Consider adding a comment section in the sender-audio.sh on how to select a specific sound card...

Managed to get chance for another brief play around with this at the weekend.

At the moment the soundcard is set to:

ASOURCE="autoaudiosrc"

But this has the problem that it can select the wrong soundcard if you have more than one. (I have 1 soundcard for game audio and a usb sound card for microphone/voice audio when using discord)

In the end we used the following command to list the available cards:

pactl list | grep -A2 'Source #' | grep 'Name: ' | cut -d" " -f2

and then changed the ASOURCE to the following:

ASOURCE="pulsesrc device=alsa_output.pci-0000_00_1f.3.analog-stereo.monitor"

I am not sure if this is the correct way of doing it but it did work so I am assuming it is :)
