UDP Stream issue

[iz4tow]

Good afternoon,
I encountered an issue using UDP device on direwolf

Scenario

Audio sender: Windows 10 host with ffmpeg

Receiver: Ubuntu Desktop 22.04 with direwolf last release build from github today

On Windows host (audio sender)

ffmpeg -f dshow -i audio="Line 1 (Virtual Audio Cable)" -c 1 -acodec pcm_s16le -b:a 44100 -f mpegts udp://192.168.56.1:12000

I tried playing a test.wav generated with gen_packet and tested with atest.

On Ubuntu

If I try to listen the stream with VLC I can hear it loud and clear, but with direwolf with this command

direwolf -n 1 -a 10 -r 44100  udp:12000

Output:

Dire Wolf version 1.7
Includes optional support for:  hamlib cm108-ptt

Reading config file direwolf.conf
Audio input device for receive: udp:12000  (channel 0)
