First of all, i have headphones and a bluetooth dongle that usually stays connected to my pc's front panel pretty much constantly.
A new nationwide rock radio launched a couple of days ago so i wanted to show my support and wanted to listen to it while i'm doing errands.
Now, as most of you know the n900 does not, by default have a dedicated FM radio application. But there is one in the repositories. So i went and installed that. As i see it, the phone does not have a dedicated FM antenna so it basically uses some combination between the bluetooth antenna and the headphone wire. Nothing weird and unknown for the moment.
Note: I wasn't fond of the earbuds that came with the n900 so i used my usual ones (they are TRS as opposed to the stock n900 ones that are TRRS).
Today i was listening to FM radio using the aformentioned app. I got home and, while still listening to radio i powered on my pc, nothing weird yet.
Seing the pc was on i wanted to stop my "portable radio" so i just unplugged the headphones from the phone (at this moment my pc headphones were plugged into the pc). I have set my phone to autopause (or automute in case of the fm radio) when i remove the headphones and so the FM radio app muted itself.
And now for the weird part.
A couple of seconds after i removed my headphones i noticed a sound in the room. It was the same music i was listening to on my phone, but my pc media player wasn't running, no room radio was powered on. Than i noticed it and i said to myself WTF!? The sound was coming from my other set of headphones, the ones that were constanly connected to my PC. What!? How in hell?!...
So i unplugged them from the pc front panel, no sound, plugged them back in, music again, removed them, no sound, connected them, music again.
At first i thought i might have bluetooth included in the pc headphones or maybe somehow my n900 was using the pc's bluetooth to connect somehow to the audio. But my headphones are an old Panasonic model which does not have bluetooth and there was no way in hell my n900 could be connected to my pc headphones through a pc wireless connection.
Immediately i thought it was some kind of FM interference as the music in the pc headphones sounded kinda mono and the radio station was definitely transmitting stereo.
I tryed half an hour later to reproduce the experiment but to no avail. Does anyone have any insight into what actually happened?
