No sound in Headphone (coudn't able to store alsamixer settings)

[Hemanta]

I have install ubuntu-mate-16.04 in my PC (Mother board -> Intel DG31GL) but couldn’t find any audio driver. Speaker is working but Headphone is not.

I tried alsamixer settings and it worked. But when I typed “alsactl store”,
terminal replies “alsactl: state_lock:125: file /var/lib/alsa/asound.state lock error: File exists”.

What should I do ?
