Beam - TCL (roku) TV sync issues

25 replies
13156 views

Hello, I have a beam connected to the following TV via HDMI (ARC):

TCL - 49" Class - LED - 4 Series - 2160p - Smart - 4K UHD TV with HDR Roku TV

I can NOT get the visuals to synch with the audio (ie lip synch issues).

I have (obviously) tried adjusting the delay under the settings for the Beam on the app, but that only makes it worse.

It renders watching tv/movies unwatchable.

Anyone else experiencing this/any ideas?

Thank you.

George

I'm having the exact same with a TCL 49S405 49-Inch 4K Ultra TV and Sonos Beam connected via ARC HDMI. Have tried changing all the settings in audio for the TV: stereo, Dolby, Dolby + etc etc. Absolutely frustrating that I just purchased both of these products new and the ARC cross-talk is not working. Have tried router reset, unplugging, changing settings. All to no avail - the sound is already playing after the relevant video. When is this going to get fixed?

Rpc12,

The thing is that the Beam TV audio-out is working just fine with so many other brands of TV already.

Quite obviously it's the actual TV that processes the audio and sends it out through the HDMI-ARC port. So it's really whether the TV is doing that in a timely manner for the Beam to then play the audio it receives.

It's perhaps notable that the Beam is already working well with plenty of other TV brands, so this might perhaps be an issue with some TCL TV models and that a firmware/software update maybe required.

I don't think anyone can yet jump to any conclusions, as these things sound like some further investigation maybe required here by both TCL and Sonos.

I doubt anyone can yet say what's causing the lip-sync delay, never mind answering your question of "when is this going to get fixed?' ...simply because these matters are only just now being reported and investigated here.

Presumably some enquiries need to be made with TCL too as it seems other people are reporting similar issues with their TV's and other peripherals... as shown in these few 'example' links below:

This one mentions problems with a HDMI control board in the TV...

And there appears to be quite a few hits when you search google for 'TCL Roku TV and HDMI-ARC problem'.

Thanks all - MUCH appreciated. I will try all of these things. In the meantime, i did swap out the hdmi chord that came bundled with the Beam for a high-speed HDMI (I always thought that (high-speed HDMI) was just a marketing ploy). It has improved the situation dramatically. Not completely, but it’s at least watchable now. Again, thank you all for the amazing input. What a great community and great company. George

@Ken - I’d be very interested with what response you get from TCL. If you hear anything would you mind passing it along here - or private messaging me? Thank you.

Actually, upon re-reading, i guess I should have directed my request for an update on what TCL says to @rc12 not to Ken. My apologies. @rc12 - if you happen to see this, and get a response/learn anything from TCL - please dm me here. Thanks. George

I am having the same issue with my newly purchased TCL Series 6 55" Roku TV. The Beam is connected via the Arc HDMI. There is absolutely no issue with sound from any of the app based sources (Netflix, HBO GO etc). However, when I switch to Cable TV there is a considerable video/audio sync issue. The cable is connected via a DVR box connected to the TV using one of the other HDMI inputs. It is so bad I am debating what to do with my Beam and/or TCL TV.

If anyone has any thoughts on how to fix this I would appreciate it.

I've got the same model, so same problem. What did you end up doing?

Can anyone turn on their TCL with Alexa? I can turn it off but not on.

I have the issue with: TCL 49S405 49 inch TV

I see the issue on both the internal Roku software as well as when i'ms streaming from a fire-stick that i've put in to the tv. There was a suggestion to disable "automatic audio" settings so I've tried both limiting the audio to Stero and Dolby D - neither seems to have fixed the issue.

I'm lucky enough that I purchased the TV recently so its still under the return window.

I'm pretty sure its a TCL/Roku issue not a sonos issue - but maybe if you guys take a look you'll find something useful.
