3. TV & Faulty Output Device’s Connection

After connecting your TV to the output devices like external speakers, and headphones, the internal sound bar on your TV becomes muted.

Your Toshiba TV audio output not working because you connect your device to the defective RCA Stereo, SCART, AUX, Digital Coax, VGA optical, or any wireless gadgets.


Check for the faulty output device & wireless gadget’s connection with your TV. Then disconnect the defective output device and your TV’s sound will function again.

4. Channel Experiencing Problems

Your Toshiba TV audio is out of sync because a particular channel in your TV is experiencing a sound problem.

Your Toshiba TV channel can experience troubles mainly for the following reasons:

  • Fault with the antenna
  • Weak or loose cable connection
  • A particular channel is not getting a signal or not streaming
  • Broadcast station’s signal transmission error


When a particular channel stops producing sound, you should try different channels and wait until the sound becomes restored. Resolve a specific TV station’s audio problem following the ways below:

  • Check and replace the faulty antenna and weak cable
  • Tighten the cable connection
  • Wait to restore the signal of a particular channel

6. TV Or External Device’s Faulty Speakers

Another reason your Toshiba TV sounds out is your TV or its external device’s defective speakers. Whenever you insert the headset or any other audio output in your TV, the unit’s speaker becomes dumb. 

external device's faulty speakers

Your TV or other device’s speaker can become defective due to mechanical failure, power surge, TV overheating, etc.  


Hook your TV’s external audio system to another device to check whether its internal speakers are working or not. Again check your TV’s internal speakers. Connect the headphone to your TV, and if your TV produces sound perfectly, that means your TV’s internal speaker is faulty. 

Replace the malfunctioning speakers and ensure your TV is not overheating or going through the power surge hitch.

7. TVs Turned Off Internal Speakers

Your Toshiba TV’s smart features allow you to turn on/off your TV’s built-in speakers. However, your Toshiba fire TV audio output is not working because, by mistake, you may turn off your TV’s internal speakers.


Check your TV’s internal speaker’s setting and enable it if it is in a turned-off position. For turning on your TV’s internal speakers, follow the easy steps below:

  • Using your TV remote, go to your TV’s Main Menu
  • Now select the options Audio < Speakers
  • Set the speaker status ON by pressing your remote’s Enter button.

8. Active Secondary Audio Protocol

For non-native cable TV users, Toshiba TV’s feature is the Secondary Audio Protocol (SAP). SAP features enable non-native users to enjoy the same channel in their own language rather than English.

However, when you turn on this SAP setting, your TV can stop producing sound because this feature is not available in all broadcasting channels. Or sometimes you can turn on this feature accidentally.


Check your TV’s SAP feature setting. If it is enabled, you need to disable this feature following the ways below:

  • Check your TV remote to find out the SAP or MS or Audio button, and then turn it off.
  • If your remote won’t have this labeled button, then pressing the remote, go to your TV’s Settings or Main Menu.
  • Go to the Sound option and then navigate to the SAP, MS, or Audio option. Then turn off these options.
  • If the SAP option is unavailable, find the MTS option and change this to the Mono or Stereo option.

Note: If you still fail to find the SAP option, go through your Toshiba TV user manual and find the options.

9. Faulty Cable Connection

Your Toshiba TV mainly receives data and power through cables. Now, if the cables are defective, your TV will also go through different problems.

 faulty cable connection

The defective audio cable causes your Toshiba TV no sound. Your TV cable has become bad mainly for the following reasons:

  • The HDMI cable is not correctly and securely attached to your TV and source device’s end
  • Inserting the A/V cable in the wrong port
  • The damaged, broken, or faulty cable itself
  • Loosely connected cable at the TV’s port and thus your TV lost connection
  • Only the S-Video cable is connected to your TV.


Whether the malfunctioning cable is responsible for your Toshiba TV’s Audio out or not, find it disconnects your TV’s all cord connections.

Wait 5-10 minutes, then reconnect the cables to your TV. This will reset your TV’s cable connection and drain the power.

But still, if your TV doesn’t produce sound, then you should follow the solutions below:

  • Ensure the HDMI cable is properly and securely attached to your Toshiba TV and the source device’s end.
  • Insert the A/V cable in the correct port
  • Replace the broken, damaged, or bad cable
  • Make sure your TV receives the perfect signal and tighten the cable connection on your TV’s port.
  • S-video cable supports the video signal only. Thus connect a separate audio cable to your TV so that your TV receives the Audio.

10. Improper TV Input Setting

Your Toshiba TV fails to receive the source signals perfectly because of improper or wrong input settings. And thus your Toshiba TV sound output is not working, but your TV can display the picture.

improper tv input setting

TV can’t receive the audio signal from the wrong source because data doesn’t exist in this source.


Check and change your Toshiba TV’s input to the correct source like the AUX, SAT, DVD, or Cable network, or on which source you rely.

And your Toshiba TV sound out-of-sync problem will disappear when it will receive the proper data and signal from the correct source.

12. Wrong “Audio Out” Variable Selection

When your Toshiba TV’s Audio Out jack connects to the external audio equipment, you can select the fixed or variable Audio Out feature.

Selecting the FIX Audio Out feature means your TV’s volume setting does not affect your TV.

Moreover, you have to adjust the audio equipment’s sound level using the equipment’s volume control if you select the FIX feature. Thus, your TV’s sound will not work.


Select the correct Audio Out feature and set the Audio Out to Variable. By selecting the Audio out variable feature, you can use the audio equipment or TV’s volume control to adjust the audio equipment’s sound level. 

For selecting the Variable Audio output, follow the quick steps below:

  • Press your TV remote’s Menu button
  • Now go to the Audio Menu
  • Highlight the option “Audio Out.”

Your Toshiba TV will smoothly perform and produce the best sound only when your TV receives the 20 dB audio and video signal level. Lower signal in TV distorts your TV’s image and sound. 

However, your TV’s signal strength becomes lower mainly of a faulty antenna, signal interference, or loose cable connection.


Monitor your Toshiba TV’s signal strength and sort out your TV’s Audio hitch by following the ways below:

  • Check your TV’s antenna connection, and replace the faulty antenna/cable box

You are experiencing your Toshiba TV with no audio issue due to a non-functioning motherboard.

 main board malfunction

Due to the faulty main board, your TV fails to receive the peripheral device’s signal like the disc player, sat box, cable box, PlayStation, etc. Your TV’s main board stops functioning mainly for the following causes:

  • Power surge or electricity frequency variation
  • Board’s faulty internal components
  • The mainboard is receiving higher or lower power due to a faulty electrical outlet
  • Bad resistors
  • Blown capacitors

  • Make sure the main board is receiving power properly

16. Turned Off Digital Audio Format

Your Toshiba TV stops producing sound because of the inactive digital audio format. When you connect your TV and home theater, sound bar, or external speaker using the digital optical cable, you need to turn on this audio format.


Check and turn on the Digital Audio Format on your Toshiba TV using the steps below:

  • Go to the Sound Menu on your TV. Then press and highlight the “Digital Audio Format” feature
