The reason I thought it was my app was playing wave files over & over 
using aplay didn't result in the problem. It's possible aplay is using 
the interface in a different way (for instance I'd imagine it uses the 
plughw interface).
It's a scientific application that cannot allow distortion, or even 
xruns to occur at all (every sample is critical).

I didn't even know there was an rc6 !  Normally they get announced on 
the list. Must have missed it.
Can anyone in the know shed some light as to whether rc6 changes are 
likely to help ?
