[Solved] Audio Out of Sync on TCL Roku TV After 14.6 Update?

Hey everyone!

Thanks for reporting!

Status update 6/9: We're currently investigating the audio issue impacting customers with TCL Roku TV, which was out of sync after an update.

To help us know more about it and proceed with the investigation, can you share some info?

• Do you have any other audio devices/peripherals connected to your TV?
• If you have, does the problem persist if you use the built-in TV speakers?

Let us know what you find!

Thanks again,

I am chatting with Support now about this issue. I have restarted my TV several times. And I refuse to do a factory reset because I will lose everything I have set up. They are trying to get me to a specialist . . . the chat session is going on an hour . . . still going . . . guess I should have called . . .

I made a ticket with support last night, they said they would respond via email. Today I tried just removing and reinstalling one app to see if that would resolve the issue with that app, and it worked. So I've spent the entire morning uninstalling and reinstalling every single f ing app on my TV. So fun! The only app that doesn't seem to be resolved is the Roku app. And feeds from my antenna still are not in sync. FWIW.

Well, after updating all those apps, they are now all back to not syncing again. I don't get . . . what a waste of time . . . perhaps a system update will resolve the issue.

Hey there, BreenX 

Thanks for reaching out about this!

Looks like you're having some trouble with the audio on all your apps, and we're on it! We see you've already reached out to our support team, so no worries— we'll pass your info along to them for a look.

We'll keep you posted!

Thank you very much. I don't know if this information is helpful, the Netflix app appears to be unaffected by this update. Netflix works fine, no issues. The other observation I have is any "live" streaming content on other apps are fine. It's only when viewing "on demand" content that the audio and video are out of sync. Again, Netflix is the only app I have that seems unaffected. FWIW.

HiBreenX​,

Our team is currently taking a closer look at the issue you’re experiencing. To help us troubleshoot more effectively, could you let us know if you have any audio peripherals connected, like external speakers, a soundbar, or headphones?

I’ve also sent you a direct message so I can assist you further. Looking forward to your response!

Thank you,

Model: TCL 66R655
Over the last 2 years, there had been several occasions were audio / video were very noticeably out-of-sync, and in my case always with sound preceding video. Not speaking to external sources like PS4 or PS5 playing a BluRay disc, which have their own challenges... this post is about streaming apps. These issues seemed to have been reigned in recently, until now.

Now, it looks as if the current problem started with Roku OS update 14.6.4 (9905). Audio precedes video by about 250-300ms, and this can be verified with AV sync test videos that are available on Youtube. So I did use the iOS Roku app once more to fix (calibrate) the A/V sync, which only seems to take effect after the TV has been restarted again. 

After restart, the sync is fine for a while. But then at some point (and I cannot find an obvious trigger), audio again becomes out-of-sync (for all apps). Have to restart the TV again to fix this. I wonder if this is the audio/video calibration that stops working somehow. (Might verify my suspicion later on, since the calibration can be reset in the Roku app.)

Notably, some apps still have slightly early audio in general (such as Shudder), which is barely noticeable when things are good, but extra worse when things have switched back to bad. I wouldn't write this post if all this had been old news, but the on-and-off intermittency of the problem ,fixable by restarting, seems new since the last software update.

My audio goes to an AV receiver via optical cable and is configured as such, with Dolby 5.1 as default.

Any advice or other folks experiencing the same?

I have the same issue and it started happening at or about the same time frame.  The video is behind the audio.  I tried a hard reset on the TV and it didn't help.  I called TCL and did what they told me to do, it helped a little for about 5 minutes and then went back the way it was, not matching up.  This is happening with all of my streaming apps, MLB, Youtube, Netflix etc.  Is this a Roku system issue?
