Ok, here is what I did:

raspi$ pulseaudio -vvv

pc$ pulseaudio -vvv

pc$ pactl load-module module-tunnel-sink-new server=

- After this there is constant network traffic from PC to raspi.

pc$ paplay -d tunnel-sink-new.

- Network traffic is paused, but after a while there is distorted audio
from raspi. Network traffic is recovered.

pc$ pavucontrol

- Network traffic is cut and ended for good.

pc$ paplay -d tunnel-sink-new.
Failed to drain stream: Timeout

Logs can be found from here. I added line of dashes to logs after every
given command.

These were the latencies of the network:

Ping from PC In a flooded mode:

--- ping statistics ---
3000 packets transmitted, 3000 received, 0% packet loss, time 5259ms
rtt min/avg/max/mdev = 1.375/1.680/18.901/0.556 ms, ipg/ewma 1.753/1.536 ms

and with 1 sec interval:

--- ping statistics ---
3000 packets transmitted, 2994 received, 0% packet loss, time 3004010ms
rtt min/avg/max/mdev = 1.565/2.001/15.767/0.505 ms

Hopefully this helps...
