I have a ROKU branded TV. Recently noticed that I lost the surround sound. I am using a Samsung soundbar with rear speakers and sub-woofer.  I also noticed that the tv audio is locked in standard mode. I am connected to the tv via Earc. I have seen others with this issue but never a clean fix for it. In the audio output in settings, it is set to my soundbar.  I have seen others with this problem, but never a clear solution. Responses say it may be a channel causing this. How do I check settings per channel, when the issue is across all channels. This looks like a common problem. Is there a common solution. I want to enjoy surround sound again.

Hey @kjdunn29680,

Thanks for reporting this issue here! 

If the sound mode on your Roku TV appears to be locked, it may be because the audio settings are configured to a specific mode. This could be due to a setting for a particular channel or a pre-configured audio output on your TV. Additionally, it’s a good idea to check if your Roku is set to automatically detect the best audio format, as this could be causing the sound mode to stay fixed on a specific setting.
I hope this helps!

Thanks,

I'm not using a Roku box. This is a Roku branded TV set.  I have tried every suggestion even doing a factory reset. Still not resolved. Telling me what might be causing it, doesn't help me fix it. Like give me the steps to see if it's a channel causing this.

All settings are chosen for the soundbar I am using. Nothing is set to automatic.

Hey @kjdunn29680,

Thank you for keeping us updated. Could you please check this with your Samsung Soundbar setup?

• Is DTS or Dolby Digital enabled?
• Do rear speakers and sub work when testing directly through the soundbar’s test mode or native Samsung sound modes?
• Make sure it’s not on “PCM only”, which downmixes to stereo.

In the meantime, you can try these steps:

1. Unplug the soundbar and TV for 10 seconds, then plug them back in
2. Try a different HDMI cable, especially a certified High-Speed HDMI with Ethernet.
3. Ensure CEC (1-touch play) is turned on on both devices to help HDMI sync up correctly.

Let us know how it goes
