Steel111 :
I am thinking of getting Asus Xonar D2X Sound Card for razer tiamat 7.1 headphones. But I also have LG bh9530 home theatre, and I am not sure how to connect the analog outputs of the sound card into the home theatre. Do such home theatres require sound cards at all? Right now I am using a 3.5mm to 2x 2.5mm converter and feeding sound from my motherboard's sound card into the home theatre.
Please advice
The BH would take 5 stereo 3.5mm 1 for L/R main, 1 for Centre and Sub(LF), 1 for Left Front/Right Front, 1 for Left Mid/RightMid and 1 for LeftRear/RightRear.
However, the only thing I know that can put out 10 channels of audio is a pro audio interface and I certainly don't know any movies out there delivering 9.1 audio.
Yours however claims to come with a USB connector as well as ethernet and Wi-Fi so you should be good to go without audio cables. Personally I would recommend them however. The convertors are bound to be substandard in a 9.1 home audio system as they expect you to have your own DAC at that price point.
