Ok so for the last few days i have heard some faint sound coming from my room when all is silent. So i decided today to try and investigate it..
I have found the source of the sound and it's coming from my speakers... Now i have the Logitech X530 speakers which have a power on button and a volume adjust knob on it, when i have the volume knob turned down to 0% i hear what sounds like several germans talking almost like a german radio show.
I would try and upload the audio but i can't seem to transfer the file from my phone to PC as the memory card says it's not inserted when the recording is on there, yet when i delete recording it appears fine.
Someone is casting a tf2 medic transformation spell upon you.
This has happened me many times. Not a german radio though, it was mostly just normal swedish radio or police radio.

It's definetly german audio, also it doesn't affect me when i have the speakers turned up, it's only when the audio is at 0%.
Also it happens when the speakers are both plugged in and unplugged from the PC
Id Be shitting Myself. Might be neighbors Watching TV?
I am quoting a google answer:
[quote]Hi toolofthesystem-ga,
This phenomenon is known as "radio frequency breakthrough
interference". It occurs because the speaker leads are acting as an
antenna and picking up the radio wave, converting it to an electrical
signal.
There is then some kind of nonlinearity which demodulates the radio
wave, producing the audio component. This could be, for example, a
corroded joint acting like the crystal in a traditional crystal set
and rectifying the radio frequency signal, producing an audio
frequency signal that makes a sound when it passes through the
speaker.
The following short article may prove useful to you:

I trust this provides the information you are seeking. If not, please
request clarification.

Are you sure that the sound is coming from your speakers?
I have this too, though it sounds like Russian
I used to Get the Same thing on my old crappy radio, When ever I would Change the Frequency you could hear fait german in it
Sometimes what sounded like police radios would randomly blare through my old speakers, but only for a moment, and make me think I was going crazy
This is common. The speakers are picking up radio interference from a German radio station. If I'm correct this happens only at night? The radio signals are bouncing off the lower atmosphere.
I have the same type I think, it happens here too, I read it was a common problem. But the volume adjust thing does the trick.
Wish it happened with my headphones
Poorly shielded wires or internal connections are doing this.
They're acting like an antenna, and the signal is then being amplified by the speaker set.

I get this often. It's trucker radio though. Also some sort of Monkey scream sound effect. It's weird.
it's your mom watching porn
lesbian porn.
My friends dad had an old radio that picked up old Soviet radio frequencies with failsafe codes and stuff, it was freaky and awesome at the same time.
Its not your radio, its the germans in the room beside you.
Planning.
Speakers are badly shielded. I heard of more Logitech speakers that also pick up radio frequencys, but mine don't.
The German language scares me.
I was screwing around with my bro's wireless headset once and managed to hear my mom and dad talking on the phone :P
This happens if my volume is on max.
Me too

[quote]The Mac G5 (and all Macs) have superior shielding and are unlikely to be the source of RF interference. (Ever see PC's with "cool" windows and lights in the case? Idiots. An open invitation to RF interference).
For external speakers, connected (I'm assuming) with a 3.5mm mini phone jack, there are plenty of possible sources.
The 3.5mm plug itself is a poor choice for minimizing RF interference; two channels have a separate + signal wire and a common shield. The shield also acts as the - connection for both channels.
For that to work properly, each positive wire and the negative/shield must have the same electrical qualities. This is difficult when the shield also carries the - signal, as the wires are of completely different construction.
At the connector, it could simply be a poor solder joint or connection, or the connector may be physically failing. Replacing the connector might solve the issue. In some cases, you can re-solder the connections, but at the price point of these speakers it's almost guaranteed that it's a moulded connection of PVC, which you can't open to repair.
PVC also gases off corrosively as it ages and it's a common cause of cable failure over time; the copper wire simply corrodes to death. Sometimes there is nothing short of replacing the cable and/or connector that will help once that's happened. (Ever see "green" copper inside clear speaker cables? Now you know why).
Since PVC is cheap and the good stuff is relatively expensive, any inexpensive cable will eventually fail; they all use PVC coated wire (the jacket, which is what you see on the outside, can be PVC if it's not touching the shield, but in cheap cables it almost always is).
There is also the possibility the jack on the Mac is not properly making connection. This is typically a more difficult fix, as it sometimes involves working on the computer motherboard. You can check it by substituting a known good speaker system and see if the problem persists. If it does, I suggest using USB or the Optical Outs for audio, as a mobo or other part is too valuable to play with for what is essentially a minor problem (doesn't affect the computer's ability to do other things).
It could also be a poor connection at the speaker amplifier (inside one of the speakers, usually; the one the cable from the Mac goes to first). Again, checking and re-soldering might solve the issue.
The cable itself (a "cable" is any combination of wire) may have an open shield or other physical failure. Replacing the cable can solve that one.
Since these speakers are typically powered by a "wall-wart" there is another possibility. The wall wart is typically DC and shouldn't introduce problems from the wart to the speaker, but the wart itself has AC (the source of hum) and it could be failing in some way, introducing AC to what should be a pure DC signal.
The in-speaker amplifier could be failing or otherwise have poor connections somewhere.
So, here are your options:
Try to alter the polarity of the wall wart. Simply reverse it so that it plugs into the wall the "other" way. This may reduce grounding problems to an acceptable level. If it's a polarized plug (one blade slightly bigger than the other, to avoid this very problem) you may not be able to do this.
Go to Radio Shack and buy an el-cheapo cable; 3.5mm mini to whatever is cheapest that day. Cut the cable at the un-needed end (leaving a length of cable with the 3.5mm plug attached) and replace the cable on your speakers with it. Pay attention to cable length; ideally the positive L and R wires should be exactly the same length and the shield securely soldered inside the speaker with the amp. Although there is no "right" length for the shield which is completely different in construction than the other two wires, standard practice is to insure it's the same length as the other two, which should help with radio interference.
Finally, it may simply be the source of RF is close to you or otherwise easy for you to pick up. Radio waves are everywhere, all the time. In order for a radio wave to be easily "picked up" we use an antennae. For this purpose, all you really need to know is that the antennae must be of a specific length to pick up a specific frequency. So, altering the length of your cable from the Mac to the speaker/amp (which is the antennae in your case) will kill it's ability to pick up that frequency.
Shorten the cable by some relevant amount. Although a random change often works, you can avoid problems by insuring the length is more correct.
Length divided by any number or multiplied by any number is equal to the same antennae. So, cut the cable and resolder it at a shorter length, but avoid even multiples or fractions of the original length.
Eg: original cable is 1 meter long. Avoid 1/2 meter, 2 meters, etc. Also avoid multiples of these numbers (since 1/4 meter is also verbotten, don't try 3/4 meter either). Hack off 3 or 4 cm and re-connect. This is perhaps the easiest fix, as you can do it anywhere along the wire; wherever it's convenient for you.
This may also be necessary in the wall wart's cable; we don't know which cable is the real cause so it may be necessary to do both to find out.
If, after replacing or shortening both cables, you still have a problem, then it's either the speaker's amp itself, the connection at the wire and speaker, or the connector on the Mac. Stop there and give up.[/quote]
That's really cool.
