Q95T audio passthrough is broken

[Suriya]

Can anyone help me pls?

HDMI '1- Ps4 Pro connected

HDMI '3 eARC - Samsung q70r soundbar connected (latest firmware with eARC support)

In q90t there is an option to passthrough audio via eARC to the soundbar without any processing applie by the TVs software (unprocessed audio LPCM) to the soundbar to process it But it is not working.

When i see in game audio option it is showing Television 2.0 channel by connecting Playstation directly to TV on HDMI 1 then TV to soundbar via eARC HDMI 3 Port and select PASSTHROUGH under digital audio output format in TVs expert sound settings.

When i connect Playstation directly to q70r soundbar HDMI IN (to pass video via soundbar) then soundbar to TV via HDMI OUT to TV (any HDMI) under game in audio menu it is showing Hometheatre 7.1ch.

Playstation main audio output is set to Linear PCM (unprocessed audio)
In game menu is properly showing 7.1ch when ps4 connected to soundbar then TV.

But if ps4 to TV it should passthrough without any processing to the soundbar to detect 7.1ch linear PCM when i select passthrough but it doesn't.

Using premium HDMI promate cables and tried with stock cables given by manufacturers no use.

eARC set to auto
Soundbar is showing eARC

Same issue here with Samsung HW-Q950T soundbar.

The only workaround I found is to set audio output to bitstream (DTS) on the PS4 and activate passthrough on TV. Thereby I noticed an acceptable delay between image and sound.

However it's a real shame that we cannot benefit 7.1 LPCM passthrough on such high-end device.

Samsung please do something !!!!

I am having the same issue on Q80T.

No direct response from Samsung yet.

Sorry for necroposting, is there any audio or video delay when plugging the PS4 - PS5 to soundbar and then the soundbar to TV?

It's happening in all the 2019 to 2021 models. Samsung didn't acknowledge this.
