Well, intermittent means to me that it's just good enough that it works 
most of the time, or fails only under special conditions. But sounds 
like your card's probably OK. (Or there are things the Windows driver 
does with the hardware that the Linux driver doesn't - control register 
settings, work around for known-to-vendor-but-not-necessarily-documented 
quirk, like "Don't set bit 7 of this register".)

Not that you have this problem, but I discovered that my powered 
external USB2 hub induces noise when my USB sound card runs through it. 
No noise at all when the card is connected directly. Probably my hub (a 
cheap one) has grounding issues.
