If your using ARC on Samsung then the settings can be a bit confusing
Settings->Sound->Expert Settings
* HDMI Input Audio Format = enable or disable bistreaming, the last Samsung I owned badly labelled these as PCM (disable) and bitstream (enable), Samsung may or may not have changed them.
* Digital Audio Output Format = with bitstream enabled you select the audio format, ideally it should be Auto if Samsung provide it (they didn't on my last unit) so you have to manually select DD, DD or DTS 5.1, also PCM is listed here too which is just stereo. Set it to DD or DTS not DD .
On PS4 audio settings
* PCM = Automatic configuration based on HDMI connection, 2.0, 5.1, 7.1
* Dolby 5.1
* DTS 5.1
ARC is limited to PCM 2.0, Dolby 5.1, DTS 5.1, you can't get the higher quality PCM 5.1/7.1 audio over ARC. |
