On the other hand, I wonder what part your USB sound card contributes to
this problem simply because it's USB? USB transfers are pretty small. This
causes the system to require more packets and packet headers to get the same
amount of data moved. I wonder if the USB portion of Linux could be
contributing to this problem? It may be that those of us using PCI based
audio cards don't suffer this problem at all. I certainly haven't noticed
any of the things your are talking about.
Yes it's true that this could be directly related to the usb side of
things. Only if I run alsaplayer in realtime with lotlat, rtc and root
priv, through the alsa native interface this doesn't happen.
I know that JACK puts more stress on the systems interrupts so it could
be that running such a demanding app with such high priorities supecedes
the usb code slightly. I'm not sure if that is possible though. Anyone
know how to check that?

Being on stage with the band in front of crowds shouting, "Get off! No!
We want normal music!", I think that was more like acting than anything
I've ever done.
