Hmm ok, I wasn't sure about aqualung backends before, since it says it can output to OSS, ALSA, Jack, or Pulseaudio.
But the interesting part is that the xine-ui frontend incorrectly detects the bitrate of the file as 16 instead of 24. Since the Phonon backend we're using is xine, that means that this error could be occurring when Amarok plays as well, since xine is in the audio chain (Amarok -> Phonon -> Xine -> ... -> speaker). I think the version you labeled as libjack1 should actually be the version of xine-lib. It seems that you have installed jack-related packages from this PPA. https://edge.launchpad.net/~motin/+archive/until-jack-is-included-in-main If possible, could you please confirm that the same noise occurs with the xine-lib in main as well? So here are the new questions: 1) Does the noise still exist with xine-lib in main? 2) Is playback still noisy playing files with xine-ui in a terminal? (you said it misdetects the bitrate, but not whether or not it still sounds noisy) I'm going to go ahead and direct this bug towards xine if your answer to (2) is yes. After that, we'll need to file a bug upstream, since I have no idea what direction to go in to fix the bug, and this is something that upstream would be better able to handle. -- noisy playback of 24bit/96khz flac files https://bugs.launchpad.net/bugs/503361 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to amarok in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
