  1. Optical is a standart with bandwith limitations. 5.1 is possible only via compressed signal and is up to the receiver if can decode the signal or not . Based on your description, the reason why your audio receiver is only playing stereo is becouse:


    - not all smart tvs output 5.1 compressed audio via optical. many just send stereo signal.

    - meanly becouse if you hook up your nvidia card to your tv, the EDID code from the tv will tell the card to send only R L sound signal (stereo). EDID codes act like an id between devices over hdmi and stablishe how the sound is delivered, 2.0 2.1 5.1 or wathever. Your tv has an EDID code that differs from the receivers code. NVIDIA use to had 5.1 capabilities over hdmi. Some people have reported succesfully using Custom Resolution Utility to patch the driver, making up a EDID code and fooling the card to identify the tv as a receiver, but this was crippled in the lastest 6 months driver iteration


    EDID codes are a requirement of hdcp protocol, long time ago cracked, and were thinked as a form of fighting piracy.


    Instead you can:

    Using optical - Use prologic mode (virtual surround or fake 5.1. The name can change from brand to brand) on your receiver.

    Using HDMI   - Buying a EDID box to clone the signal from your card. One cable to tv, the other one to the receiver. This is a hit or miss and there is no warranty that the box will output 5.1 audio, This will work only if your receiver has hdm in.


    I have an almost equal setup as yours and ended up using prologic decode (fake 5.1) mode of my receiver, It is not perfect, but works



  2. You don't need a bt sounbar. Just buy a bt adapter to hook up your 3.5 mm output from your tv ro the RCA input ports to a bt transmiter like this one 


    Aditionally you Will need a 3.5 mm to RCA cable to make it works

  3. It's possible and I did it. I have the same setup that you describe, except for the LG tv (I own a Samsung tv).


    I run windows 7 Ultimate. So bear in mind when you follow this steps.


    - Setup your tv to playback sound over external speakers (Check the user manual)

    - Connect one extreme of your optical cable to the optical output from your tv

    - Connect the other extreme to the S/pdif optical in of the sound card

    - Connect the green, orange and black 3.5 mm cables to the front panel of the sound card

    - To make windows playback from the optical cable over your logitech x -540, setup the recording devices to listen from that port, (the menues are in spanish, but the tab location are the same in every windows 7). The default playback device must be the usb multi channel device.


    Ask if you have any doubt.


    Note. The usb version is better, and works. No need for a power cord.


    My card is not manufacture anymore, but these are its equivalent on Amazon, same chip, another brands.









  4. The optical port on your tv it is in fact an out put.

    In your DAC   =>  Inputs:  Modi 2 Uber: USB, Toslink SPDIF, Coaxial SPDIF
    if you connect your optical output (toslink cable) from your Tv to the optical input into your DAC, it will work. In this case you will be using your tv as the receiver for the ps4 or any other hdmi device.

    I assume you have hooked up your speakers to your pc using the usb port in your DAC.as the source.

    In this case, only one aditional cable is require to acomplish your wish.

    To change between sources, toslink (optical) and usb, go to properties on sound devices on windows.

    You must set up your preferences in your audio tv options to external speakers.



    ARC stands for Audio Return Channel. ARC enables the TV to output digital sound via the HDMI (ARC) port. However, ARC is only available when the TV is connected to an audio receiver that supports ARC.



  5. Youtube will playback stereo by deffault.

    I assume you have Logitech speakers. Those have a button (dot matrix I think..) that let you activate something similar to dolby prologic, wich let you run an emulated 5.1 signal from a stereo one. It is not real 5.1, but it will fill the space of your sepakers if that is you want to do.

    USB and Optical (preferred method)

    If the computer has optical out and supports Dolby Live, the ideal setup will involve routing the game audio via Dolby Digital to the optical output on the computer.  Then, route the chat application audio to the USB audio on the LS40.  This setup will allow the left volume wheel to control game volume and mic monitor level while the right volume wheel will control the chat volume level, just as it does on a console.  It is also the only way to experience full Surround Sound on the PC.  Since Macs do not support Dolby Live, only pre-recorded content such a movies will be able to use surround sound.  Games will be limited to stereo.


    USB Only

    Connect the wireless dongle to a USB port on a PC or Mac.  This allows routing of both stereo audio and the microphone via USB.  You'll need to refer to the User Guide for your computer's OS as the setup for this varies depending on the version of Windows or Mac OS in use.  Set "LucidSound PC Gaming Audio" speaker as the default audio output and set "LucidSound PC Chat audio" as the default communication device.  The left side volume wheel will adjust game volume and the mic monitor level. The right side volume wheel will control chat volume level.  The EQ button will be able to switch through the 3 stereo modes.


    3.5mm Cable

    While the headset is powered OFF, simply connect one end of the 3.5mm chat cable to the headset and the other end to the computer's 3.5mm jack.  If the computer has separate pink/green 3.5mm jacks for audio, a splitter is required.  

  7. With your actual headphones, You won't notice any significant improvement, even with a dedicated DAC/ headphone amp.

    Your on board sound is just right.

    To use the Supreme fx hi-fi in with your setup, you will need a jumped pc power supply and an extended usb header (most not came longer than a few inches), with all the cables hanging around. It is, in my opinion a hassle.
