Hello everyone, i just bought a 5.1 surround sound system, and connected it to my tv with an Optical Cable but the TV outputs only stereo sound. What can i do? I already set the TV to output to "external speakers" and set the digital audio to "PCM" but still i can't get 5.1 surround.
(FYI the surround system is a Sony HT-S20R
Solved! Go to Solution.

Ok, Just FYI, after many days of research i found out that the problem is that Samsung doesn't pass through 5.1 audio from HDMI to Toslink. Pretty bad functionality but ok

Hi, change to Bitstream on the TV so that the audio data can be sent compressed to the sound system.
This way, audio decoding is handled by the 5.1 receiver.
If the system has HDMI, you can use PCM thru HDMI. Optical cable has low bandwidth and can't handle 5.1+
Please check this link for more detailed information.
Have a great day!

Thanks for the update.
Please try the following:
Dolby and Bitstream may not be available in case of using a set-top box broadcasting audio only in PCM.
For example, if using an XBOX console, you need to go to settings and select the same options so they may be paired by the TV/receiver.
I hope this clarifies.
Example on XBOX:
Format: Dolby D

I have a PS5 and a FireStick, but :
If i put the firestick in dolby or DTS, the speakers mute themselves
If i put the PS5 in dolby or dts the audio is still stereo.
In both cases the Dolby or DTS options on my tv are Grayed out

All devices must be compatible or else the settings will be grayed out.
To be able to configure the TV, first set the player/set-top box/console to the appropriate settings then the options will be available on the TV.
To enable Dolby or DTS on the TV, you must use bitstream. That is a requirement for optical cable. You can use PCM over HDMI.
