I've used a KISS DVD player with its internet connection and the sound also has "spikes". I guess that the KISS player runs with a old linux. And a friend of mine has tried the same files on 2.6.18 with another amplifier and the AC3 stream is decoded fine. So I guess that my old amp is the culprit.
