Oh shit, sorry! Must have been tired not to notice that.

Oh nice, thanks for that DSC.
I've only soldered a couple of things in my life, so I'll have to do a bit of research regarding a few of those terms in your message, should do the trick though!

Edit after google: Ok so, in other words, buy a 470uf capacitor, solder it between 5V and GND, (i'll have to find out where that is when I get home from work). Cheers!

You can cut the noise in half by adding a large cap across 5V and GND right at the power regulator pcb. Usually 470uf does the trick. It completely removes the noise on the CGB.

Well that's the thing, Silph - we don't really need the crappy speaker so it doesn't matter all that much, which is good.
And DogTag, the backlight I had in there originally was fine, no buzz, then I replaced it with another one, didn't like the colour, so put the original one back in there - then the buzz started. Maybe the DMG didn't like the second backlight.

I guess the LEDs on the backlight affect the speaker output in some way. I can't remember if the same thing happens in the stock line-out, but I think so.

Do you actually need the speaker?
I always just rip mine out.

Interesting, so it's fairly wide-spread then. I mean, it's not a huge problem or anything, providing you have a prosound DMG somewhere for recording, but I was just curious.

I have that in my 3 DMGs. I guess it's something inevitable.

same thing happened to me with my super clean red play it loud.

haven't been able to figure it out, changed the caps and everything and still buzz.

sucks alot

But I'd already installed a backlight a while back without any buzzing noises appearing....

Just changed out my backlight, put it all back together and now the DMG's speaker has a constant hum/buzz. Not noticeable while playing music or when using headphones. Probably a rookie mistake, if anyone has a clue on what went wrong, I'd appreciate it.
