Hi Garin,

Ah-hah! Thank you for reminding me to try the other implementations! I 
am using Windows XP and I was using alcOpenDevice(null) which maps to 
the NVidia native driver on my system. Seems this is another problem 
with my native driver, because both generic software and generic 
hardware work fine.

As you know from my previous posts to this list, I have been bitten by 
this driver a couple of times before (so the cause of this problem 
should have occurred to me sooner this time!). I will change my code to 
specifically use the generic hardware device to avoid the native driver 
so it doesn't happen again!

Thanks!

Nic
