Yes — LineageOS 23.2 (Android 16) supports this via ADB, no volume key needed.

Read volume levels

The media volume command prints the current value with --get:

adb shell media volume --stream 3 --get   # music/media
adb shell media volume --stream 2 --get   # ring
adb shell media volume --stream 1 --get   # system
adb shell media volume --stream 0 --get   # call/ringer voice
adb shell media volume --stream 4 --get   # alarm
adb shell media volume --stream 5 --get   # notification

Example output:

media volume: stream 3 is currently 10 of 15    # current / max

Run adb shell media volume to see full usage. On modern Android this media shell command exists specifically to read/set stream volumes (AOSP source history, Stack Overflow).

Alternatives

• Full state of every stream at once (verbose but complete — includes muted state, per-stream index/max):
  bash

  Copy

  adb shell dumpsys audio | grep -A 20 "STREAMS"
  # or: adb shell dumpsys audio

• Show the on-screen volume slider without touching the keys (this makes the same UI appear as pressing a volume key):
  bash

  Copy

  adb shell cmd media_session volume --show --stream 3

  Without --set, this pops up the volume dialog without changing anything (Stack Overflow).

Notes

• Stream numbers: 1=system, 2=ring, 3=music, 4=alarm, 5=notification; you can also use --get with --stream names accepted by cmd media_session volume (e.g. --show --stream music).
• To make the on-screen slider pop up without ADB, some launchers/automation apps (e.g. Tasker with the "Volume Dialog" intent) can trigger the same dialog.
