Reading the XBUFFSTAT register is by no means accurate. IIRC, it reports the buffer status incorrectly about 1/50 times on average (@ 48000khz); with simple math, it may be read during the DMA burst. Or is it guaranteed not being read during DMA transfer / have you otherwise verified the behavior?
Do you remember how big was this variation? Was it near the burst size or some arbitrary difference?
