Recently I bought a new SAMSUNG 5-Series LED TV. It’s great in sense that it has a SPDIF/Out (compared to my old Panasonic HDTV) , it’s mcuh more lighter and it’s a SmartTV.
As you do know that I use HTPC to play back videos from the internet and all and currently the configuration is setup as Video to HDMI and Audio via SPDIF/out to my Amplifier. The reason for this setup is being that my previous HDTV did not have any Digital Out. But this current Television does support it.
So I’ve decided to connect the Toslink cable from my HTPC to my TV instead so that my HDTV can make use of the amplifier , thus making it easier for any devices to output 5.1 surroundsound. Unforutantely , this setup did not work very well with my PC.
The reason being is that moment I plugged in my HDMI Cable , Windows did detect it’s a HDTV and only offered 2.1 Audio. It did not offer Dolby Digital/DTS pass-through which means that if I play back a Dolby Digital 5.1 , it would not output correctly to my Surround. Of course other systems like xbox , STB are able to do this correctly moment you set the correct output
However in Windows (and with NVIDIA) it was not possible to bypass this. It would read EDID information from the TV. Thankfully there is a method which allows you to bypass that. This person has written a guide on how to do that , step-by-step instructions on how to do it
It works great with NVIDIA Cards a well , it’s just that after you have done the configuration you may have to re-install NVIDIA Drivers to correctly detect your Audio output 🙂
Let me know if it works for you
