Your right this sympton may be specific for the cs46xx, I've been experiencing this sympton with JACK and Ardour several times. The sample rate should not matter. My guess is that internal buffers occasionally get unsynchronized inside the DSP, may happen on playback too. The only I've found to get around the problem when it happens is to restart the playback or capturing process. /Benny ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
