3.2 was shipped with UbuntuStudio 12.04 (Lowlatency) and I have done at

audio of my two machines (my netbook needs lots to work at all). I had
sometime before in the 2.6 kernel era moved my audio IF to a cpi slot that
did not share irqs, but that is about it. I tried lots of things, but that
was what made the most difference. 12.10 went to kernel 3.5 (I think) and
now 13.04 is using 3.8. All my machines are 32bit, don't know if that
makes a difference, and while the netbook has more problems... it is atom
based at 1.6Ghz and only 1g ram. Internally it has a PCIe bus, but I don't
know that has anything to do with it's audio problems considering all it's
other limitations. It can record audio through a midi IF with jack set
-p64 as well, so it is not that bad. (forget internal sound for low

PCI then, VIA/ICE17*. Is that the 1712 or the 172* (1720 to 1724 look the
same to the PCI IF)? 32bit system? or 64 (if 64 is the kernel 32bit)?
Newer (has PCIe HW as well as PCI)?
I wonder if any of the new USB2.0 IFs use the VIA1730, AudioBox 1818VSL
maybe? Seems to be the right number of i/o.
