Here are some notes and packages for using two ICE1712 based cards (the 1010LT in this case) with jack and ardour. There is also a version of envy24control with some enhancements/changes.
Also, I am having big problems running jack on a laptop. I’ll post a more detailed question later. But one problem is trying to use setpci on an nforce3 chipset. Setting the latency works for devices connected to the pci bus. But some pci devices are built into the chipset somehow. Setpci claims to succeed on these devices, but then the reported latency timer value is always 0. I have found very little on the net about this problem. If anyone has a tip, I’d appreciate it.
