In short:
modprobe tsn modprobe avb_alsa mkdir /sys/kernel/config/eth0/link cd /sys/kernel/config/eth0/link <set approriate values vor the attributes> echo alsa > enabled aplay -Ddefault:CARD=avb some_song.wav
Likewise on the receiver side, except add 'Listener' to end_station attribute
arecord -c2 -r48000 -f S16_LE -Ddefault:CARD=avb > some_recording.wav
I've not had time to fully fix the hw-aprams for alsa, so some manual tweaking of arecord is required.
Again, this is a very early attempt to get something useful done with TSN, I know there are rough edges, I know buffer handling and timestamping is not finished
Note: if you don't have an intel-card, load tsn in debug-mode and it will let you use all NICs present.
modprobe tsn in_debug=1
