I hope this is the proper subforum for this, if not apologies. I recently bought an ASUS laptop from newegg (specs unchanged so far) and since buying it I've only used it at home. It picks up an AM radio station nearby and plays it quite loud whenever I use the headphones. There may be an improper ground on our house's electrical system because on my old laptop and speaker system I could hear a very faint radio signal; however on this one it is LOUD and it simply doesn't go away unless I unplug.
If there's any sound playing, then the radio interception stops. It only occurs on headphones. Before anyone says "well don't plug in your headphones if you aren't listening to anything, dummy" it is pretty annoying to be doing some audio editing, and in between playing clips I get blasted with Spanish radio. It's like constant bachata torture.
I don't know if this is related, but when the headphones are plugged in, more than one audio stream will cause it to "switch" to the speakers. This is my first experience with IDT audio, so no idea if this is a common problem. Obviously this is a minor annoyance when I'm playing a game at night and suddenly I get a skype message, causing my game sound to blare out of the speakers and wake everyone up. However this would be a huge problem at a library or if I took my laptop to the office when everyone hears about 5 seconds of my music every time something else on the machine causes a sound. Since these both only occur when using headphones I think the problems are connected.
Could I use some sort of AC filter? Is there something I can do to make sure the laptop is properly wired?
