I can not achieve 5.1 audio when viewing HD broadcast TV. Can any one advise how I can achieve this please?
My set up is as follows:
Sonos Beam paired with two Sonos One SL speakers.
The Beam is connected to a Samsung TV with The ARC HDMI input. The TV Model is:
I use a Humax Freeview Player to receive the HD content:
The Humax is connected both via a HDMI cable and SPDIF to the Samsung TV.
The setting on the HUmax are set to Doby Digital for both HDMI and Optical outputs.
I have used The Simspons broadcast on Channel 4 HD which shows in the guide that it is broadcast in 5.1 to test the surround system. Looking at the About System page of the Sonos app I see that the audio input is Stereo.
In the sound settings for the Samsung menu I have selected External speakers. The menu options in Additional Settings for Sound shows SPDIF Out set to PCM. The Dolby Digital option is greyed out and not selectable.
When I switch source on the Samsung to USB and play a media file (eg Movie) from a hard drive the surround sound works. I confirmed this on the Sonos App which shows the audio input for the Beam as 5.1.
It appears that my TV can out 5.1 to the Beam from the USB Media but not from the Humax HDMI input. I added the SPDIF connection between Humax and Samsung as a final attempt to get the 5.1 for broadcast TV when available.
Any suggestion how best to proceed would be very greatfully recieved.
