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.

If it helps you, see: https://www.volkerschatz.com/noise/alsa.html
