Appear noise. This problem is appear when enabled dmix plugin through configuration file ~/.asoundrc. ====================================================================== ---------------------------------------------------------------------- Xero - 06-08-05 22:13 ---------------------------------------------------------------------- As per advice from the bug on xmms I'm going to try the crossfade plugin to do some resampling. It only supports 44100 and 48000 but I'm guessing that with 48000 and 96000 set on dmix this wont happen...only time will tell however. ---------------------------------------------------------------------- Xero - 06-09-05 04:57 ---------------------------------------------------------------------- ok using crossfade and running at 48000 with dmix at 96000 still causes distortion. Also, I tried 48000 at 88200 and distortion as well. So far only 44100 and dmix at 88200 has no distortion. I'm guessing it might have to do with buffer size but I'm unsure as to what value would be a large enough increase to properly test this out. I don't want to add too much latency...
