I don't remember exactly what was off, whether it was just the display or whether it resulted in different audio. Nevertheless it's annoying and I don't quite know how to get rid of it entirely. Maybe display -0 or +0 as 0? In some languages you need to be tricky to achieve even that, java comes to mind as it treats -0 == +0. _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
