PS4 connected to an HDMI switch


Novice Member
Hi all,
I bought an HDMI switch with power supply, and connected A TV Cable box and a PS4 to it.
There is an HDMI cable connected from the switcher to the TV to get a picture, and Optical spdif cable connected to my receiver.

When i choose the TV Cable box on the HDMI switcher i get a picture in the TV, and a dolby digital sound in my receiver.
When i choose the PS4, i get a pcm sound on my receiver and not dolby digital.

I chose HDMI OUT in the PS4 sound settings, which means that the Dolby digital sound should output from the HDMI connection.

Does somebody knows why i get PCM and not Dolby Digital when choosing the PS4 on the switcher?

Thanks in advance
