Re: HTRT5 Lip-Syncing. Is there a fix?

Not yet.  The Sony guys called me the other day to go over some issues and unfortunately I missed the call.  I've tried calling them back twice, but after 45 minutes of being on hold, I just hung up.  SOOOOOOOO frustrating.

This is very frustrating. After watching TV the lip sync issue is very bad. Switching channels fixes it for around 15 mins and then it creeps back...

Hello 117w33n,

 

I wanted to reach out to you for two reasons:

1) To check how the new configuration has been working out for you.  

Has it continued to have better performance?

 

2) Could you let me know your Set Top Box model and manufacturer?

Based upon your GPS coordinates, it looks like you are either in Poway (with Cox ISP) or Escondido (with Time Warner).  Cox recently switched over to a purely digital Set Top Box service that we have a theory may be contributing to the mismatch between the Audio and Video syncs as the timing gets worse over time.  However we have very few complaints concerning the Audio Sync and have not been able to confirm this theory.

 

Thank you again for all of your help and we hope to resolve this issue permanent

Thank you very much,

Chris

Re: HTRT5 Lip-Syncing. Is there a fix?

Hi Chris.  I am in Escondido, using Cox.  The unit is a Cisco Explorer 1642HDC.  I am optimistic that Chad has found a solution, by feeding the TV from the HTRT5.  So far all channels have been doing well, expect for MTV.  That one has always been the worst, which leads me to believe it may be their broadcast.  Check back with me in a couple days, if you don't mind.

Re: HTRT5 Lip-Syncing. Is there a fix?

Hello Gr4z,

 

Is your system set up like this:

HTRT5 > HDMI > Television > HDMI > Set Top Box

 

If so, you could you switch your system to the following:

Set Top Box > HDMI > HTRT5 > HDMI > Television

 

This configuration should better support any audio sync that may be related to either your Television processing the video signal or any Set Top Box issues that my be causing this condition.

 

Could you also provide your ISP and Set Top Box manufacturer and model?

 

Thank you,

Chris

Hey all,

 

I have been suffering with this issue also. It is frustrating beyond words. I have found the only way to recover sync is to power cycle the soundbar (which takes about 45 seconds). Even that doesn't work all the time, however. It sometimes takes multiple restarts to resolve. Even then the sync might only be correct for 5 or 10 minutes.

 

Its also worth noting that the sync drifts and worsens if you don't address it.  You might notice that it is barely off and then after a few minutes it may be much worse. Because the sync issues drift over time, the idea of adjusting an audio delay setting would not be an effective solution, by the way.

 

My signal path:

 

STB (Verizon Fios VMS1100) > HDMI > Xbox One > HDMI > HT-RT5 > HDMI > Samsung UHD TV

 

I thought this might be resolved by the recent firmware update but was disappointed to find that it was not addressed.

 

I would be grateful if you or someone could recommend an action I can take that doesn't require returning this set and buying another brand/model.

 

Thanks very much,

 

Luke

My set up is already:

Set Top Box > HDMI > HTRT5 > HDMI > Television

 

The lip sync is terrible and ruining my experience of this product. Within around 3-5 mins the lip sync issue is noticeable and 5+ mins it is profound and makes viewing uncomfortable. The only solution is to change channels whereby it syncs again for around 3-5 mins and then starts to go out of sync again. 

 

The STB is a Humax DTR-T1000

TV is a Samsung UE46ES8000

I have 1GB fibre internet with ISP Gigaclear.

 

On my previous AV system (a Denon receiver with 5.1 speakers) I never had any lip sync issues.

Re: HTRT5 Lip-Syncing. Is there a fix?

I have the same problem with the a/v sync drifting over time.  I don't notice it after 15 minutes, but after several hours (5-6) it is extremely noticeable.  I can't say how far out it is in ms, but someone on screen can say 4/5 words before the speech actually comes out of the soundbar.

 

My set up is

Sky HD+ > HDMI1 > HT-RT5 > HDMI (ARC both sides) > Samsung UE55JS8000

 

I have a PS4 on HDMI2 and Panasonic Bluray player on HDMI3.  I think I start to see the drift on the PS4 too (after 2-3 hours).  I don't use the bluray often enough to have noticed it.

 

Switching inputs on the soundbar will temporarily fix it, as will changing the A/V sync timings.  Yesterday I changed it to 100 ms, however I changed it back to 0ms about 30 mins ago which seems to be the correct setting today!

 

I've been putting up with it for a while now.  It was present before and after the latest firmware update from earlier this month.

Re: HTRT5 Lip-Syncing. Is there a fix?

Hello everyone,

 

I've done some extensive testing to replicate this condition.  Unfortunately I have not been able to succeed in duplicating the behavior that you are experiencing.

 

I’ve put together all of the information from this forum to determine the root cause of that is occurring.

 

User Location Provider STB Television Comment Setup
117w33n California Cox Cisco Explorer 1642HDC Samsung 630D LED TV ?? Sync worsens over time STB > HDMI > TV > HDMI ARC > HTRT5  and  STB > HDMI > HTRT5 > HDMI > Television
lukezra New York Verizon Verizon Fios VMS1100 Samsung UHD TV ??? Sync Drifts over time STB (Verizon Fios VMS1100) > HDMI > Xbox One > HDMI > HT-RT5 > HDMI > Samsung UHD TV
Gr4z UK Gigaclear Humax DTR-T1000 Samsung UE46ES8000 Sync changes after 5m Set Top Box > HDMI > HTRT5 > HDMI > Television
brianhearn UK Sky HD+ Unknown Samsung UE55JS8000 Sync Drifts over time Sky HD+ > HDMI1 > HT-RT5 > HDMI (ARC both sides) > Samsung UE55JS8000
            Possibly on PS4 also (??) after 2-3 hours

 

Could I get confirmation from 117w33n and lukezra for the full model name for the Samsung Televisions?

Could I also confirm if this condition happens mostly on Set Top Box HD channel programming?

 

Since there is a common condition of a Samsung television, I checked online for any complaints and found numerous sources mentioning that Samsung televisions have an Audio Sync issue.

If any of you have a non-Samsung Television in house, could you confirm if you have the same problem on that television with the same setup?

 

Thank you very much,

Chris
