I recently purchased a ROKU 55R4A5R 4k LED TV. I am having issues with the sound. It is connected to a VIZIO SB3830-DO via the HDMI ARC connection. During some programs when a commercial comes on the sound drops to barely audible, then returns to normal level for some commercials, or when the show comes back on. During other programs, the sound will drop for 2-4 seconds then return to normal. Now here is the kicker, this TV replaced a Hisense ROKU equipped TV via the same configuration (HDMI ARC) and never had this issue during a two year life span. It started the first day we turned the new TV on, so it appears that the TV is the culprit.

I have done a lot of trouble shooting like, checking the settings for both devices, turning everything off for a while, changing to a new HDMI cable that said it was for ARC, and looking for info online. I'm stuck as to why this issue is randomly happening, so decided to turn to here.

Wondering if anyone else had this problem and how they resolved it. I could return the set to Best Buy, but know the first thing they are going to do is say it's the soundbar. Any ideas are welcome.

Hello! @TonyMan13,

Thank you for posting in the Roku Community!

We appreciate your notification regarding the issue with your Roku TV's dropped sound during movie viewing. We're pleased to assist.

Sorry, I missed some info. The sound drops in volume to where it is barely heard  I've noticed it mainly on the recorded Jimmy Kimmel shows on HULU, during football game on Youtube TV, and on a show on MAX. My wife has noticed in on various shows on Youtube TV, but couldn't come up with a specific on. I know there are other examples, but these are the ones that come to mind immediately. And, it's not just these show, it can come up randomly.

Got a couple of instances.

We’ve had more issues, but could not collect the info as before.

While watching SNL, recorded on Peacock, one of the sketches dropped down in sound. We switched over to the recorded version on YouTube TV. On there, many of the commercials dropped in volume. Next, the Sunday night football game came on, on NBC. Many commercials dropped in volume there.

@TonyMan13,

Thank you for the updates.

Please try adjusting the sound by pressing * and going to sound settings during playback. If so, we’d like to see how those settings are set. This could be an audio issue with a specific commercial; if you experience it during any commercial playback, can we get a video recording?

For more detailed instructions, please check it here:  How to change sound settings on your Roku audio device|Learn about sound modes

Please keep us updated.

Best regards,

It’s not just during commercials, it happens during shows also. It’s very random. Another test I just tried was unplugging the soundbar. I went back to a show and the sound did not drop where it did before. This leads me to believe it is something in the TVs HDMI-ARC circuitry since the soundbar worked fine in the Hisense Roku equipped TV I prior to this one.

I don’t get many options for audio since I’m connected to the soundbar. Tomorrow I can see if I still have an optical cable and test the volume drops with that.
