You’re trying to play some video or audio content via USB, PC, HDMI, or any other device but the audio isn’t playing on your TV due to an unsupported audio format?
There’s no need to worry, this isn’t a major issue and happens when the file we’re trying to play on the TV has audio formats that aren’t compatible.
Often, when you connect your TV to a sound system or another audio device or try to play content via USB, the audio format it receives may not be compatible.
It is important to note that unsupported audio formats can cause problems such as no sound, distorted sound, or even incompatibility errors on the TV display.
Recently, when I was trying to play some old videos from my USB drive, I encountered a problem when I tried to connect it to my TV but the video wouldn’t play with sound because it had an unsupported audio format issue as stated by the TV’s error message.
Fortunately, this issue is relatively easy to resolve by changing either your TV settings, converting the video file to a supported format, or adjusting the connection between the sound system and television.
We’ll start by checking if your TV supports the audio format you’re trying to play. If it doesn’t, we will discuss how to fix the issue later in this article, but first, let’s talk more about TVs and what audio formats they support.
What audio formats are supported by your TV?
We often skip certain things when buying a new TV, such as the Audio and Video formats it supports, since we usually don’t need to know such things, as we only stream content through them, either via applications, cable boxes, or through connected streaming devices such as Roku, Firestick, or Apple TV.
Different TVs may support different types of audio such as Dolby Digital, DTS-HD Master Audio, PCM, or LPCM. It’s also important to know that some higher-end models do have multiple ports which can support different types of playback methods like optical cables, HDMI, or RCA connections for example.
Most of the Smart TVs, especially which came after 2013 (when the actual Smart TV era started) do support almost all commonly formatted media.
These are all the most commonly supported audio and video files on smart TVs:
Common Audio Formats Supported By TVs:

Software Based Converter

Tips For Troubleshooting And Fixing Unsupported Audio On Smart TVs
- Check the audio output settings: First, check your TV’s audio output settings and make sure that you have selected the correct format for the device connected to your TV. If you are using a home theatre system, make sure the sound is coming out of it instead of directly from the TV.
- Update firmware/software: Next, make sure that your TV has all its latest software updates and firmware installed. This can help ensure compatibility with any new devices or formats you may be trying to use. Often the new updates from TV manufacturers enhance the capability to process the new audio format.
- Check connection cables: If the audio format is not supported by your TV, then it could be a result of incorrect connection cables or poor connections between your playback device and the TV. Make sure all cables are securely connected and that there aren’t any visible signs of damage. Additionally, if you’re using an HDMI cable for audio output, make sure it is compatible with both your playback device and television set.
