The short answer
Turn on the audio device’s night mode or dynamic range compression, which reduces the gap between quiet dialogue and loud effects. Set every source device to output PCM rather than passing through surround formats, since format switching is what causes the biggest jumps. Turn off the TV’s own volume levelling if a soundbar is doing the same job.
The volume difference between a streaming drama, a live channel and an advert break is not your imagination. Broadcast audio is loudness-normalised to a standard, streaming services use their own targets, and film soundtracks are mixed with a huge dynamic range intended for a cinema. Your living room receives all three and has to reconcile them.
Fix 1: dynamic range compression
This is the setting that does most of the work. It reduces the difference between the loudest and quietest parts, so dialogue rises and explosions fall. Names vary:
- Night mode on most soundbars and receivers.
- Dynamic Range Control or DRC in TV audio settings.
- Auto Volume, Volume Leveller or Smart Volume on televisions.
- Dialogue or Clear Voice mode, which combines compression with a boost in the speech frequencies.
Enable one of them, not several at once. Stacked processing from a TV and a soundbar simultaneously produces a pumping effect that sounds worse than the original problem.
If you only watch at low volume in the evening, night mode is the single most effective change available. It is designed for exactly that: hearing dialogue clearly without waking the house during action scenes.
Fix 2: stop format switching
A large share of sudden volume changes happen when the audio format changes, for example moving from a stereo advert to a surround programme, or from one app to another. Each change forces the audio chain to renegotiate, and levels shift.
Setting each source device to output PCM stereo, rather than passing surround formats through, eliminates the switching. You lose surround on systems that can use it, and on a two-channel soundbar or TV speakers you were never getting it anyway.
If you do have a surround system, the alternative is to fix the output format rather than letting it follow the content, which achieves the same stability.
Fix 3: check where the volume is actually controlled
In a typical setup there are at least three volume controls: the source device, the television, and the soundbar. If the source device’s volume is low and the soundbar is turned up to compensate, everything becomes inconsistent, because the source’s level varies between apps.
Set the source device to its maximum or reference level, set the television’s output to fixed if it offers the option, and control everything with the soundbar. That gives you one control that behaves predictably.
Fix 4: per-app settings
- Streaming apps often have their own audio setting, offering stereo or surround. Choosing stereo makes levels more consistent on a simple system.
- Some apps include a loudness or night setting of their own, which is worth finding.
- Games consoles have a chat and game balance plus an overall audio format setting, and both affect perceived level.
- Live channels and catch-up apps from the same broadcaster frequently differ, which is worth knowing before you conclude something is broken.
Fix 5: adverts specifically
Adverts are mixed to sit at the top of the permitted loudness range at all times, while programmes vary within it. Regulations in most countries prevent adverts being genuinely louder than programming, and they can legally be consistently loud where the programme is not.
Dynamic range compression handles this well. So does muting, which remains the most reliable solution ever devised.
Turning on every available audio enhancement at once makes things worse. Volume levelling on the TV, night mode on the soundbar and an app’s own normalisation all fighting each other produce audible pumping, where the volume visibly rises and falls. Pick one and turn the others off.
Fix 6: the speakers themselves
Part of the dialogue problem is physical. Television speakers fire backwards or downwards and lack a dedicated centre channel, so speech competes with everything else. A soundbar with a genuine centre channel makes dialogue clearer at lower volume, which reduces how much you need to adjust between quiet and loud scenes in the first place.
If you are already using a soundbar and dialogue is still difficult, check whether it has a dialogue mode, and reduce the bass, which masks speech frequencies more than people expect.
Why are adverts louder than programmes?
They are mixed to sit consistently at the top of the permitted loudness range, while programmes vary. Regulations prevent them exceeding the limit, and they do not require them to be quiet.
What does night mode actually do?
It compresses the dynamic range, raising quiet sounds and lowering loud ones. This makes dialogue audible at low volume without effects becoming startling.
Should I use PCM or surround output?
PCM if your system is a TV or a stereo soundbar, because it avoids format switching and level jumps. Surround if you have a system that genuinely uses the extra channels.
Why is one streaming app quieter than another?
Services normalise to different loudness targets, and their apps handle output differently. Setting a consistent output format on the source device reduces the difference.
Will a soundbar fix quiet dialogue?
Usually yes, because a dedicated centre channel separates speech from the rest of the mix. Combine it with a dialogue mode and slightly reduced bass for the clearest result.
The short version
Turn on one dynamic range control, on whichever device is doing the amplifying, and turn the others off. Set source devices to PCM to stop format switching. Fix the TV’s output level and control volume in one place. Then use the dialogue mode and reduce the bass, which together make speech clear enough that you stop reaching for the remote.
