I have 6 stereo outputs so it would take 2 emu10k cards. I started
development with one such card driving 3 rooms but had to move to USB to free
PCI slots for disk controllers.

Yeah, I wish I had hardware resample....
Without the USB 48Khz limitation I wouldn't even need to resample :-(
I have a feeling that 5% cpu load per room is going come back and haunt
me...

I haven't tried running the usb cards at 44.1 for several kernel
iterations, maybe it works now.
