On my PS3 via HDMI cable with my Onkyo TX-SR875 AV Amp I get true HD 5.1/7.1
But on my PS4, outputs only a 2.1 signal via HDMl; I have swapped
cables and inputs between the PS3 & PS4 and it makes no difference.
On the PS3 there are options to output with different audio settings via
HDMI but on the PS4 there are no options?
I only way I can get surround sound is via the optical output which does
have options to select the audio output, but this is only standard 5.1 (and blu-ray films sounds
rubbish compared with the PS3).
Anyone else having similar problems?
