try something like

sudo ./tx -d plughw:2,0 -h 239.0.0.1

e.g. define the audio source. Now, I know it's at times confusing which device to use.
I have an ICOM Transceiver connected via USB:

roeland@taplop:~/src/arbitrium/trx> arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: PCH [HDA Intel PCH], device 0: ALC3227 Analog [ALC3227 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: CODEC [USB Audio CODEC], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0

and above takes the raw data from the second card, the audio codec of the transceiver.
