With the new TV, there was one more addition - movies on weekend! Many came with multichannel audio like Dolby and I always wondered how it sounds. Just recently I had an idea and today its implemented.
The PC supported 4CH output using built in Realtek HD audio chipset. With this I was good to go.
I connected the TV speakers as front L+R channels using straight stereo cable. Then I got an male-female stereo extension cable and connected 2.1 set as Rear L+R.The Realtek driver needed to explicitely put the output into 4CH mode and voilla! A simple 4 channel home theatre setup is available!!
Tested the playback using VLC and it sounds better than before!!!
