Samsung TV screen mirroring no sound is usually caused by a wrong audio output setting or a mismatch between the TV’s speaker selection and the casting device. Start by checking that your Samsung TV is set to the correct sound output (TV speakers vs Bluetooth/receiver) and that the mirroring source’s audio is enabled. If those settings are right, the fastest fix is to restart the mirror connection and update both the TV software and the casting app.
Fix silent Samsung TV screen mirroring by setting the TV’s Sound Output to the correct speaker/device, then verify the phone/PC is actually sending audio to the TV. If that’s correct, the next most common causes are Bluetooth audio routing conflicts and HDMI‑CEC/Anynet+ behavior that misdirects audio while the video mirror still looks fine.
If your Samsung TV shows the mirrored screen but there’s no sound, fix the audio output first—set the TV’s sound to the correct speaker/device for mirroring. Then check the mirroring source’s audio settings and whether HDMI-CEC/TV speaker mode is conflicting. This guide walks you through the most common causes and the exact settings to verify.
This applies when screen mirroring works visually (phone/PC displays on the Samsung TV) but audio stays silent. It’s also typical after updating apps/OS, switching Wi‑Fi networks, or using a different mirroring method (Smart View/AirPlay/Chromecast-compatible apps).
This guide is for Samsung TV owners who get “screen mirrors but no audio” on 2024–2026 software updates and after changing casting methods, accessories, or network conditions. It’s also useful if you don’t want to do a disruptive full factory reset and would rather verify audio routing step-by-step on both the TV and the source device.
Step 1: Confirm the TV is using the right audio output
Samsung TV mirroring usually fails silently because the TV is routing audio to the wrong output device—so fix that first. On your Samsung TV, confirm the Sound Output (and any “TV speaker” mode) matches where you want audio to play.
If your mirrored video plays but audio is silent, the TV’s Sound Output setting is the first place to verify because it determines the active audio path on the Samsung TV. Samsung TV user manuals / support documentation on Sound Output
ARC and eARC are audio return pathways over HDMI, so selecting the wrong HDMI audio return mode can result in “no sound” even when the picture mirrors correctly. HDMI Licensing, HDMI ARC/eARC documentation
Start by opening your Samsung TV menu and going to:
– TV Settings → Sound Output (wording varies by model)
– Look for options such as TV Speakers, Bluetooth audio, Optical, or an HDMI audio device (often labeled by connected receiver/soundbar)
Then choose the correct output:
– If you want audio through the built-in TV speakers, set it to TV Speakers (or the equivalent internal speaker option).
– If you use a soundbar/AV receiver, set it to that external device as the TV’s selected Sound Output.
What to look for on Samsung TV (common misroutes)
1. Inactive Bluetooth output
Samsung TVs can keep a previously paired Bluetooth audio target. The TV may show Bluetooth as an output even if the headphones/speaker aren’t actually playing audio right now. In that scenario, the mirror picture can work while the audio goes nowhere.
2. External speaker selection not matching the current connection
If you recently changed HDMI ports, switched a soundbar input, or updated your receiver firmware, the TV may still be targeting the old HDMI audio route.
3. TV speaker mode vs. external audio mode conflict
Some Samsung setups use “TV speaker” behaviors alongside HDMI-CEC control (Anynet+). If those features disagree, audio can be muted or diverted even though the mirror visually updates normally.
Quick validation
After setting the correct Sound Output, play a known-audio test:
– Open YouTube on the source device and mirror again
– Or play a system sound (notification tone/short audio clip) from the same source app
If you suddenly hear audio on the Samsung TV after changing Sound Output, you’ve already solved the core issue.
Step 2: Check the mirroring source audio settings
Samsung TV audio can stay silent even when the TV output is correct if the phone/PC is sending audio to the wrong place. Next, verify the mirroring source’s media volume and its audio output device selection for casting/mirroring.
Casting/mirroring apps often treat “video mirroring” and “audio routing” separately, so you can see the display while audio remains directed to another device. Apple / Google / Samsung platform documentation for screen casting and audio output behavior
On Bluetooth-enabled devices, the most recent audio target can remain selected, which can cause mirrored audio to go to a different output even though the Samsung TV updates its display. Bluetooth SIG general behavior and OS audio routing documentation
On your phone/PC:
1. Unmute and raise media volume
– Ensure the app you’re mirroring isn’t muted.
– Confirm media volume isn’t turned down to zero on the source device (not just the TV).
2. Confirm the app audio is actually playing on the source
Try a simple audio test:
– Open a different app (e.g., YouTube) on the source
– Play sound locally (without mirroring) to confirm audio works
3. Switch the casting audio output to the Samsung TV (if available)
Depending on OS and mirroring method, you may see an output device option such as:
– “Audio output: Samsung TV”
– “Cast audio to…”
– “Send sound to…”
If you see a toggle for audio vs. video behavior, make sure audio is included.
Practical examples by mirroring type
– Smart View (Samsung ecosystem): audio is usually handled through the TV audio path, but mismatched TV Sound Output can still block it.
– AirPlay-compatible mirroring: iOS/macOS may expose an output target—if audio points elsewhere, you’ll get silent mirroring.
– Chromecast-compatible apps: some apps can cast video while their audio routing is governed by the device’s casting profile.
If you recently changed OS/app versions (common in 2025–2026), re-check the source’s audio output picker—updates sometimes reset it.
Step 3: Disable conflicting audio features (Bluetooth + HDMI-CEC)
If Samsung TV output and source audio are correct but mirroring stays silent only during casting, conflicts are usually the culprit. Disable Bluetooth temporarily and review HDMI‑CEC/Anynet+ settings so the TV isn’t trying to “control” an audio device you can’t actually hear.
HDMI‑CEC (Consumer Electronics Control), implemented by Samsung as **Anynet+**, can automatically route control and audio behavior across HDMI devices, which may break expected audio routing during mirroring. Samsung Anynet+ / HDMI‑CEC support documentation
HDMI‑eARC was introduced with HDMI 2.1 (2020) to improve audio return and synchronization, so incorrect ARC/eARC routing can still cause “picture works, sound missing” scenarios on some setups. HDMI Licensing, HDMI 2.1 / eARC documentation
What to do (fastest isolation test)
1. Temporarily turn Bluetooth off on the TV
– Disconnect paired Bluetooth audio devices
– Or disable Bluetooth routing in TV settings
2. Re-test mirroring
– If sound returns immediately, Bluetooth routing was the conflict.
Review HDMI‑CEC / Anynet+ behavior
HDMI‑CEC (Anynet+) can do more than wake devices—it can influence which device “should” handle audio. Misalignment can happen when:
– Your soundbar/receiver supports CEC but has a different audio profile than expected
– You changed HDMI ports or devices
– Your TV update changed how it negotiates control/audio paths
In Samsung TV settings, look for options like:
– Anynet+ (HDMI‑CEC)
– HDMI Device Control
– Auto device power / audio device switching
To troubleshoot:
– Keep HDMI‑CEC enabled if your soundbar is working normally, but try a controlled test:
– Toggle the relevant HDMI‑CEC setting off temporarily
– Reconnect mirroring
Step 4: Restart the connection path (TV + source + mirroring)
When the settings are correct but audio still doesn’t appear, the connection negotiation may be stuck—especially after updates or network changes. Restart the full chain and reconnect mirroring from scratch.
Screen mirroring often renegotiates audio routes at connection time, so reconnecting from scratch can restore audio when a prior session established the wrong output target. Samsung Smart View / Apple AirPlay / Google Cast platform troubleshooting guidance
Switching networks (new SSID or router) can allow video mirroring while audio negotiation fails, so power-cycling the TV and source helps re-establish consistent media sessions.
Do this methodically:
1. Power cycle the TV
– Turn it off
– Wait for it to fully power down
– Turn it back on
2. Restart the mirroring source device (phone/PC)
– Close the mirroring/casting app fully, then reopen it
– If you can, restart the device (or at least toggle Airplane mode / Wi‑Fi off-on)
3. Reconnect mirroring from the start
– Start mirroring fresh (don’t just pause/resume)
– If the mirroring method has multiple modes, use the same one consistently (e.g., Smart View vs. a third-party casting app)
4. Confirm audio output again
– After reconnecting, quickly re-check TV Sound Output—some devices re-select outputs during reconnection.
Why consistency matters
Different mirroring methods can “advertise” different capabilities to the TV and OS (for example: audio-inclusive vs. video-only behaviors). If you switch methods mid-troubleshooting, you might fix one session while another still behaves differently.
Most common Samsung TV audio-output choices during mirroring (what they do)
| # | Sound Output option on Samsung TV | Active audio path | Common “No Sound” cause | Check priority |
|---|---|---|---|---|
| 1 | TV Speakers | Built-in TV driver | Audio routed internally but hidden by mismatch with Bluetooth/CEC | ★★★★★ |
| 2 | Bluetooth Audio Device | Bluetooth sink (headphones/speaker) | Paired device not connected, or audio goes “somewhere else” | ★★★★☆ |
| 3 | Soundbar / Audio Return via HDMI | HDMI (ARC/eARC) path | CEC/ARC negotiation fails after HDMI port changes | ★★★★☆ |
| 4 | Digital Audio Out (Optical) | Optical/TOSLINK receiver | Receiver expects different format or is muted/off | ★★★☆☆ |
| 5 | External Receiver (HDMI) | AV receiver over HDMI | TV still targets receiver audio route after switching sources | ★★★☆☆ |
| 6 | HDMI-CEC Controlled Device | Device chosen by HDMI‑CEC | CEC causes audio to “jump” to a device you didn’t intend | ★★★★☆ |
| 7 | No Bluetooth / Auto Output | Auto-selected output | Auto selection picks an output that’s silent or disconnected | ★☆☆☆☆ |
What can go wrong (common mistakes and edge cases)
Even after you follow the steps, a few edge cases can keep Samsung TV mirroring silent. The fastest way forward is to identify whether the issue is misrouted output, app/method behavior, or a negotiation problem caused by recent changes.
In HDMI and casting ecosystems, it’s common for video and audio handling to be negotiated separately, so “image present, audio absent” usually signals an audio-path selection problem rather than a display failure. HDMI Licensing / casting platform troubleshooting guidance
If a source device remembers an old Bluetooth audio target, it may continue routing mirrored audio away from the Samsung TV until the OS audio target is changed. Bluetooth SIG general connection and audio output behavior documentation
Common mistakes that look like “the TV is broken”
– You see the image but the source is outputting to a different device (common with PCs and phones that remember previous Bluetooth outputs).
– Multi-room/speaker casting on the source can override where audio goes, even if the TV displays correctly.
– Some mirroring methods may be video-only depending on app/OS behavior—in that case, switching mirroring method or using a built-in “audio” toggle may be necessary.
– If you recently changed network settings (new router/SSID), the connection can work for video while negotiating audio less reliably—reconnect helps.
– Model differences matter: Samsung menus and options vary, so if you don’t see a setting name exactly, use the closest matching category (Sound Output, External Speaker, or Bluetooth).
Pros/cons: swapping mirroring methods to restore audio
If the TV is fine but the mirroring method isn’t sending audio reliably in 2025–2026, switching methods can resolve it quickly.
| Mirroring method | Pros for audio reliability | Potential downside for “no sound” cases |
|---|---|---|
| Samsung Smart View | Uses Samsung-friendly routing and typically aligns with TV speaker output choices. | App updates can change whether audio is treated as “included” vs. OS-managed. |
| AirPlay-compatible mirroring | Often integrates audio into the display session when the output target is selected correctly. | If iOS audio target points elsewhere, you’ll still get silent video mirroring. |
| Chromecast-compatible apps | Some apps handle audio switching more predictably than OS-level mirroring. | Audio routing depends heavily on the app’s cast profile and OS audio selection. |
A quick reality check on “fixes”
– If disconnecting Bluetooth makes sound return, don’t keep Bluetooth changes permanently—you can re-enable it after you set the intended TV/BT audio output.
– If turning off HDMI‑CEC fixes audio but breaks device control, switch back and adjust only the audio-related behavior rather than leaving everything off.
Verdict / tip (what to try first, and who should skip certain steps)
Start with TV Sound Output and source audio output—those checks solve most “silent mirroring” cases quickly in 2026. Avoid heavy resets first: if you rely on paired Bluetooth audio or HDMI devices for everyday viewing, don’t disable CEC/Bluetooth long-term unless you’re troubleshooting.
| If this is happening | Try first | Skip / be cautious |
|---|---|---|
| Mirroring shows video, no audio | TV Settings → Sound Output → TV Speakers (or correct device) | Factory reset before verifying audio output paths |
| Audio fails only during mirroring | Disconnect Bluetooth + review Anynet+/HDMI‑CEC behavior | Leaving HDMI‑CEC off indefinitely if you depend on soundbar control |
| Sound returns after reconnecting once | Power cycle TV + source and reconnect mirroring from scratch | Changing multiple settings at once (harder to isolate the cause) |
You don’t need a factory reset in most “silent mirroring” cases because routing and negotiation failures are usually resolved by correcting Sound Output and reconnecting the session. Samsung support guidance and general casting troubleshooting best practices
If your Samsung TV is connected to a soundbar/AV receiver that you rely on daily, treat HDMI‑CEC/Anynet+ and Bluetooth as temporary diagnostic toggles and restore your preferred settings once audio returns. Samsung HDMI‑CEC/Anynet+ documentation
Quick scan checklist (save this)
– [ ] TV Sound Output set to TV Speakers (or correct external speaker)
– [ ] Bluetooth on TV/source not routing audio to an unseen device
– [ ] Source device media volume not muted; try a different app audio test
– [ ] Mirroring method uses the expected audio behavior (swap method if needed)
– [ ] Reconnect mirroring after power cycling TV + source
When mirroring video works, correcting the Samsung TV’s Sound Output is usually the quickest lever because it selects the actual audio sink before the next mirror session. Samsung TV documentation on Sound Output

Frequently Asked Questions
Why does Samsung TV screen mirroring have no sound, even though video connects?
This usually happens when your Samsung TV mirrors the display but the audio output is still set to another device or is muted. Check the TV by pressing the Volume button and confirming nothing is on mute. Then go to Sound settings and select the correct audio output source for mirroring (or switch back to the TV speakers temporarily).
How can I fix Samsung TV screen mirroring with no sound on my phone?
First, restart both your phone and the Samsung TV and try screen mirroring again. On your phone, confirm the media volume is up and that the audio isn’t routed to Bluetooth headphones or a different speaker. In the TV’s Sound settings, ensure the output is set correctly and not using a disconnected Bluetooth device.
What audio settings should I check on my Samsung TV when mirroring is silent?
Open Settings > Sound and verify the audio output is set to TV Speakers (or the device you’re actively using). If you use Bluetooth, disconnect or re-pair the audio device because mirroring can sometimes keep the TV output pointed to an unavailable device. Also check if any Sound Mode, HDMI/eARC, or external input settings are overriding the mirroring audio path.
Which mirroring app or connection method works best for Samsung TV screen mirroring with sound?
The most reliable option is Samsung’s built-in Smart View (if supported by your device) or using a direct casting/mirroring feature that explicitly routes audio to the TV. If Smart View still produces no sound, try switching from Wi‑Fi mirroring to casting from a specific media app (like YouTube/Netflix) where audio routing is handled more consistently. For troubleshooting, test both a different app and a different source device to isolate whether the issue is app-specific.
What should I do if I’m using HDMI or Bluetooth along with screen mirroring and there’s no sound?
If Bluetooth audio is connected, disconnect it and set the TV audio output back to TV Speakers or the correct connected soundbar/AV receiver. For HDMI setups, confirm the TV’s Sound Output is aligned with the active HDMI input (especially if you use eARC/ARC). After changing settings, restart the mirroring session so the Samsung TV re-negotiates the audio route properly.
