Tried it on PS4 pro. Did not recognize multichannel LPCM

Hi,

I Used H10 to connect PS4 pro to my Samsung UHD HDR TV and my AV receiver that supports lossless audio (both Dolby TrueHD & DTS HD MA)

The device cannot deliver surround sound to the AVR when LPCM is chosen in PS4 pro menu, only stereo sound just like the toslink!

I tried every possible connection amd different HDMI cables but to no avail
Selecting Bitstream is no choice as i would do that without the need of this device

Unfortunately I cannot return it back as I reside in UAE and my friend brought it from the UK

Please help.

Thanks!

I didn't find the right solution from the Internet.
