We purchased a 55" Hisense A6 Series 4K Ultra HD Vidaa TV (55A6GV). We immediately noticed the same issue so many have reported to ROKU and the community. The sound from the TV audio outputs do not sync with the TV speakers. We did research and find a great many folks reporting about a 100ms - 200ms delay in any attached sound device (sound bar, speakers, head set, etc.) Theres seems to be no way to correct this issue, and thus all we can only use in the tv speakers. This seems to be an issue with ROKU. We called the dealer, and were told that the sound sync issue is the most frequent complaint they hear about ROKU TVs. They gave us 30 days to return.  The on board speakers, as has been reported, appear to be the only audio in sync. The headset output, the ARC HDMI, the optical audio output, all are not in sync with the built in speakers, and thus there is a sync issue, and an echo. There does not appear to be a way to bring all audio outputs into sync. This also appears to be well reported, and a very common issue with ROKU tvs. Before we take up the return offer from the dealer, we are wondering if ROKU is doing anything to correct this issue? Why is this a ROKU issue in the first place?  Thank you.

Hi @PB03

Thanks for reaching out here in the Community!

For clarification, is the TV you have a Roku TV? What external audio devices you are connecting to your TV? If you disconnect your audio products and just use the TV speakers, are you still experiencing the issue?

Please let us know. We'd like to know more about how we can help.

All the best,
Kariza

Yes it is a ROKU TV. It is a model 55U6GR. Hisense ULED 4K. If you just use the internal speakers alone, there is no issue. The echo or delay (out of sync), occurs when any other external audio device is attached. Be it a headset, or external speakers, or using the ARC HDMI, or using the optical audio, or any soundbar. I have a sony with a sound bar - no issues. I have a samsung with a sound bar - no issues. We have used headsets on these two, with no issues. But the sound from this new Hisense ROKU TV audio outputs do not sync with the TV speakers. We did research and find a great many folks reporting about a 100ms - 200ms delay in any attached sound device (sound bar, speakers, head set, etc.) We called the dealer, and were told that the sound sync issue is the most frequent complaint they hear about ROKU TVs. And specifically the Hisense ROKU TV. The on board speakers, as has been reported, appear to be the only audio that is actually in sync. The headset output, the ARC HDMI, the optical audio output, external speakers, all are not in sync with the built in speakers, and thus there is a sync issue, and an echo. There does not appear to be a way to bring all audio outputs into sync. This also appears to be well reported. Before we take up the return offer from the dealer, we are wondering if ROKU is doing anything to correct this issue? Why is this a ROKU issue in the first place?  Thank you.

It is a Hisense 55" model 55U6GR. SN is 55G22158OUH0064

Various audio outputs - from Sony sound bar, to earphones, to bluetooth audio transmitter, to plug in speakers. It does not matter what audio device used (other than on board speakers). Clearly documented in various ROKU Community Forums.

See attached.

according to the various post in Roku Community Forums. All audio outputs, except the built in speakers are out of sync. And all audio outputs are out of sync with the on board speakers. seems there is a software issue and obvious sync issues when it comes to speakers built in and sync with all other audio outputs.

This occurs using Spectrum TV Cable box, or using any of the many Roku TV apps. Or even a DVD player. all audio outputs are out of sync with the on board speakers.   See attached

Thanks for the post.

Can you please provide more details regarding the external audio devices you are connecting since you stated that the TV's built in speakers are not experiencing an audio sync issue? What specific devices are you connecting to the Roku TV? Can you provide the brand and models of each of these devices so we can better investigate the issue?

With more details, we will be able to assist you further.

Thanks,
Danny

As is also documented in the various Roku Community Forums, any attached sound bar, and attached speakers, any attached headset, any attached optical out device, is out of sync and is especially noticeable as being out of sync with the built in speakers.
