Most likely your headphones are not shielded. You are picking up a GSM/EDGE/IEEE802.11 radio frequency.
Solution: Try headphones with shielded wires.
Thanks for the suggestion! But sadly, it doesn't seem to work. I tried 4 different types of headphones - among them at least two of very good quality (Grado SR80, Etymotics ER4P, and then Koss Porta Pros and some cheapo Sony earbuds). All of them had the same funny noises.
So if it would have to do something with unshielded headphones, then I suspect that many people would be able to reproduce this symptom of headphone noise during wireless activity. Maybe some other forum users can confirm or tell if its the same with their NC10?
And the noises are very clearly connected to activity on the WLAN - they only are there, while _loading_ a youtube-video for example. As soon as all the data of the video is loaded, the noise stops. So that would speak against the noise being sourced by GSM/EDGE/..., right?
Hoping for further help/ideas,
EDIT: tested this under Windows (I am keeping a dual-boot still) - the noise is there, but it is _much_ more silent, almost unnoticable - not disturbing at all... have to crank up the volume to the max to be able to hear it (and then the music is unbearably loud with my etymotics headphones :-).
So... this is most definitely a Software(Linux)-issue. (Which I am happy for... at least it's not defect hardware.)
