm not sure as I bought it pre-modded. The seller didn't mention anything about having replaced them.

I'll see if I can test it on a different Megadrive at some point, but I don't have access to one at the moment.

Yeah. Probably should have started with, "I bought it pre-modded." Pretty solid chance that whoever did your mod work did something wrong. You should not be hearing the power running through your audio. Might want to open the console and take some pictures. Maybe give some indication of what these mods are so we can track down what is specifically causing your problem.
