I mean current situation:

#i2cdump -f -y -r 13-13 1 0x1b
Result: 0x00
#arecord test.wav &
#i2cdump -f -y -r 13-13 1 0x1b
Result: 0x00
# amixer sset 'Headset Detect Enable' *on*
#i2cdump -f -y -r 13-13 1 0x1b
Result:*0x80*
#killall arecord
#i2cdump -f -y -r 13-13 1 0x1b
Result: 0x00
#arecord test.wav &
#i2cdump -f -y -r 13-13 1 0x1b
Result:*0x00
*#killall arecord*
*amixer sset 'Headset Detect Enable'*on**
*#i2cdump -f -y -r 13-13 1 0x1b
Result:**0x00
**#amixer sset 'Headset Detect Enable' off
*amixer: Invalid command!*

So state of 'Headset Detect Enable' and others of my controls were not 
stored during arecord/aplay restart (open and close device).
