I,ve installed raspbian image in my bpi-m3 and volume control doesn’t work. The master of the speaker always stays at zero and i can’t change it. I’ve searched for solutions in different forums without success.
I’ve try different comands in console like amixer sset Master 100% amixer cset numid=1 – 100% > /dev/null amixer cset numid=3 2 trying to switch the audio output to HDMI … and none of the solutions has solved the problem.
Could someone guide me to solve the problem? Thanks.
