Raspberry Pi 4b with HifiBerry miniamp
I followed the description https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/ and can hear the sound.
But if I want to change the volume nothing happend. In alsamixer I selected my soundcard "sndrpihifiberry" the system gave me the info "this sound device does not have any controls". What did I wrong?
Thanks for your support
