+<code bash>
+try something like
+sudo ./tx -d plughw:2,0 -h 239.0.0.1

+I added a USB Logitech Audio "card" on the transmit side. Now it doesn't error. Receive side shows errors.
+  * Try ''cat /proc/asound/devices'' to see the inserted Logitech Audio
+  * Try ''aplay -l'' to see ALSA output devices.
+  * Try ''arecord -l'' to see ALSA input devices.
