Connect Soundbar to Toshiba Fire TV & Fix Audio Delay

This guide walks you through connecting a soundbar to your Toshiba Fire TV using the best method for your setup, then shows you how to eliminate any audio delay (lip-sync issues) that often appears after the connection. You’ll need your soundbar, its remote or buttons, and the correct cables for your model—most likely an HDMI cable or an optical cable.

What You’ll Need

• Your soundbar and its power cable
• An HDMI cable (preferably HDMI 2.0 or higher) if your soundbar has HDMI ports
• An optical (TOSLINK) cable if your soundbar lacks HDMI
• The soundbar’s remote control (or access to its physical buttons)
• The Toshiba Fire TV remote

Step-by-Step

1. Identify your soundbar’s inputs. Check the back or side of the soundbar for HDMI ports (usually labeled HDMI IN or HDMI OUT/ARC), an optical port, or both. If you have an HDMI ARC/eARC port on both the TV and soundbar, that’s the best connection.
2. Connect via HDMI ARC (recommended). Plug one end of the HDMI cable into the soundbar’s HDMI OUT/ARC port and the other into the TV’s HDMI ARC port (often labeled HDMI 1 or HDMI 2 with “ARCâ€� next to it). If your soundbar has multiple HDMI inputs, use the one labeled ARC or OUT.
3. Connect via optical (if no HDMI). Insert the optical cable into the soundbar’s OPTICAL IN port and the TV’s OPTICAL OUT port. Remove the protective caps from both ends first.
4. Power on both devices. Turn on the soundbar and the TV. The soundbar should automatically switch to the correct input, but if not, press the Source/Input button on the soundbar until it shows HDMI or Optical.
5. Set the TV’s audio output. On your Toshiba Fire TV, go to Settings (gear icon) → Display & Sounds → Audio output. Choose HDMI ARC if you used HDMI, or Optical if you used the optical cable. If you see Digital audio out, select Auto or Pass-through.
6. Test the sound. Play a video on the Fire TV. You should hear audio from the soundbar. If not, double-check the input on the soundbar and the TV’s audio output setting.
7. Fix audio delay if you notice it. If the sound is out of sync with the picture, go back to Settings → Display & Sounds → Audio output and look for Audio delay or Lip sync. Adjust the slider (usually in milliseconds) until the sound matches the picture. Start with +50ms and fine-tune.
8. If no delay setting exists on the TV, use the soundbar’s delay setting. Many soundbars have a dedicated button or setting for audio sync (sometimes called “AV Syncâ€� or “Lip Syncâ€�). Press the Soundbar’s remote’s “Soundâ€� or “Settingsâ€� button and look for a sync option.

Common Mistakes

• Plugging HDMI into the wrong port. The HDMI cable must go into the port labeled ARC on the TV, not just any HDMI port. If you use a non-ARC port, audio won’t return to the soundbar.
• Using an optical cable when the TV has no optical output. Some newer Toshiba Fire TVs only have HDMI ARC. Check the TV’s manual or look at the ports before buying cables.
• Not switching the soundbar’s input. Even after connecting, the soundbar may stay on Bluetooth or another input. Press the Source button until the correct one is selected.
• Ignoring the TV’s internal speakers. If the TV’s speakers are still on, you might hear echo or delay. In Audio output, select the soundbar option to disable the TV speakers.
• Assuming all HDMI cables are the same. Older HDMI cables may not support ARC or the bandwidth needed for high-quality audio. Use a cable labeled “High Speedâ€� or “Premium High Speed.â€�

Tips

• Use HDMI ARC over optical whenever possible. ARC supports higher-quality formats like Dolby Digital Plus and allows you to control the soundbar volume with the Fire TV remote. Optical only carries compressed 5.1 at best.
• Update your Fire TV software. Go to Settings → My Fire TV → About → Check for Updates. Newer firmware often fixes audio sync bugs.
• Try a different HDMI port on the TV. Sometimes the ARC port is the second HDMI port, not the first. Check the label on the TV.
• If you use a soundbar with multiple HDMI inputs, connect your streaming device (like a Fire TV Stick) to the soundbar’s HDMI IN. This can reduce delay because the TV doesn’t need to process the audio separately.
• Set the audio format to “Autoâ€� or “Dolby Digital.â€� In the TV’s audio settings, avoid “PCMâ€� if you have a soundbar that supports Dolby, as PCM can cause a slight delay.

Troubleshooting

No sound at all:

• Check that the soundbar is on and the correct input is selected.
• Verify the TV’s audio output is set to the correct option (HDMI ARC or Optical).
• Try a different HDMI cable or optical cable. Cables can be faulty even if they look fine.
• Restart both the TV and the soundbar by unplugging them for 30 seconds.

Audio delay persists after adjusting settings:

• If you used optical, try switching to HDMI ARC if your TV supports it—ARC often has lower latency.
• Check if your soundbar has a “Gameâ€� or “Movieâ€� mode that adds processing delay; switch to a standard mode.
• Disable any “surroundâ€� or “virtualizerâ€� effects on the soundbar, as these can introduce delay.
• If the delay is consistent, try setting the TV’s audio output to “PCMâ€� instead of “Auto.â€� This sometimes reduces delay at the cost of losing surround formats.

Soundbar works but TV remote doesn’t control volume:

• Ensure you’re using the HDMI ARC connection, as optical doesn’t support CEC.
• Go to Settings → Equipment Control → Manage Equipment → Soundbar and follow the on-screen setup to pair the remote.
• If that fails, try a universal remote or use the soundbar’s own remote.

Audio cuts out intermittently:

• Check for loose cable connections.
• Try a different HDMI port on the TV.
• Update the soundbar’s firmware if it has a USB port or app.

Frequently Asked Questions

Q: Can I connect a soundbar to a Toshiba Fire TV without an HDMI ARC port?
A: Yes, if your TV has an optical output, you can use an optical cable. If it has neither, you can use a 3.5mm headphone jack (if the soundbar has one) or a Bluetooth connection, but those may have more delay and lower quality.

Q: Why is the audio delay worse on some apps than others?
A: Different streaming apps handle audio differently. Some apps may output audio in a format that the TV or soundbar processes with more latency. The TV’s audio delay setting is global, so you may need to adjust it per app or use the soundbar’s own sync feature.

Q: Does the length of the HDMI cable affect audio delay?
A: No, cable length does not cause noticeable audio delay in typical home setups (under 10 meters). Signal quality can degrade with very long cables, but latency is not a factor.

Q: Can I use Bluetooth to avoid audio delay?
A: Bluetooth often has more delay than wired connections, especially with older Bluetooth versions. If you must use Bluetooth, try a soundbar that supports aptX Low Latency and ensure the TV’s Bluetooth version is compatible.

Q: What is the best audio format setting for a soundbar?
A: Set the TV’s audio format to “Autoâ€� or “Dolby Digitalâ€� if your soundbar supports it. This allows the TV to pass through compressed surround sound without extra processing. If you experience delay, try “PCMâ€� as a fallback.

Q: Why does the soundbar work fine with the TV’s built-in apps but not with an external device like a Fire TV Stick?
A: The Fire TV Stick may be outputting a different audio format. Go to the Fire TV Stick’s settings (if it’s plugged into the TV) and set audio to “Dolby Digitalâ€� or “Auto.â€� Also, ensure the HDMI cable from the Stick to the TV is high-speed.
