Using Ardour 2.1 on an HP dv6000 laptop. NVidia onboard soundcard (yes, 
I know it's crap, but this is just my little on-the-go editing box), 
Ubuntu Feisty.  Two mono tracks - playback only, 48khz 16bit.  Running 
linux 2.6.20 kernel.

Nope, no xruns or disk warnings.

Nope.  Behavior is the same with only a single mono track playing.  
Sounds kind of like an overdriven signal being played through a badly 
blown speaker, but the signal levels are all appropriately low, no 
clipping anywhere in the chain, and the source files playback fine on 
the same speakers when not being played through ardour.
