Ok, I see it now, but  then I put these commands in /etc/rc.local



echo  "loopback=yes" > /sys/class/sound/hwC0D2/hints
echo 1 > /sys/class/sound/hwC0D2/reconfig


and I get this, and almost empty mixer

I had to reload the driver and apply the above commands to make it and
loopback work...


Why? It all did work fine before.
