I've gotten my doubletalk lt and pc to work with the cvs code and the 2.4 test kernels. For the lt, it required unplugging the external modem and setting the sereal port on the kernel command line. For the doubletalk pc, I needed to edit the synth port list in speakup_dtlk.c to include the port where my card lives before any other ports. Very interesting. Don't i remember this problem from several months back? Josh
