Hello! I apologize in advance for my English, I am from Belarus (I used Google translator a little
My setup is the LG B8, HW-Q90R, PS4 Pro, PC.
I have several issues that I think are related to the handshake of the HW-Q90R, maybe you can advise me something. We have a small community of owners of the HW-Q90R, so there is not much information, but not only me have such problems.
1. The first issue relates to connecting the PS4 Pro and PC through the soundbar (pass-through) to TV. When connecting the PS4 Pro and PC directly to the TV with the same HDMI cables, there is no any issues.
For some reason, pass-through on the HDMI 1 soundbar does not work when the "Ultra HD Deep color" setting is enabled on the TV (this is LG's HDR support) - I see a black screen or flickering. But everything works fine with the HDMI 2 soundbar. When testing the same cable was used for both ports, of course. I checked several HDMI cables and all did not work with the HDMI 1 soundbar, but they worked with HDMI 2.
Moreover, without HDR support ("Ultra HD Deep color" is disabled on TV) everything is OK, HDMI 1 perfectly forwards the picture. This is for PC output.
When I connect the PS4 via HDMI 1 soundbar (pass-through), when I try to turn on the HDR mode, sometimes (not every time) something goes wrong and the TV cannot receive the signal, I see a strobe and white noise on the screen.
This is pure random, no dependency, succeed or not. If the TV switches to any other source and then immediately back to HDMI ARC where the soundbar - everything is ok, the handshake is restored.
2. The second issue is associated with interruption of sound on the film tracks in AC3 format if a bitstream is used to the soundbar. Sometimes (not every time), the sound begins to stop, sound jerky. And this is not the whole film, but only certain places, I remember them and I can always repeat this issue to demonstrate.
If I turn off the movie and turn it on again, the issue will go away.
If I use PCM instead of bitstream, then there is no issue.
The problem is reproduced both when listening to the internal player and when using an external source, it is always there - when using a bitstream .
I can’t imagine how it is possible to check in the service center from my words, if I go there.
Thanks in advance for the answers.
