This may be OK. The buffer sizes between plugins can differ.
What are the parameters for direct record ? (use 'arecord -v' with plughw 
device).
Also, you may try to force the buffer size to 8000 for dsnoop (use 
period_size 2000, periods 4) in your dmix slave configuration, for 
example:
type dmix
    slave {
    	period_size 2000
    	periods 4
    }
If this works, it's probably a bug in the driver.
