Bob, Do you have a reason to run uridiag? Do you suspect your uri is bad? If not there is no reason to run it. Perhaps app_rpt is running also? You would need to run that exclusively. Stop asterisk or reboot without starting it before running uridiag. You would need to make up the test cable as per the DMK site to test it. the snd-pcm-oss modules needs to be loaded. It creates /dev/dsp, /dev/mixer modprobe snd-pcm-oss to load lsmod to check if it is loaded - or ls /dev/dsp - is should be there. 73 Doug WA3DSP http://www.crompton.com/hamradio From: kk6ecm@gmail.com To: app_rpt-users@ohnosec.org Date: Mon, 14 Apr 2014 20:29:42 -0700 Subject: [App_rpt-users] /dev/dsp Any ideas how to solve this one? # uridiag URIDiag, diagnostic program for the DMK Engineering URI USB Radio Interface, version 0.8, 04/26/11 Found CM108AH USB Radio Interface at 002/003 Unable to re-open DSP device 1: /dev/dsp1 Segmentation fault Do I need a loopback?
