Slowed down usually means the stream is 48kHz but is being played at 44.1Khz. Often due to transcoding to PCM which are assumed to be 44.1Khz. Check how the stream is beingplayed/trasmncoded look at log after setting player.source set to INFO All non MP3 BBC stream are 48Khz. ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=108852 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
