Here are the most common reasons why Marantz TV audio doesn’t work and what can be done to fix it.

1. Faulty HDMI Connection

As you have already seen, Marantz TV audio is directly connected to the HDMI port. If the cable leading from this slot to the TV is faulty, or if the port is damaged itself, the audio system will not work. 

Similarly, if there is a faulty HDMI control setting or it’s not accurate on the TV system, you will not get the perfect audio.


All you can do here is some manual checkups. And if you detect any problem, you have to handle it appropriately. Here’s how,

  • Make sure the HDMI connectors are in fine condition
  • See if the audio output is set to the AV amplifier on the TV
  • If you are using speakers, go to the HDMI setting on the TV menu and set “HDMI Audio Out” to the “AVR” setting. In case you want the output from the TV, select “TV” instead of “AVR”.

Now there shouldn’t be the issue of faulty HDMI anymore.

2. eARC Is Required

eARC-compatible television audio may not give output from the connected speaker. This usually happens if the eARC setting is not accurate. Apart from this, there are no software issues involved.


You can easily fix the problem with eARC in the following way,

  • Adjust the eARC setting according to your Marantz TV user manual
  • Set the input source to “TV Audio”   
  • Remove the HDMI cable, and restart the TV before plugging it in again.

Now, this should get your TV audio back to work.

Your TV audio system can be damaged due to several causes. It can be bad wiring or the accumulation of excessive dust. Whatever the reason may be, you need to take immediate action. 


Here you have to make sure the speaker is securely placed, and totally clean. You can ensure this in the following way,

  • Closely observe if the wiring is broken
  • In case of faulty wiring, replace the wire
  • Take a hand-held vacuum cleaner and set it on a low setting before applying on the speaker

This whole process may sound simple but in reality, this can be quite complicated. For this reason, it is recommended you take professional help for this problem.
