I've had sound issues with this TV since I bought it. It has been very intermittent and frustrating. At first, I had a normal set up with just the TV and my router connected to a cable modem. Needless to say, the sound would just intermittently stop playing through the TV speakers. Sometimes I would have to turn off the TV but other times just switching the input would fix the no sound issue. This also happened when I was streaming. Sometimes the sound wouldn't come back on at all and I would have to turn off the TV and wait quite a while before it would start working again. Then I decided to buy an external speaker system and connect it via the optical data link. Unfortunately, this did not correct the problem. It is still totally cutting off my sound at various times. I noticed a big difference when I first turn it on. This is mostly when it cuts out. But it actually does go off while I'm watching various things. This also happens when I'm on HDMI 2 and playing Xbox. So I'm having the same issue while it is on Input tv, HDMI 1 (added a fire stick 4K) and HDMI 2. I also checked to see if I needed to do an update. It is at the latest release. Is there anyone that can help me with this TV. Hopefully from Samsung. Thank you.
Does the same happen with internal apps? Have you tried to factory reset the unit? What is the current software?
A newer version is uploaded on the Samsung website that specifically addresses the audio mute issue!
There are instructions on how to update your TV firmware using USB stick.
I've had the tv for two years now and no firmware updates they've offered (yes I used the USB method) have worked. I'm so frustrated I'm finally throwing in the towel and buying an LG or Sony tv tomorrow. It completely ruins my gaming experiences. I even ended up buying two Xbox One X's thinking it was the console.
I have the issue with a NU7199 and nothing connected. Just exit Netflix after some watching using the goback and then Exit menu option from netflix main screen and sound is off. Always. I am on 1300.4 firmware.
I have a new The Frame (2020) 55" TV connected to a soundbar via HDMI ARC. I am experiencing significant audio cut-outs and popping sounds (1 second every 5–10 seconds), no matter the input.
I have tried other HDMI cables, cycling the power on the soundbar, disconnecting and reconnecting the soundbar, etc.
The only thing that seems to temporarily resolve the issue is a full power cycle on the TV, e.g. unplugging it from the wall for 10 seconds, then plugging it back in. If I do this, audio over HDMI ARC is fine for the viewing session that immediately follows.
If I let the TV go to "sleep" or frame mode for any period of time, the audio issues resurface.
Curious if anyone else is experiencing this and if they have found a more permanent solution?
