Orange Pi Zero + USB audio card + LIRC

I encountered a strange problem and I do not know what to do:
When I am restarting my OPI with inserted USB audio card, then LIRC does not work.
When I am restarting my OPI without inserted USB card and this USB card I put only later after a restart, then LIRC works.
Can anyone advise how to proceed? I need to insert USB audio card permanently (it's inside the device).

So I figured it out.
Maybe someone will have the same situation.
The solution is simple:

1) command cat < /proc/bus/input/devices - it gives a different result, if the USB sound card is plugged (device "sunxi-ir" is shifted down) !

2) I had to edit the file /etc/lirc/hardware.conf.
There I originally had the line DEVICE="/dev/input/event2".
Now (with attached USB sound card) I had to change it to DEVICE="/dev/input/event3".
