Good thinking, I wondered about 100Hz (sounds like the system clock
frequency).  Unfortunately, no, it doesn't eliminate it.  It makes the
100Hz 'ticks' worse, if anything, and I still only get the right-hand
channel.  When I set it to 16 bits (with the format == 1, not extended)
it's fine (but at 16 bits).  As a dyslexic young friend of mine says,
I'm confussed...

It's not really a  very high rate, the sound card (and other software
using the same system and hardware) goes up to 24/96kHz quite happily.

Thanks for pointing me at that system call, it will be useful in other
places...
