Sound and audio options
The player’s Quality, audio and subtitles panel has a Sound section: choose surround or stereo, focus on dialogue, tame loud scenes at night, level volume between titles and fix lip-sync. You can pick a different soundtrack in any version; the Sound options are in Beebo for Windows (Beta, since 0.1.58).
Beta Status: The Sound section is in Beebo for Windows (Beta, since 0.1.58), and the Android test download has the HDMI passthrough switch. It has not been tried on real receivers, TVs or across all browsers. Picking an audio track and the picture quality work in every version. Passing HDR10+, Dolby Vision, Dolby Atmos and DTS:X through to a TV or receiver is In development, so Beebo does not claim support for those formats.
Available today
While something is playing, the gear button opens the Quality, audio and subtitles panel. If a file has more than one soundtrack, they are all listed with the language, the number of speakers and the sound format. See Quality, audio and subtitles.
Step by step
-
Open the Sound section
In the web player, or the Android and TV player, tap the gear button. In the Quality, audio and subtitles panel, find Sound.
What you’ll see: A line saying what is playing, in plain words, for example “Stereo (mixed down from 5.1) · AAC” or “Surround 5.1 · Dolby Digital”.
Screenshot coming. The Sound section of the Quality sheet in the web player.
-
Choose the sound mode
Auto (the default) uses surround sound only when your device says it can play it. Stereo mixes surround sound down to two speakers. Surround keeps 5.1 sound (six speakers) where your device can play it, using Dolby Digital Plus or Dolby Digital, or AAC 5.1.
-
Choose how surround folds to stereo
When surround sound is played on two speakers, Beebo has to mix it down. Stereo mix-down: standard is a normal mix that stops loud scenes from distorting. Stereo mix-down: dialogue focus makes the voices louder and lowers the effects and bass.
-
Night mode and volume levelling
Night mode makes loud and quiet parts closer in volume, so explosions are quieter and whispers are easier to hear. Volume levelling keeps the loudness similar from one title to the next. Levelling makes the PC work harder (roughly a third of a processor core for 5.1 on our test PC), so it is off by default and the panel says what it costs.
-
Boost dialogue and fix lip-sync
In the browser player, Dialogue boost makes the sound up to 6 dB louder without distorting it. Audio delay moves the sound up to half a second earlier or later, to match people’s lips. On Android, the delay comes in five steps and the PC makes it. Where possible, the browser makes the boost and a later sound itself, so the PC does not need to convert the video.

Android and TV: HDMI passthrough
The Android panel adds HDMI passthrough: Auto and HDMI passthrough: Off. Passthrough means sending the sound to your TV or sound system (receiver) without changing it. On Auto, Dolby Digital, Dolby Digital Plus, DTS and TrueHD go to a receiver as they are, when the device says it can take them. Off makes the phone or TV turn them into ordinary sound itself. The panel then says what actually reached the output, read from the device, for example “Sent to your TV or receiver as Dolby Digital Plus (5.1), undecoded”. This is an early version and has not been checked on a real receiver. Full passthrough of HDR10+, Dolby Vision, Atmos and DTS:X is In development.
What you’ll see: Sound choices are saved per account with your other playback settings. Passthrough is saved on the device.
What it does and does not claim
- Only what it can play. DTS, TrueHD, Opus and FLAC soundtracks are always converted by the PC when a phone or browser cannot play them. Seven-channel sound is folded to 5.1, not dropped.
- No object audio. Beebo does not keep Dolby Atmos or DTS:X when it converts a soundtrack, and it never labels a conversion as either. Passing them through intact is in development, and we do not claim it today. The words in the sheet describe what you are really getting, including “converted from DTS”.
- Copying when nothing needs doing. If your device can play the file’s Dolby Digital, Dolby Digital Plus or AAC (up to 6 channels) and you have not asked for night mode, levelling or delay, the sound is copied untouched and only the picture is converted.
- Music. Beebo reads ReplayGain tags in your music files and levels loudness without re-encoding or changing the files. Songs with no tag are levelled using a loudness Beebo measures itself, once it has measured them.
- Not yet verified on real receivers and TVs, on every browser’s handling of multichannel HLS, or on a TV remote. Tell us what works for you.
If something goes wrong
I chose surround and hear stereo
Your device or browser did not report that it can play surround sound, or a headset is connected (a Bluetooth or wired headset always means stereo). Check the line at the top of the Sound section, which says what is being played.
Conversion makes my PC busy
Levelling, night mode, delay and surround all ask the PC to convert the sound while you watch. Turn off what you do not need. See the encoder choices in Settings, in the section about quality choices for phones, TVs and browsers.
My phone only offers 480p (or Original and 480p)
Workaround for older builds: a saved sound setting (volume leveler, night mode, audio delay or the stereo mix-down) makes your home PC convert the audio, and the phone app then picked only a 480p conversion. On one phone, turning the volume leveler off brought the Original choice back. To try it, open the player’s Quality, audio & subtitles panel and turn those sound settings off, then pick your quality again. This workaround was confirmed on one phone only. Repaired in Android tester67 (build 117), a test download published Nov 2, 2026, 3:47 AM Eastern: with Night mode, the volume leveler, a delay, Stereo or the dialogue-focus mix-down on, a 1080p film stays 1080p on home Wi-Fi and other direct, unmetered connections; on slow or relayed links (and on mobile data) the picture may be lowered and the phone says so; and a "Turn off sound settings" row in Quality, audio & subtitles puts them back to normal. It was checked on a Pixel 3 and a Galaxy S9+ only, so it is not a general result; on an older build, or if it does not help on your phone, use the workaround.
Dialogue is out of sync
Try Audio delay. If a positive delay does nothing in Safari or Android Chrome, that is expected: those browsers play the stream themselves, so the PC makes the delay instead.
I do not see a Sound section
It is in Windows 0.1.58 and newer. Update the Beebo PC and reload the player. Check What’s new.
