  • Since Android 8 there is adb sheel media volume available. To get a well-formatted values of volume streams: for s in $(seq 0 100); do media volume --stream $s --get 2>/dev/null | awk -F'[()= ]' '{if($3=="control") printf "%-22s %-3s: ",$7,$5} {if($2=="volume") printf "%-3s %s \n",$4,$7}' | grep ^STREAM || break; done. You will get all stream names/numbers, their current values and possible values. Commented Dec 30, 2019 at 19:44
  • To set media volume (MUSIC_STREAM) to maximum: media volume --stream 3 --set 25. Where 3 is media volume stream and 25 is its maximum value. It's also possible to use service call as explained in above linked answer. Are you trying to change in-call earpiece volume or some other? Commented Dec 30, 2019 at 19:46
