I have an issue with intermittent sounds coming from the speaker that sounds just like a mosquito! Heh, don't laugh this is getting annoying Mepis is loaded with 2.6.10 kernel on my wife's Shuttle SS51g and there were some quirks setting it up. I used Japanese printer drivers for the Canon i950, I used ndiswrapper to use windows drivers for the wireless G USB NIC, and everything else is onboard except for the Winfast 2000 XP TV Tuner which was all autodetected normally. I've ran apt-get update upgrade to try to fix this to no avail. I haven't seen anyone else with this particualar problem and I've googled it up several ways... Does anyone have a clue what this could be?

I think there are multiple ways to render sound in Linux. ALSA is what I use and I think it's what Mepis uses as well, but there are other sets of audio drivers. I'm not sure how to do it, but switching to another set of audio drivers might fix things.

I've had that happen before as well...it happens when I leave on a program called amarok.
My wife has had the same thing happen to her too.

I'm pretty sure that it's amarok causing this in my case, generally
when it's left on for long periods. I'll come into the office and hear an
odd sound coming from the speakers. When I shut down amarok it goes away.

hope that helps...

Hmm, I don't have amarok installed on this machine, I will try killing pids & see if I can figure it out.

I had the same problem, turned out to be amarok (left it running).

I come to find that when I turn off the speakers, it's not coming from them, since it's intermittent I have yet to find out WHERE it's coming from... I have a epson 1240U scanner, Canon i950 & the TV Tuner which are suspect at this time...

Thanks for posting that. I had a good long laugh about that one... cuz I could totally see it happening to me. I'm just imagining myself running around my room with my ear sticking out trying to find out where the hell the stupid noise is coming from. HAHAHAHA.

Yeah! But the hardware's not doing this on a windows install, only with mepis... hmmm...

i had a radeon 9700pro that would make a whine...i think
i read somewhere that my power supply wasn't good enough
to support that card

i switched out the psu for a new one and the whine went away

??? good luck

Nope, it's not a fan-whine. I am using onboard video anyway... This sounds "just like" a mosquito... And no there is no mosquito trapped inside my case lol

Only thing besides the speakers that I might mistake for a mosquito are probably vibrations. Is the computer case touching anything metal or wood nearby? I had a weird sound coming out of a server intermittently and it ended up being the CD drive spinning up and causing vibrations that made a weird sound because the case was up against a metal cabinet. It was a sort of buzzing sound. I guess fans that change frequency or maybe harddrives could cause vibrations that could do this every once in awhile. The other thing I'd check would be the case speaker, those little tiny one inch speakers that make system beeps and that sort of thing. Maybe it could be freaking out.

Still imagining myself running around with my ear stuck out.

Turns out it was a capacitor going bad. Not sure why windows didn't use that particular capacitor enough to make it buzz
