Lip sync on Q90R with 5.1 input

[d00p]

I -- and judging from posts in various fora on the web, a lot of other customers -- experience lip sync issues with 5.1 surround sound input on the Q90R (firmware v1066).

Specifically, I experience this on TV channels that are broadcast with 5.1 sound, but not on TV channels that are broadcast with only stereo sound.

This means that I can watch a show on one TV channel with the (stereo) sound and picture in perfect sync, and then simply change channel to another TV channel to experience a mismatch between the (surround) sound and picture. Switching back to the first TV channel, the (stereo) sound and picture is again in perfect sync. So lame 😕

The lip sync issues are present using the Q90R built-in speakers as well as with a Sonos Amp -- however, again, only with 5.1 TV channels, which also means that I cannot use the options for adding a general delay on the sound/picture as that, while perhaps fixing the 5.1 TV channels, will simply shift the issue to the stereo TV channels.

@Samsung: Needless to say, having such issues on a flagship model is really bad.. What are the plans for fixing this (expectedly, through a firmware update to get the TV to process 5.1 sound input properly)?

Awesome. I plugged in my new Q90T and was dismayed to see a delay in the sound. Following your menu settings I discovered that there are “basic” “slow 1” and “slow 2” settings for the HDMI socket. This appears to have slowed the video signal coming into the TV from the BT TV box so that the sound matches the video. Thanks for posting

Hi, According to Samsung support page https://www.samsung.com/us/support/troubleshooting/TSG01202002/  this HDMI setting has to do with the time out before the TV concludes that there is not input signal. Are you sure that it corrected the video/audio delay problem?

Yesterday I connected the sky to the soundbar as the lip sync has been driving me crazy. After a power cycle of the sky box at the start everything seems to be working as it should.  Turn the tv off the soundbar turns off. Turn the tv on and the sound bar comes on. The soundbar hasn't lost the source hdmi1 like before.  I had loads of trouble with this set up before so not sure what's changed.no firmware change for the soundbar. Tv is running 1359. Only have the tv and sky connected by HDMI. So maybe not using both HDMI ports might have helped.

Hi @shaunevo 

I have a very similar set up with my Sky Q box connected to HDMI 1 and a 4K Blu-Ray Player to HDMI 2 on the Soundbar.  The vast majority of the time I only use the SKY Q box, or internal TV Apps for viewing and my system has been stable for a long time now.  I can get HDMI related problems after using the Blu-Ray player, which may necessitate a power cycle of TV and Soundbar.

Occasionally I can experience the Soundbar not turning on with the TV, but I have set up a script in Smart Things App to ensure Soundbar is On if the TV is On which works OK, albeit it's not as instantaneous as via HDMI control.

Another infrequent problem I have experienced is the SKY Q box not outputting a signal on HDMI but I'm satisfied that is an issue with the SKY Q box and it has been a reported problem on the SKY forum.  It requires a reset or power cycle of SKY box to correct.

When it's all working it's great!

My Q90 soundbar has been updated1010.5. 
think that's why I can connect my sky box to the soundbar without issues.

are you no longer having any lip sync issues after the eArc update?

[shaunevo]

I know have the sky into the soundbar first.  The tv turns the soundbar on and off and so far I don't need to keep power cycling everything.

I don't see a possibility for removal of the excessive audio delay, introduced by the Q90R TV, until also the TV has been updated to eARC.

Introduced before the Q90r tv, I have the Q9F75 2018 model and have exactly the same issues with the OCB and Q90r soundbar. I'm hoping any eARC update for TV's will apply to mine, not overly hopeful mind...

Yes, I know. What I meant was "the delay caused by the TV" has no chance to be corrected by updating only the connected soundbar to eARC.

How do you find out if you have the update
