My alsamixer is missing PCM, Master and some other controls

Hai!
 
We work on customized linux distribution. We used our own gui to control volume. We used to change volume by command
amixer -c 0 set PCM 20%  like that. Recently we changed our sound card, we are using realtek hda ALC262. I enabled the support for this card by enabling intel hda options in kernel. Now amixer is working, sound is coming but there is one problem, the Gui which we used to control volume is not working because the amixer control PCM is not there. Instead of PCM the volume is controllable using Front control. When I saw output of amixer I did not see some important controls like PCM and Master, instead I find new controls like Front and Line. Why this happened? How to get PCM an Master and other controls, so that there would be no need to change my program to set volume. I am sending my amixer output  and oss_mixer file in proc.
 
amixer output:
