Cannot control volume with amixer command
#1
Hi everyone,

I am using Rock64 and trying to play mp3 files on headphone jack. The playback part is working fine. I having trouble with controlling the volume with amixer command. When I try amixer sset Master 100 it shows me error "Cannot find simple control 'Master',0"

The reason behind the use of amixer is I have ported this application from raspberry pi and I need to keep it consistent on either device. I am using Debian stretch minimal image.
Exact version:
Code:
Linux rock64 4.4.77-rockchip-ayufan-136 #1 SMP Thu Oct 12 09:14:48 UTC 2017 aarch64 GNU/Linux


Also, amixer scontrols command does not return anything.

Kindly help.

Thanks!
