I’ve had a Roku Streambar since 2020, and for years I just assumed the flat, boxed-in sound was as good as a soundbar this size could get. Then I went looking for a “Virtual Surround” setting everyone online kept mentioning, and what I found instead changed how I watched.
My Streambar is the original 2020 model, not the Pro, and Roku only ever added Virtual Surround to the Streambar Pro and the Smart Soundbar. According to Roku’s own sound settings support page, Virtual Surround is only available on those two devices, either on their own or paired with the optional Roku Wireless Bass. Mine? Never going to get the update.
My Streambar has real hardware for this, Roku just wasn’t feeding it right
Four drivers, angled on purpose
The base Streambar packs four small drivers inside, two front-firing and two side-firing, angled specifically to throw sound toward the corners of the room instead of straight out. When Roku launched the Pro model, the company said the original Streambar wasn’t getting Virtual Surround because those angled drivers already did their own version of that job. That’s marketing-speak, for sure, but it’s also a clue. The hardware is doing spatial work whether or not there’s a toggle for it. The question is more about getting the audio it needs to do that job.
Turns out, the Volume mode I had the Streambar on was flattening the audio. The Leveling and Night mode options, which even out loud and quiet scenes, come with a tradeoff. It’s like picking PCM over Bitstream on a TV’s audio output: the device decodes and simplifies the signal before it reaches the speakers built to handle the full version. Roku’s volume management page says that movies and shows streamed in a surround format like Dolby Digital, DTS, or Dolby Atmos may get converted to stereo when one of these volume modes is active.
I’d turned Leveling on years ago so late-night viewing wouldn’t wake anyone up, and forgot it was there. Every 5.1 track I’d watched since was hitting my Streambar’s angled drivers as flattened stereo, which meant those drivers never had a real signal to spread around the room.
Turning it off, and fixing the setting underneath it
Where to look
While you’re watching a show or movie, hit the * button on your Roku remote. Click on Sound settings, then Customize sound mode. Choose Off instead of Leveling or Night modes. These are the ones hiding the surround-capable audio.
While you’re in the audio menu, check to see if you have a Preferred streaming format option. Set it to Dolby if your streaming service supports it, or leave it on Auto. Check Digital output format, too. According to our Roku settings guide, this should be set to Auto or a specific format like Dolby Digital, not Stereo, or Roku will keep flattening the sound before the signal ever reaches your speakers.
My Streambar doesn’t have these settings, so your mileage may vary, as well.
What changed for me
Worth the dive into Settings
It’s not like I suddenly had surround sound on a device that doesn’t support it. But turning off Leveling mode made everything seem a little bit more alive, like it had more of a spatial aspect to it. Movies with explosions and ricochets sounded more real, more like a home cinema, than before.
What it does is let the drivers I already own receive the full surround mix instead of a pre-flattened one, so whatever spatial trick those angled drivers are built to do actually gets a chance to happen. If you want genuine discrete surround from a Roku device, you’re looking at the Streambar Pro or Smart Soundbar paired with wireless speakers, not a settings tweak on the base model.
If your priority is keeping volume consistent for late-night viewing, know that Volume Mode and full surround processing are a tradeoff on this hardware. You can’t have both at once, so pick based on how you actually watch. There are many other Roku options you might want to check out, too, including some for visual fixes, not just audio.
My Streambar sounds like itself again
I’m not going to pretend a base-model soundbar competes with a real home theater setup. But knowing that Leveling had been stripping every surround track down to stereo for years, on hardware that was built to do something better with that signal, was worth the two minutes it took to fix. I’ve kept Volume Mode off since, and I’d rather reach for the remote during a loud scene than lose what my Streambar was actually designed to do.
