[LAU] Horrible number of xruns in Jack (Emu card)

[bradley newton haug]

I find the sound quality inferior on the maudio offerings, but the linux
support is rock solid, you can get a 1010lt for cheap now.

the emu1212m is a really nice card hardware-wise, just needs a little more
linux love on the driver side.
