Luigi Rizzo explained this behavior in the old pcm driver about a year or so ago. I believe it was due to some applications setting a fixed buffering size with the SETFRAGMENT(?) ioctl, which was not implemented in old pcm and then mistakenly writing smaller than intended sound samples because they assumed a different buffer size. I don't know if this applies to newpcm, but it sounds like the same symptoms. Check the -current mailing list archives for pcm0 and xgalaga.
