+### Duplication
+
+An alternative device audio capture method is also available (only for Android
+13 and above):
+
+```
+scrcpy --audio-source=playback
+```
+
+This audio source supports keeping the audio playing on the device while
+mirroring, with `--audio-dup`:
+
+```bash
+scrcpy --audio-source=playback --audio-dup
+# or simply:
+scrcpy --audio-dup  # --audio-source=playback is implied
+```
+
+However, it requires Android 13, and Android apps can opt-out (so they are not
+captured).
