I am experiencing a loud (and brief) white noise sound when starting up Mint. The noise sounds like a radio not tuned to any station.
The noise lasts about 2 seconds, and it happens after logging in, when the screen is black before Gnome has completely started up. It's not a huge problem provided the volume is set low, but if one of the kids has turned up the volume knob when I wasn't looking, the noise can be truly tooth loosening
Any ideas what could be causing this and what I can do to fix it? I am using Mint felicia at the moment. I also had the same problem with Elyssa, which was the first version of Mint I tried. I never had the problem with other linux distros.
I searched a bit on the web and found this potential fix:http://ubuntuforums.org/showthread.php?t=896015
....but it didn't work.
I also checked all my "sounds" settings and played all the system sounds...none of those are responsible as far as I can tell.
My hardware is a Packard Bell i-Extreme H5030 Gold, with a Radeon X300 graphics card, TV tuner (may be something to do with the problem???), ethernet card with D-link ADSL modem plugged in. I have a microphone plugged in to one audio input, and stereo speakers on the outputs.
