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
1 [imxspdif ]: imx-spdif - imx-spdif
2 [imxhdmiarc ]: imx-hdmi-arc - imx-hdmi-arc
3 [imxaudiohdmi ]: imx-audio-hdmi - imx-audio-hdmi
Any assistance would be appreciated.
