It sounds like you have your recording input set wrongly on your sound
card. You need to have it set just to record the line input. If you set
it to record everything you will find myth records it's own output and
plays it back over itself until you are in feedback hell!

Just change this setting using your favourite mixer (kmixer, gmix,
smixer) and hopefully that will help.
