then it sounds like the specific problem for cs46xx driver.
i guess some drift occured during the sample rate conversion or so.
please check whether the same symptom happens on 48000Hz ?
 

Sorry that I've been lost from the list from a long time ...

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.
