The culprit was the code which resets the audio codec to stop it making so much noise. I was all ready to blame the udelay() function but it turns out there was some bogus code in there which had its register addresses and values mixed up. Mea culpa. It behaves properly now. The modified bootldr/balloon.c is checked in to trunk.
