It seems after I sleep-wake cycle my laptop something screw happens so that play back of music -- specifically using mpg123 to play mp3 files -- after that point produces a fair amount of static.
Here is an odd part. If I run aucat as such: $ aucat -ddddd <much continuous output> the static is almost nonexistent, while reducing one of the -d options makes the static more noticeable. Suggesting keeping aucat "busy" reduces static significantly(?). Any ideas? What other info would be useful?
