Sony Bravia voice assistant not responding — remote mic, “Hey Google” & built-in MIC issues

Technician avatar Technician
Hey! We’ll figure out why your Sony Bravia voice assistant is not responding and get voice search working again without sending the TV to a service center.
Quick questions so we don’t guess:
• Exact TV model and year (Sony Bravia Android TV or Google TV, e.g. X90J, A80J, X85K, etc.)?
• Are you pressing the Google Assistant / mic button on the remote, using hands-free “Hey Google / OK Google” with the built-in MIC, or both?
• What happens when you try: nothing at all, a “voice search not available” message, or “Something went wrong. Try again”?
• Is the microphone icon on the home screen greyed-out, crossed-out, or do you see “Mic is off” on your Sony TV?
The more detail we have, the easier it is to fix a Bravia voice assistant / Google Assistant not working problem step-by-step at home.
Customer
It’s a Sony Bravia X90J on Google TV. The voice assistant stopped responding recently. When I press the mic button on the remote, sometimes nothing happens, other times it briefly shows the Assistant bar and then says “Something went wrong, please try again”. Saying “Hey Google” to the TV doesn’t do anything at all. The little microphone icon on the home screen looks grey or disabled. Wi-Fi and apps are working fine otherwise.

Got it — that’s a very typical Sony Bravia voice assistant not responding pattern.
On Bravia Android TV / Google TV a few things can silently break voice control:
• The remote microphone isn’t paired properly over Bluetooth, or its batteries are weak.
• The built-in MIC hardware switch on the TV body is set to Off, so hands-free “Hey Google” never hears you.
• Google Assistant / voice search got disabled after a system update, privacy change, or child profile switch.
• Time, region or network settings are off, so Google’s servers reject the request even though regular apps still stream fine.

We’ll:
1) Confirm the TV is online and signed into a Google account.
2) Re-enable Google Assistant & microphone permissions on your Sony Bravia.
3) Re-pair the remote so the mic button starts working again.
4) Check and turn on the Built-in MIC / “Hey Google” switch so hands-free commands respond.
If needed, we’ll also clear voice-related app data and update the TV — all DIY, no technician visit.
Customer
The TV is on Wi-Fi and I’m signed into my Google account. Streaming apps work. When I long-press the voice button on the remote, I sometimes see “Check your network connection” even though YouTube plays fine. The “OK Google / Hey Google” hands-free thing has never really worked reliably. I’m not sure where the built-in mic switch is on this Sony TV.
Technician avatar Technician
Perfect, let’s lock in the basics first so we know the Sony Bravia voice control has everything it needs.
Step 1 — Confirm network & time (Android TV / Google TV)
1) On the TV, go to Settings > Network & Internet and make sure your main Wi-Fi is connected with a strong signal (not a guest network).
2) Go to Settings > System > Date & time and enable “Automatic date & time” and “Automatic time zone”. Incorrect time can make Google Assistant say “Something went wrong”.

Step 2 — Make sure Google Assistant is actually enabled
1) Open Settings > Accounts & sign-in > Google and confirm you’re signed in.
2) Go to Settings > System > Google Assistant (or “Apps > Google Assistant” depending on your Bravia menu).
3) Accept any privacy / data prompts and make sure “Google Assistant” is set to On and the language is one you speak (e.g. English).
After this, try the voice button once more. If it still doesn’t respond reliably, we’ll focus on the remote microphone not working part next.
Customer
Time and time zone were already automatic. Google Assistant was enabled, I accepted the data prompts again just in case. Still, when I press the mic button, sometimes it doesn’t show the listening overlay at all. Other times it pops up but doesn’t hear me, then gives the same “Something went wrong” message. Batteries in the remote were changed a couple of months ago.
Technician avatar Technician
That’s classic Sony Bravia remote microphone not working properly — the TV still talks to the remote for buttons, but the Bluetooth voice pairing is flaky.
Step 3 — Re-pair the Sony voice remote
1) Stand about 1-2 meters from the TV.
2) On the TV go to Settings > Remotes & Accessories (or “Remotes & Accessories > Bluetooth”).
3) Highlight your Sony voice remote, choose Unpair / Forget and confirm.
4) Remove the remote’s batteries for 10–15 seconds, then put them back in.
5) Press and hold the buttons the on-screen instructions mention (often Home + Back, Home + Vol- or similar) until the TV shows “Pairing remote”. Let it finish.
6) When it says paired, press the Google Assistant / mic button and speak a simple command like “open YouTube”.

If voice search now responds via the remote but “Hey Google” still doesn’t wake the TV, the issue is likely the built-in MIC or its privacy settings — we’ll fix that next.
Customer
Re-pairing helped a bit: the Assistant overlay now appears every time I press the mic button and it heard “open YouTube” once. But the hands-free part still doesn’t work — I can say “Hey Google” right in front of the TV and nothing happens. I also noticed a tiny switch under the screen but I never touched it.
Technician avatar Technician
Yep, that tiny switch is the star of the show here. On many models, if the Built-in MIC switch is Off, hands-free “Hey Google” on Sony Bravia will never respond no matter what the software says.
Step 4 — Turn on the Built-in MIC & hands-free detection
1) Find the small Built-in MIC switch on the TV body (often under the front bezel or on the side). Slide it to On.
2) On the TV, go to Settings > System > Microphone / Built-in MIC (or “System > Voice & Assistant”).
3) Make sure “Built-in MIC” is set to On and that any “Hands-free” or “Hey Google” options are enabled.
4) You may be asked once more to accept Google Assistant terms for hands-free mode — choose Yes / I agree.
5) Now on the home screen, wait a second and then say clearly: “Hey Google, what’s the weather?” while facing the TV.

If the built-in MIC still doesn’t respond after that, we’ll treat it like a built-in microphone not responding to Hey Google issue and refresh the Google / Assistant apps on the TV.
Customer
The switch was actually Off. I turned it on and enabled the Built-in MIC and hands-free options in the settings. Now, when I say “Hey Google”, the Assistant bar shows up, but about half the time it says “Something went wrong” or “Try again in a few seconds”. It’s better than before, but still not really usable.
Technician avatar Technician
Great, we’ve confirmed the hardware MIC works — now we just need to stabilise the Google Assistant services on your Sony Bravia.
Step 5 — Refresh Google / Assistant components on the TV
1) Go to Settings > Apps > See all apps.
2) Find Google, Google Play services, and (if present) Android System Intelligence / Speech services.
3) For each one, open it and choose: “Force stop” → “Clear cache” (leave “Clear data” for last resort).
4) Return to Settings > Apps > See all apps > Show system apps, and clear cache for “Voice Input” or “Speech Services”.
5) Then go to Settings > System > About > System software update and install any pending Sony / Google TV updates.

After the reboot, test both:
• Long-press the mic button on the remote and ask “open Netflix”.
• Say “Hey Google, volume 15” using the built-in MIC.
If the Sony Bravia voice assistant still fails intermittently, we’ll check for region or profile limitations and talk about when a factory reset makes sense.
Customer
After clearing cache and updating, the remote voice button works well now for searches and opening apps. “Hey Google” also responds most of the time, except on some HDMI inputs it says voice search isn’t available. I also sometimes see that voice commands won’t control certain apps, just the TV volume or input.
Technician avatar Technician
That’s normal behaviour. A few quick notes so you know what to expect from the Bravia voice assistant:
• On some HDMI inputs, voice search is limited to TV functions (like input or volume) and can’t search inside whatever device is connected.
• Not all apps support full voice navigation — in some, Google Assistant can only open the app or search basic content.
• If you switch to a kids / restricted profile, assistant features and personalized results may be reduced or disabled.

Best practices so Sony Bravia voice control stays reliable
• Use a normal Google / main profile for TV watching rather than a restricted one.
• Keep the TV on a stable home network and avoid captive portals / hotel Wi-Fi.
• Occasionally reboot the TV (long-press Power on the remote > Restart) to clear temporary voice search glitches.
• Don’t cover the built-in MIC area with soundbars or decorations, and speak from 1–3 meters away in a reasonably quiet room.
This keeps “Hey Google not responding on Sony Bravia” issues from coming back every few days.
Customer
That makes sense. If the voice assistant stops working completely again in the future, should I just repeat these steps, or is it worth doing some kind of reset on the TV or remote to fix Google Assistant on Sony Bravia?
Technician avatar Technician
Good question. You don’t want to factory-reset every time, but there are two “last resort” options if the Sony Bravia voice assistant completely stops responding again:
Option A — Reset the voice remote
• Remove the batteries for 30 seconds, then re-insert them.
• Use the on-screen instructions in Settings > Remotes & Accessories to pair it as a new remote.
• If your model supports it, perform a remote reset (often holding Back + Home or another combo until the LED flashes, then re-pair).

Option B — Full TV factory reset (only if nothing else works)
• Go to Settings > System > Reset / Factory reset and follow the prompts, or use the physical power/reset buttons as per Sony’s instructions.
• This wipes apps and settings but often resolves deep Android TV / Google TV assistant glitches that normal resets can’t fix.

Before taking Option B, it’s worth double-checking the built-in MIC switch, Google account, and network again. If you ever feel stuck, you can open a live chat and we’ll walk through the exact steps for your Bravia model together.
Customer
After turning on the mic switch, re-pairing the remote, and clearing the Google app cache, everything is working now. Both the remote voice button and “Hey Google” respond properly on my Sony Bravia Google TV. I’ll keep your reset steps in mind if it acts up again. Thanks for helping me fix it without calling a technician!
Technician avatar Technician
Summary: when a Sony Bravia voice assistant is not responding, start by checking network and Google Assistant settings, then re-pair the Sony voice remote microphone. Turn on the Built-in MIC switch and hands-free “Hey Google” options if you want voice activation without touching the remote. If problems persist, clear cache for Google and voice services, update the TV, and only then consider a remote or TV reset. Not sure which menu your Bravia or Google TV uses? Open the chat and an expert will guide you through it step by step.

Quick answer: the accepted fix

Accepted fix when the Sony Bravia voice assistant is not responding: confirm the TV is online and signed into Google, then re-pair the voice remote in Remotes & Accessories so the mic button works again. Turn on the Built-in MIC switch on the TV body and enable hands-free “Hey Google” in settings. Finally, clear cache for Google / voice apps and install any pending Sony Bravia Android TV or Google TV updates to stabilise voice search.

Why Sony Bravia voice assistant stops responding (Android TV / Google TV)

Most Sony Bravia voice assistant not responding issues come down to a few common causes: the remote microphone losing its Bluetooth pairing, the Built-in MIC switch being turned off, or Google Assistant being disabled or confused after an update. If the TV time or region is wrong, the cloud side of Google Assistant on Bravia can fail even though video apps still work. On Google TV, switching to a restricted or kids profile can also limit what voice search can do, making it seem like the Bravia voice control is not working even though the microphone hears you.

How to test if Sony Bravia voice control is really fixed

After you adjust settings, give your Sony Bravia voice assistant a proper test. From the home screen, press the mic button on the Sony remote and ask it to open a few different apps and search for shows. Then try hands-free commands like “Hey Google, volume 15” or “Hey Google, open YouTube” using the built-in microphone. If the voice assistant responds quickly, shows the correct results, and no longer throws “Something went wrong” errors, your Bravia voice search is stable. If it only fails on certain HDMI inputs or apps, the issue is usually app or device limitations, not the TV’s microphone or Google Assistant itself.

Sony Bravia voice assistant not responding — quick troubleshooting tips

Most cases are fixed by pairing the remote again, enabling the MIC switch and refreshing Google Assistant.

Quick path: confirm the TV is on a stable home network, then re-pair the Sony Bravia voice remote so the mic button uses Bluetooth, not just infrared. Turn on the Built-in MIC switch and hands-free “Hey Google” options for models that support always-listening voice control. In Settings > Apps, clear cache for Google, voice input and related services, then run a system software update. If the voice assistant on Sony Bravia still won’t respond, a remote reset or, as a last resort, a TV factory reset usually clears deeper Android TV / Google TV glitches.

FAQ

Why is my Sony Bravia voice assistant not responding when I press the mic button?

If the Sony Bravia voice assistant doesn’t react to the remote’s mic button, the voice remote may not be paired via Bluetooth, its batteries may be weak, or Google Assistant may be disabled. Re-pair the remote under Settings > Remotes & Accessories, confirm the TV is connected to the internet and signed into Google, and make sure Google Assistant is turned on with a supported language.

How do I turn on Hey Google / OK Google on my Sony Bravia TV?

On supported Sony Bravia Android TV or Google TV models, turn on the Built-in MIC switch on the TV body, then go to Settings > System > Microphone or Voice & Assistant. Enable the built-in microphone and hands-free “Hey Google” options, accept the Google Assistant privacy prompts, and pick your language. When set up correctly, you can say “Hey Google” from the home screen without touching the remote.

Do I need internet for Sony Bravia voice search to work?

Yes, most Sony Bravia voice search and Google Assistant features require an active internet connection, because your commands are processed in the cloud. Some basic TV controls like volume or input switching can work locally, but content searches, weather, and smart home control all need the TV to be online with the correct time and region.

When should I reset my Sony Bravia TV or remote to fix voice control?

Try simpler steps first: re-pair the remote, turn on the built-in MIC, and clear cache for Google / voice apps. If the voice assistant on your Sony Bravia still won’t respond, you can reset the remote and pair it again. A full TV factory reset should only be used as a last resort when other troubleshooting fails, because it removes installed apps and custom settings.
