I have a samsung plasma 3DTV 47". The only audio options available for this are its speakers and digital audio. I can't find any speakers that accept digital audio IN so what I did was connect my laptop and tv via hdmi and 2.1 speakers through the 3.5mm of the laptop. (I'm not using speaker systems such as 5.1 coz my room is too small. 2.1 is already too loud)
I found an audio optical converter which converts optical to RCA (red and white) so I bought it + the cable. Now i don't have to use the laptop anymore. I plugged in a hard drive to the tv and started a movie but to my dismay the sounds coming from the speakers connected via RCA to the optical converter which is connected to the optical audio out of the tv is soooooo soft even at max volume. But when i change the source to TV, or ps3, the volume is normal. Any help, tips, explanation? Thank you.
