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)?
I am sure most that most of you aware, on here, that the Q70/80/90R range of soundbars received an eARC firmware (1010.15) not so long ago, this was also severly delayed from their support roadmap.
In the same anticipation, we should hopefully get something for the QXX series TV (maybe limited to a few in the range) from the 2019 range as this needs to work with the eARC update on the respective soundbar(s).
Whats really ironic is on this forum also there is a thread, where they are discussing LG TV's (C9s etc) working well with the aforementioned soundbards above (after the eARC update) - a right slap in Samsungs face I say!
looks tentative July/August ...this year I hope!
It's quite ridiculous that Samsung has managed to produce a flagship soundbar that works on their competitors TV but not on their own flagship TV. I wonder how the design brief went....'Team, let's design a top notch soundbar that works on all of our competitors TV's but not our own...'
If the Samsung TV update doesn't come out when my Sonos Arc arrives next week I will be selling my Q85 and getting a C9 or B9 which have dropped in price recently, and won't touch a Samsung product again.
It's absolutely ridiculous that Samsung update their soundbars so they work with competitor TV's but won't/can't update their own TV's.
I found how to fix lip sync on the Q90T TV. I'm using a Q70T sound bar. Plugged Blu-Ray player into sound bar. Sound bar into arc port on tv.. Cable box, PS4, Nintendo Switch/classic NES (switcher) in the other three tv HDMI ports. Blu-ray worked fine like this. PCM worked for the others. Then I enabled eArc on the tv. And more importantly I selected audio pass through. The sound from the devices connected to the tv now pass through the tv unaltered and get decoded in sync by the sound bar. All devices have bitstream selected and Dolby turned on now. Not sure if pass through is an option on the Q90R tv, but that's the solution on the Q90T
I have been in fairly regular contact with the UK CEO's Office Escalation team. I corresponded with them on Friday to ask for a timescale for release of the eARC update for Q series TVs. Having checked with their product specialists, the Escalation team were not able to provide any commitment on a timeframe for the update.
Obviously, this is disappointing and frustrating as this update has now been talked about for over 1 year. If and when I hear any further news I will post again.
