Humm, single period and hw_sync failed, this could be testing the 
robustness of the single-period code and its mapping on multiple DMA 
descriptors? I haven't looked at the alsa module in eons but can't the 
number of periods be forced to two with module parameters while keeping 
the timer-based schedulng?
