Hisense U8H TV with lip sync issues when using Spectrum
Have a new Hisense 65U8H and I am having issues with the sound not matching peoples lips with Spectrum cable. I have an Arris/Motorala cable/DVR box (not streaming Spectrum). It is occurring on both live TV and on recordings on the DVR. Sometimes I can temporarily fix it by turning the cable box off/on. Sometimes I can press the pause button on the remote with either live TV or recordings and it will temporarily fix the issue. This only appears to occur with my Spectrum cable that is on its own HDMI. I tried using various apps like YouTube, Netflix, and others on the TV without any issues. I called Hisense support when this started and they said since it is only happening with Spectrum it is not a problem with the TV. I have spent several hours on the phone with Spectrum support. They say they tried everything they could. They sent out a tech to my house yesterday. He spent about two hours and could not fix the issue. He tried changing setting on the TV at first without success. He confirmed that I am getting a good signal with his meter. He replaced the HDMI cable. He did everything he could think of without success. He wanted to replace the cable/DVR box but I had a couple of recording saved that I wanted to watch so I went to Spectrum locally this morning and got a new box. It also did not fix it. Spent 45 minutes with a Spectrum support person this afternoon that tried a whole bunch of thing without success. They are sending another tech out tomorrow afternoon but I am not convinced that this is going to get fixed. I plugged the TV into an outlet on another circuit as a long shot. No success.
Any ideas? Thanks---

Thanks Satch - Noticed shortly after I installed the TV last week. It appears to be on all channels but is intermittent. I can be watching a channel where the voice is off then switch to another channel and the voice might be fine. Its very strange. Sometimes the voice is barely off sometimes its like a second or two off. Cable box has been unplugged, new signals sent, etc, multiple times. And a new cable box has been installed.

Spectrum tech that was out yesterday said he has never seen this issue and he has five years with Spectrum.

Satch - thanks for the interesting possibility. Mine is just a standard setup with a splitter that goes to the Spectrum modem for internet and the other to the one TV that I have hooked up. The Spectrum tech that was out the other day said that the meters they use are really dated. He or another tech is going to be here a 1PM EST today. I'll mention your post if he does not have ideas on how to fix this issue.

Satch - Thanks for all of your help and suggestions. The Spectrum tech, that came out today, was a rookie (7 months). She had no clue what to look for. Very disappointing. You would think on a follow up, after the previous experienced tech was here for two hours, that they would send out someone with a little more experience. She checked my signals including the cable going to the cable box from the splitter and said everything is fine. I showed her how to get into one of Spectrums menus by turning the cable box off and pressing the "menu" button on the remote. She said she had never seen this. There are various setting including one under "Lip Sync" called "Lip Sync Delay". You can set lip sync to OFF, AUTO, or MANUAL.. On Manual you can change the "Lip Sync Delay" from 0 msec to 500 msec in 50 msec increments. I had previously played with these settings without success. The tech was pretty useless.
I spent some time on the phone with Hisense support prior to Spectrums arrival. The first rep said I needed to set the TV back to factory setting which might resolve the issue. It didn't. I called back and the next rep sent me a beta firmware update vis email. It also did no help.
I also hooked up my 32" TCL smart TV to the cable box for an hour or so and had no problems with lip syncing.
After I wrote this I tried your idea about removing the splitter and doing a direct connection to the cable box. Satch your a genius this eliminates the problem. I tried a couple of old splitters that I had but the problem is still there. Waiting for Spectrum dispatch to call me back to setup another appointment. Are there certain splitters that might fix this or will they have to run a a separate line which would be a pretty big task?

Hi Satch,
I currently need the splitter for internet. I also wonder if there is some other splitter that would resolve the issue. I really don't want to run a second if I don't have to. Thanks again for looking into this.

Try it with the splitter in place but the cable modem shut down. Then try it with the splitter in place but with the coax to the cable modem disconnected from the splitter & with that -3.5-dB splitter port terminated by just, say, a different coax going to the cable/antenna port on the TV (or even unterminated if you have to.)

Satch & HT_Greenfield -
Thanks to both of you for all of your help. I ran a new coax from the splitter and the cable box and then connected it directly (eliminating the splitter) to eliminate the coax being the problem. I was getting the voice issues when I did this. Yesterday I tested this twice for about 5 minutes each switching channels etc to confirm this fixed this issue. Today I can not get what I thought was a fix to work. I cancelled my appointment with Spectrum for a tech to come out and I will returning this TV to Best Buy. So sorry I wasted your time.

Need to clarify what I said above. I ran a new coax from the splitter and the cable box and then connected it directly to eliminate the coax being the problem. The problem persisted. I then tried to recreate the fix that I thought I had but eliminating the splitter and could not reproduce it. Not sure why it worked yesterday but like I previously said this has been intermittent but I could usually reproduce in a minute or two by changing channels, pausing the TV etc. Yesterday when I did this with the splitter removed it worked fine. However, the test was only for a short time.

one more time --- Need to clarify what I said above -- again. I ran a new coax from the splitter to the cable box (not directly - eliminating the splitter) to eliminate the coax being the problem. I look like a complete idiot.

Thanks for the additional input. Hisense sent me the beta firmware via email yesterday and I installed it. It did not help. One of the reasons I went with Hisense was that it supported ATSC 3.0. I'm hoping to try going Over The Air again next year with a Televes antenna. I tried going OTA in 2016. I had high end antennas from Antennas Direct with a good pre-amp and the antennas around 30 feet. Along with an OTA DVR. However I'm in a poor reception area and got frustrated after a year with poor/spotty reception. Experts on an OTA Facebook group read my "rabbitears" (rabbitears.info web page) report recently and said that a particular Televes antenna should do the trick for me. However, it will be a pretty significant investment without any guarantee of working..

Bought a Samsung 60" Q60B. Has worked perfectly since yesterday morning. No ATSC 3.0 and picture is not as nice as the Hisense but no lip sync issues. Thanks to everyone for their assistance with this issue.

We have been having the same issues of 4 TVs, some older some brand new. Lip sync issues, pixelating, picture stalls. This started happening with Spectrum did a major upgrade a while back. At a loss. We have have reset everything etc and followed thru with checking connections etc. It is not our TVs or connections. It is Spectrum's end.
