Published specification
What is true of this model and changes how you fix it
- Official specifications3.0.2 channel layout, 5 transducers total — far fewer than the Smart Ultra's 9 speakers/5.1.2 layout, confirming this is the compact tier. Wi-Fi, Bluetooth, AirPlay 2, Spotify Connect, Chromecast built in, same as the Ultra.
- Type — compact Atmos soundbar (WiFi + eARC)A compact Dolby Atmos soundbar with up-firing drivers, connecting by HDMI eARC and WiFi. 'No TV sound' is the eARC/HDMI-CEC link; streaming/app is WiFi. Smaller than the Smart Ultra but with real Atmos height drivers.
- Voice & appBuilt-in voice assistants and Bose Music app setup; pairs with Bose surrounds and the Bass Module wirelessly for fuller sound.
- eARC + CECUse the eARC/ARC port and enable HDMI-CEC; power-cycle both to fix a lost handshake.
- Atmos dependencyIt decodes Dolby Atmos, Dolby TrueHD and Dolby Digital Plus, but if the TV cannot pass Atmos through to an attached speaker, you will not hear Atmos.
- Size and layoutA 3.0.2 setup with five drivers (two up-firing), 2.2 x 27.3 x 4.1 in, the same shape as the Smart Soundbar 300.
- What it supportsA 3.0.2 Dolby Atmos soundbar with optical and HDMI ARC or eARC inputs, a subwoofer output, Wi-Fi, Bluetooth, Chromecast, Spotify Connect and AirPlay 2, with Alexa and Google Assistant.
- No sound over HDMIBose says an LG TV needs soundbar firmware 2.2.0 or later, which fixed an HDMI communication bug in December 2022. Owners also report the supplied HDMI cable failing and fix intermittent dropouts by changing the TV's audio output format to PCM.
- Wi-Fi drops and interferenceBose says to keep other wireless equipment at least 1 to 3 feet from the soundbar, and some access points up to 8 to 10 feet from the soundbar, bass module and surround speakers.
- HDMI eARC inconsistencyBose's support article says CEC and ARC compatibility differences between TV brands can leave audio missing or intermittent over HDMI. The remedy it gives is an optical cable in place of HDMI, or a different Advanced CEC option in the Bose app.
- Intermittent sound that clears on resetOwner reviews describe the connection dropping and sound that vanishes or echoes, which a reset of the soundbar clears.

Exact questions
Questions that only have an answer for the Bose Smart Soundbar 600
Should I add a subwoofer to my Bose Smart Soundbar 600?+
The 600 is a compact Atmos bar, so its deep bass is limited by size — if you want more low end, it pairs wirelessly with the Bose Bass Module (such as the Bass Module 700), which is the intended way to add bass. That is a design characteristic, not a fault. For dialogue clarity without a sub, the soundbar's dialogue mode helps. Add Bose surrounds and a bass module through the Bose Music app for a fuller system.
Why is there no sound from my Bose Soundbar 600 over HDMI?+
Update the soundbar to firmware 2.2.0 or later if the TV is an LG, try a different certified HDMI cable and set the TV's digital audio output to PCM.
Why does my Bose soundbar lose sound over HDMI?+
Bose names CEC and ARC compatibility between TV brands. Try another Advanced CEC option in the Bose app, or use an optical cable instead.
