Remote Control Commands for Samsung WAM Speakers

WAM Bridge lets you control a Samsung WAM speaker from the command line without starting a new playback session. Status queries, volume changes, mute, pause, play, stop, and standby all go through Samsung’s port 55001 command API, which responds in about one second.

Status and volume#

# Print current speaker statuswambridge --device M5 --status# Set volume (raw step 0..30)wambridge --device M5 --set-volume 3# Mute and unmutewambridge --device M5 --mutewambridge --device M5 --unmute

The Shape M5 uses raw API volume steps 0 to 30. There is no model-aware percentage conversion yet. Step 3 is approximately 10%; step 30 is maximum.

Playback control#

wambridge --device M5 --pausewambridge --device M5 --playwambridge --device M5 --stopwambridge --device M5 --standby

Playback type caveats#

Control behavior depends on the active playback source:

Source type	Pause/resume	Notes
WAM Bridge URL stream	Pause carries PCM pipeline latency	Stop and skip also carry latency
Native TuneIn	CPM commands via port `55001`	Fast response
DLNA / Share	UIC pause and resume	Protocol-proven but not actively integrated

Warning

Samsung URL playback (WAM Bridge streams) cannot be reliably resumed after a stop. If you stop a WAM Bridge stream, start a new playback session rather than using --play.

Hardware volume routing#

The CLI --set-volume command already targets the speaker directly. The hardware_volume setting controls the foobar2000 volume slider during WAM Bridge PCM playback.

With the default hardware_volume=0, slider changes stay in the PCM pipeline and therefore follow its latency. Set hardware_volume=1 to route the foobar slider to the speaker’s port 55001 control path instead:

[wambridge]hardware_volume=1

On the tested M5 that direct speaker path answers in about one second. Pause, stop, and skip still carry PCM pipeline latency; hardware_volume=1 only changes volume routing.

Foobar2000 WAM controls#

The installed foobar2000 component adds these menu items under Playback > WAM Bridge:

Playback -> WAM Bridge -> Emergency stopPlayback -> WAM Bridge -> Stop & mutePlayback -> WAM Bridge -> Start sleep timerPlayback -> WAM Bridge -> Cancel sleep timerPlayback -> WAM Bridge -> Volume upPlayback -> WAM Bridge -> Volume downPlayback -> WAM Bridge -> Volume to safe level

All commands run through a serialized control helper and report completion or errors in the foobar console. Start sleep timer uses the sleep_after_stop preference as its delay; during active playback it routes through the running PCM helper rather than opening a second control connection.

Tip

For responsive volume control during active WAM Bridge streaming, prefer hardware_volume=1. For pause, stop, and skip latency, the work-in-progress improvement is on the speaker’s port 55001 command path rather than further shortening the audio pipeline.
