Your TV may be sending an audio format your Avantree transmitter cannot decode. Select your TV brand below to find the audio setting and change it to PCM.
1. Select Your TV Brand
Tap your TV brand to see where to find PCM.
2. Find PCM on Your Samsung TV
Your TV's menu may differ depending on its model and software version.
Can't Find the Same Menu?
Look under Sound, Audio, or Audio Output for one of these settings:
The setting may currently show Auto, Dolby Digital, Bitstream, or Pass Through. Open it and look for PCM or PCM-Stereo.
If the setting is greyed out, check whether the TV requires Optical / Digital Audio Out or HDMI ARC to be selected first. HDMI ARC applies only to compatible Avantree transmitters.
3. Still Can't Find PCM?
Your TV's menu may look different. You can check your TV's user manual online for the exact audio settings.
- Find your TV model number, usually on a label at the back of the TV or under Settings → About.
- Enter your model number below and select Find My TV Manual.
- Open the manufacturer's manual and search for PCM, Digital Audio Out, or Audio Format.
Tip: If the manual opens as a PDF, press Ctrl + F on Windows or Command + F on Mac, then type PCM. On a phone, use the PDF viewer's Search option.
For the most reliable instructions, choose the manual from your TV manufacturer's official support website.
Using a Cable Box or Streaming Device?
Your cable box, streaming device, or game console may also need its audio format changed to PCM / Stereo.
View Cable Box Audio Settings →Note: PCM settings are generally needed for digital connections such as Optical or HDMI ARC when your Avantree model requires PCM. They are usually not necessary for 3.5mm AUX.
