I think the two 'amixer' commands go at the end of the ".profile" -- I
missed that filename the first times I read through. Also note it
begins with a 'dot'.
And can I tag onto this thread (or should I start a new one?) I am also
playing with a RPi3 and have low volume problems but with the HDMI
output. (Haven't tried the 3.5mm output.) The volume does adjust using
the [ and ] keys but maximum is barely audible through my monitor's
speakers. I did not notice a change after adding to .asoundrc and
adding the two commands to .profile (and rebooting). Also tried max_dB
30.0 -- no change. Different commands for the HDMI volume or did I do
(Decided to add HDMI to Rajil's post to sort of link the threads.)
