imx8: alsamixer and no controls

I'm currently running Freescale BSP on imx8mqevk(4.9.88-imx_4.9.88_2.0.0). 

Now, I have a problem with audio controlling. The speaker itself is working fine but there's no volume control. I could play audio files via aplay command but opening up alsamixer just says "This sound device does not have any controls".

 

here is the list of the detected sound cards:

$ cat /proc/asound/cards

0 [wm8524audio ]: wm8524-audio - wm8524-audio
                              wm8524-audio
1 [imxspdif ]: imx-spdif - imx-spdif
                     imx-spdif
2 [imxhdmiarc ]: imx-hdmi-arc - imx-hdmi-arc
                           imx-hdmi-arc
3 [imxaudiohdmi ]: imx-audio-hdmi - imx-audio-hdmi
                              imx-audio-hdmi

 

 

Any assistance would be appreciated.
