Thanks to everyone for all the replies. I definitely needed to change the permissions on the xastir binary, that helped. The permissions on /dev/soundmodem0 were already 777 so I didn't do anything with that.
FWIW, on the same box, I'm running an XP virtual machine with soundmodem and it is receiving. I shut down that VM and switch to Ubuntu and I'm not getting anything. I have to assume it's something with ALSA, the various capture devices, or mixer settings. Thanks for the help. I may just switch to a hardware TNC if I can find a decent one supported by linux!
