After fixing my problem with many of my Wii games not working by running through the ultimate 4.0 guide again, I've run into another annoying problem. Since I installed 4.0, preloader, and CIOSCORP, all the sounds in the system menu sound very staticy and distorted. The games sound fine, but as soon as I bring up the home menu in the game I can hear it. Basically, all the sounds are almost like a low bitrate MP3... not sure how that relates to the Wii, but just by comparison that's all I can pull off the top of my head. I select something on the menu, and it sounds like a 32 bitrate MP3. Very staticy sounding, not very clear, and certainly annoying as hell in surround. I did a search and found someone with a "ringing" problem on their Wii system menu after installing preloader and CIOSCORP, and the problem was never solved. I'm not sure if this is the same situation as it doesn't sound much like ringing to me, it just sounds like I have cans over my speakers.
