I'm using Xubuntu 13.10 on a Samsung Series 9 NP900X3C. Recently, I get a buzzing noise on the speakers a while after turning it on. At first I suspected hardware faults - but then I turned down the "system sounds" in the pulse audio volume control, and that made it go away! I can listen to sound from any other source. I can also record the buzzing by selecting the monitor as default fallback under the input devices.

What's the matter?

Edit: I used arecord to dump the noise to a file. I don't really know what to do with that, but looking at it of course the largest part isn't encoded characters. The parts that are, though, are either

a) chunks of lower-case letters


b) ~~}}|{{||}}~~

(or similar combinations of the same characters).

What the hell is going on?

Edit 2: After Google turned up some people having trouble with Pulse Audio and Skype, I quit Skype, and the noise is gone now. I had the sound turned down, though, so I don't actually know if that fixed it.

Edit 3: Confirmed, the noise returned and quitting Skype made it stop.

Thanks, restarting Skype made the job! Don't know why the question is on hold. You should be able to answer and accept your own answer. –  mreq Dec 15 '13 at 14:28
