For me these settings provide reasonable playback and capture volumes
using v4.10.1:
amixer -D hw:0 set PCM 100%
amixer -D hw:0 set 'Line DAC' 80% on
amixer -D hw:0 set 'Line' on
amixer -D hw:0 set 'Left Line Mixer DACL1' on
amixer -D hw:0 set 'Right Line Mixer DACR1' on
amixer -D hw:0 set 'Jack Function' 'Headphone'
amixer -D hw:0 set 'TPA6130A2 Headphone' 80%
amixer -D hw:0 set 'Jack Function' 'Headset'
amixer -D hw:0 set 'AGC' off
amixer -D hw:0 set 'Input Select' 'ADC'
amixer -D hw:0 set 'Left PGA Mixer Line1L' on
amixer -D hw:0 set 'Left Line1L Mux' 'differential'
amixer -D hw:0 set 'Right PGA Mixer Line1L' on
amixer -D hw:0 set 'Right Line1L Mux' 'differential'
amixer -D hw:0 set 'ADC HPF Cut-off' '0.0045xFs' 'disabled'
amixer -D hw:0 set PGA 50% on
amixer -D hw:0 cset iface=MIXER,name='PGA Capture Switch',index=0 on
