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
